-Preferably send an email to kovid at kovidgoyal.net or open a private security
-advisory using the GitHub security advisory facility.
-
-Note that I will generally respond to security communication within 72 hours. Once
-the bug is confirmed, it will be fixed or at least mitigated within another 72
-hours, at which time the fix will typically be committed to master and hence be

 Recent major new features
 ---------------------------
 
-Sessions [0.43]
-~~~~~~~~~~~~~~~~
-
-kitty has long had support for :doc:`sessions`, aka simple text files where you
-can define what tabs, windows and programs you wish to run in kitty. Now in
-addition to that kitty has the ability to :ref:`create and switch between
-sessions <goto_session>` with a single keypress and also to manually setup some
-tabs/windows in kitty and :ref:`save it as a session file <complex_sessions>`,
-for seamless and intuitive session file creation.
-
-A scrollbar for the kitty scrollback [0.43]
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-A long requested feature, kitty has finally :pull:`gotten a scrollbar <8945>`
-that can be used with the mouse for browsing its scrollback. The bar appear
-automatically when you start scrolling backwards and is :opt:`extensively
-configurable <scrollbar>` in kitty.conf. Note that the old ``scrollback_indicator_opacity``
-option is deprecated.
-
-Multiple cursors [0.43]
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-kitty has pioneered a new :doc:`escape code protocol
-<multiple-cursors-protocol>` that allows terminal applications to use multiple
-cursors, rendered natively. These are typically used in editors to make the
-same edit at multiple locations. Now terminal based editors can use properly
-rendered native cursors, just like their GUI cousins, at last.
-
-Access kitty with a single keypress [0.42]
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-.. include:: quake-screenshots.rst
-
-kitty now has a Quake like floating, translucent terminal window, so you can access
-all that kitty goodness instantly with a single keypress.
-
-See the screenshots on the side and head over to the :doc:`kitten page for details
-on how to set it up </kittens/quick-access-terminal>`.
-
-
-Multiple sized text [0.40]
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-kitty is the first major terminal to introduce the concept of multiple sized
-text. Terminal programs running in kitty can now opt-in to use and display text
-in multiple font sizes both larger and smaller than the base font size. This is
-done in a backwards compatible, opt-in way that does not affect how traditional
-terminal programs work at all. For details on the new feature and how to use
-it, see :doc:`text-sizing-protocol`.
-
-Cursor trails [0.37]
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Show an animated trail when the text cursor makes large jumps making it easy
-to follow cursor movements. Inspired by the similar feature in neovide, but
-works with terminal multiplexers and kitty windows as well. See :pull:`the pull
-request <7970>` for a demonstration video. This feature is optional and must be
-turned on by the :opt:`cursor_trail` option in :file:`kitty.conf`.
-
-
-Variable font support [0.36]
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Terminal aficionados spend all day staring at text, so getting text
-rendering just right is very important. In that spirit, kitty now supports
-`OpenType Variable fonts <https://en.wikipedia.org/wiki/Variable_font>`__.
-These allow precise customisation of font characteristics, such as weight and
-spacing. Not only that, kitty now has a new :doc:`choose-fonts
-<kittens/choose-fonts>` kitten that provides a UI for choosing fonts with
-support for font features, variable fonts and previews of how the font will
-look. This is in addition to its existing best-in-class font customization
-abilities, such as: :opt:`symbol_map`, :opt:`text_composition_strategy`,
-:opt:`font_features` and :opt:`modify_font`. kitty knows text rendering is
-important, and goes the extra mile for it.
-
-Desktop notifications [0.36]
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-|kitty| now has a :doc:`notify </kittens/notify>` kitten that can be used to
-display desktop notifications from the command line, even over SSH. It has
-support for icons, buttons, updating notifications, waiting till
-the notification is closed, etc. The underlying :doc:`desktop-notifications`
-protocol has been expanded to support all these features.
-
-Wayland goodies [0.34]
-~~~~~~~~~~~~~~~~~~~~~~~
-
-Wayland users should rejoice as kitty now comes with major Wayland
-quality-of-life improvements:
-
-* Draw GPU accelerated :doc:`desktop panels and background </kittens/panel>`
-  running arbitrary terminal programs. For example, run `btop
-  <https://github.com/aristocratos/btop/>`__ as your desktop background
-
-* Background blur for transparent windows is now supported under KDE
-  using a custom KDE specific protocol
-
-* The kitty window decorations in GNOME are now fully functional with buttons
-  and they follow system dark/light mode automatically
-
-* kitty now supports fractional scaling in Wayland which means pixel perfect
-  rendering when you use a fractional scale with no wasted performance on
-  resizing an overdrawn pixmap in the compositor
-
-With this release kitty's Wayland support is now on par with X11, provided
-you use a decent Wayland compositor.

@@ -129,782 +22,47 @@ kitty was already so fast that its performance was never a bottleneck, this

+
+File transfer over the tty device
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Transfer files to and from remote computers over the ``TTY`` device itself.
+This means that file transfer works over nested SSH sessions, serial links,
+etc. Anywhere you have a terminal device, you can transfer files.
+
+Simply ssh into a remote computer using the :doc:`ssh kitten </kittens/ssh>`
+and run the :doc:`transfer kitten </kittens/transfer>` (which the ssh kitten
+makes available for you on the remote computer automatically). For example, to
+copy a file from a remote computer::
+
+    <local computer>  $ kitten ssh my-remote-computer
+    <remote computer> $ kitten transfer some-file /path/on/local/computer
+
+The kitten can transfer files to and from the remote computer. It supports
+recursive transfer of directories, symlinks and hardlinks. It can even use the
+rsync algorithm to speed up repeated transfers of large files.

-     using a password to avoid repeated confirmations
-
-If a program like an editor wants to make use of the system clipboard, by
-default, the user is prompted on every read request. This can become quite
-fatiguing. To avoid this situation, this protocol allows sending a password
-and human friendly name with ``type=write`` and ``type=read`` requests. The
-terminal can then ask the user to allow all future requests using that
-password. If the user agrees, future requests on the same tty will be
-automatically allowed by the terminal. The editor or other program using
-this facility should ideally use a password randomnly generated at startup,
-such as a UUID4. However, terminals may implement permanent/stored passwords.
-Users can then configure terminal programs they trust to use these password.
-
-The password and the human name are encoded using the ``pw`` and ``name`` keys
-in the metadata. The values are UTF-8 strings that are base64 encoded.
-Specifying a password without a human friendly name is equivalent to not
-specifying a password and the terminal must treat the request as though

-Setting and querying colors
--------------------------------
-
-While there exists a legacy protocol developed by XTerm for querying and
-setting colors, as with most XTerm protocols it suffers from the usual design
-limitations of being under specified and in-sufficient. XTerm implements
-querying of colors using OSC 4,5,6,10-19,104,105,106,110-119. This absurd
-profusion of numbers is completely unnecessary, redundant and requires adding
-two new numbers for every new color. Also XTerm's protocol doesn't handle the
-case of colors that are unknown to the terminal or that are not a set value,
-for example, many terminals implement selection as a reverse video effect not a
-fixed color. The XTerm protocol has no way to query for this condition. The
-protocol also doesn't actually specify the format in which colors are reported,
-deferring to a man page for X11!
-
-Instead kitty has developed a single number based protocol that addresses all
-these shortcomings and is future proof by virtue of using string keys rather
-than numbers. The syntax of the escape code is::
-
-    <OSC> 21 ; key=value ; key=value ; ... <ST>
-
-The spaces in the above definition are for reading clarity and should be ignored.
-Here, ``<OSC>`` is the two bytes ``0x1b (ESC)`` and ``0x5d (])``. ``ST`` is
-either ``0x7 (BEL)`` or the two bytes ``0x1b (ESC)`` and ``0x5c (\\)``.
-
-``key`` is a number from 0-255 to query or set the color values from the
-terminals ANSI color table, or one of the strings in the table below for
-special colors:

-
-Querying current color values
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-To query colors values, the client program sends this escape code with the
-``value`` field set to ``?`` (the byte ``0x3f``). The terminal then responds
-with the same escape code, but with the ``?`` replaced by the :ref:`encoded
-color value <color_control_color_encoding>`. If the queried color is one that
-does not have a defined value, for example, if the terminal is using a reverse
-video effect or a gradient or similar, then the value must be empty, that is
-the response contains only the key and ``=``, no value. For example, if the
-client sends::
-
-    <OSC> 21 ; foreground=? ; cursor=? <ST>
-
-The terminal responds::
-
-    <OSC> 21 ; foreground=rgb:ff/00/00 ; cursor= <ST>
-
-This indicates that the foreground color is red and the cursor color is
-undefined (typically the cursor takes the color of the text under it and the
-text takes the color of the background).
-
-If the terminal does not know a field that a client send to it for a query it
-must respond back with the ``field=?``, that is, it must send back a question
-mark as the value.
-
-
-Setting color values
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-To set a color value, the client program sends this escape code with the
-``value`` field set to either an :ref:`encoded color value
-<color_control_color_encoding>` or the empty value. The empty value means
-the terminal should use a dynamic color for example reverse video for
-selections or similar. To reset a color to its default value (i.e. the value it
-would have if it was never set) the client program should send just the key
-name with no ``=`` and no value. For example::
-
-    <OSC> 21 ; foreground=green ; cursor= ; background <ST>
-
-This sets the foreground to the color green, sets the cursor color to dynamic
-(usually meaning the cursor takes the color of the text under it) and resets
-the background color to its default value.
-
-To check if setting succeeded, the client can simply query the color, in fact
-the two can be combined into a single escape code, for example::
-
-    <OSC> 21 ; foreground=white ; foreground=? <ST>
-
-The terminal will change the foreground color and reply with the new foreground
-color.
-
-
-.. _color_control_color_encoding:
-
-Color value encoding
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The color encoding is inherited from the scheme used by XTerm, for
-compatibility, but a sane, rigorously specified subset is chosen.
-
-RGB colors are encoded in one of three forms:
-
-``rgb:<red>/<green>/<blue>``
-    | <red>, <green>, <blue> := h | hh | hhh | hhhh
-    | h := single hexadecimal digits (case insignificant)
-    | Note that h indicates the value scaled in 4 bits, hh the value scaled in 8 bits,
-      hhh the value scaled in 12 bits, and hhhh the value scaled in 16 bits, respectively.
-
-``#<h...>``
-    | h := single hexadecimal digits (case insignificant)

-    | #RRRGGGBBB      (12 bits each)
-    | #RRRRGGGGBBBB   (16 bits each)
-    | The R, G, and B represent single hexadecimal digits.  When fewer than 16 bits
-      each are specified, they represent the most significant bits of the value

-``rgbi:<red>/<green>/<blue>``
-    red, green, and blue are floating-point values between 0.0 and 1.0, inclusive. The input format for these values is an optional
-    sign, a string of numbers possibly containing a decimal point, and an optional exponent field containing an E or e followed by a possibly
-    signed integer string. Values outside the ``0 - 1`` range must be clipped to be within the range.
-
-If a color should have an alpha component, it must be suffixed to the color
-specification in the form :code:`@number between zero and one`. For example::
-
-    red@0.5 rgb:ff0000@0.1 #ff0000@0.3
-
-The syntax for the floating point alpha component is the same as used for the
-components of ``rgbi`` defined above. When not specified, the default alpha
-value is ``1.0``. Values outside the range ``0 - 1`` must be clipped
-to be within the range, negative values may have special context dependent
-meaning.
-
-In addition, the following color names are accepted (case-insensitively) corresponding to the
-specified RGB values.

-
-
-Being informed when a notification is closed
-------------------------------------------------
-
-.. versionadded:: 0.36.0
-   Notifications of close events
-
-If you wish to be informed when a notification is closed, you can specify
-``c=1`` when sending the notification. For example::
-
-    <OSC> 99 ; i=mynotification : c=1 ; hello world <terminator>
-
-Then, the terminal will send the following
-escape code to inform when the notification is closed::
-
-    <OSC> 99 ; i=mynotification : p=close ; <terminator>
-
-If no notification id was specified ``i=0`` will be used in the response
-
-If ``a=report`` is specified and the notification is activated/clicked on
-then both the activation report and close notification are sent. If the notification
-is updated then the close event is not sent unless the updated notification
-also requests a close notification.
-
-Note that on some platforms, such as macOS, the OS does not inform applications
-when notifications are closed, on such platforms, terminals reply with::
-
-    <OSC> 99 ; i=mynotification : p=close ; untracked <terminator>
-
-This means that the terminal has no way of knowing when the notification is
-closed. Instead, applications can poll the terminal to determine which
-notifications are still alive (not closed), with::
-
-    <OSC> 99 ; i=myid : p=alive ; <terminator>
-
-The terminal will reply with::
-
-    <OSC> 99 ; i=myid : p=alive ; id1,id2,id3 <terminator>
-
-Here, ``myid`` is present for multiplexer support. The response from the terminal
-contains a comma separated list of ids that are still alive.
-
-
-Updating or closing an existing notification
-----------------------------------------------
-
-.. versionadded:: 0.36.0
-   The ability to update and close a previous notification
-
-To update a previous notification simply send a new notification with the same
-*notification id* (``i`` key) as the one you want to update. If the original
-notification is still displayed it will be replaced, otherwise a new
-notification is displayed. This can be used, for example, to show progress of
-an operation. How smoothly the existing notification is replaced
-depends on the underlying OS, for example, on Linux the replacement is usually flicker
-free, on macOS it isn't, because of Apple's design choices.
-Note that if no ``i`` key is specified, no updating must take place, even if
-there is a previous notification without an identifier. The terminal must
-treat these as being two unique *unidentified* notifications.
-
-To close a previous notification, send::
-
-    <OSC> i=<notification id> : p=close ; <terminator>
-
-This will close a previous notification with the specified id. If no such
-notification exists (perhaps because it was already closed or it was activated)
-then the request is ignored. If no ``i`` key is specified, this must be a no-op.
-
-
-Automatically expiring notifications
--------------------------------------
-
-A notification can be marked as expiring (being closed) automatically after
-a specified number of milliseconds using the ``w`` key. The default if
-unspecified is ``-1`` which means to use whatever expiry policy the OS has for
-notifications. A value of ``0`` means the notification should never expire.
-Values greater than zero specify the number of milliseconds after which the
-notification should be auto-closed. Note that the value of ``0``
-is best effort, some platforms honor it and some do not. Positive values
-are robust, since they can be implemented by the terminal emulator itself,
-by manually closing the notification after the expiry time. The notification
-could still be closed before the expiry time by user interaction or OS policy,
-but it is guaranteed to be closed once the expiry time has passed.
-
-
-Adding icons to notifications
---------------------------------
-
-.. versionadded:: 0.36.0
-   Custom icons in notifications
-
-Applications can specify a custom icon to be displayed with a notification.
-This can be the application's logo or a symbol such as error or warning
-symbols. The simplest way to specify an icon is by *name*, using the ``n``
-key. The value of this key is :ref:`base64` encoded UTF-8 text. Names
-can be either application names, or symbol names. The terminal emulator
-will try to resolve the name based on icons and applications available
-on the computer it is running on. The following list of well defined names
-must be supported by any terminal emulator implementing this spec.
-The ``n`` key can be specified multiple times, the terminal will go through
-the list in order and use the first icon that it finds available on the
-system.

-If an icon name is an application name it should be an application identifier,
-such as the filename of the application's :file:`.desktop` file on Linux or its
-bundle identifier on macOS. For example if the cross-platform application
-FooBar has a desktop file named: :file:`foo-bar.desktop` and a bundle
-identifier of ``net.foo-bar-website.foobar`` then it should use the icon names
-``net.foo-bar-website.foobar`` *and* ``foo-bar`` so that terminals running on
-both platforms can find the application icon.
-
-If no icon is specified, but the ``f`` key (application name) is specified, the
-terminal emulator should use the value of the ``f`` key to try to find a
-suitable icon.
-
-Adding icons by transmitting icon data
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This can be done by using the ``p=icon`` key. Then, the payload is the icon
-image in any of the ``PNG``, ``JPEG`` or ``GIF`` image formats. It is recommended
-to use an image size of ``256x256`` for icons. Since icons are binary data,
-they must be transmitted encoded, with ``e=1``.
-
-When both an icon name and an image are specified, the terminal emulator must
-first try to find a locally available icon matching the name and only if one
-is not found, fallback to the provided image. This is so that users are
-presented with icons from their current icon theme, where possible.
-
-Transmitted icon data can be cached using the ``g`` key. The value of the ``g``
-key must be a random globally unique UUID like :ref:`identifier`. Then, the
-terminal emulator will cache the transmitted data using that key. The cache
-should exist for as long as the terminal emulator remains running. Thus, in
-future notifications, the application can simply send the ``g`` key to display
-a previously cached icon image with needing to re-transmit the actual data with
-``p=icon``. The ``g`` key refers only to the icon data, multiple different
-notifications with different icon or application names can use the same ``g``
-key to refer to the same icon. Terminal multiplexers must cache icon data
-themselves and refresh it in the underlying terminal implementation when
-detaching and then re-attaching. This means that applications once started
-need to transmit icon data only once until they are quit.
+*should* either ignore the entire escape code or perform a best guess effort
+to display it based on what it does understand.
 
 .. note::
-   To avoid DoS attacks terminal implementations can impose a reasonable max size
-   on the icon cache and evict icons in order of last used. Thus theoretically,
-   a previously cached icon may become unavailable, but given that icons are
-   small images, practically this is not an issue in all but the most resource
-   constrained environments, and the failure mode is simply that the icon is not
-   displayed.
+   It is possible to extend this escape code to allow specifying an icon for
+   the notification, however, given that some platforms, such as legacy versions
+   of macOS, don't allow displaying custom images on a notification, it was
+   decided to leave it out of the spec for the time being.
 
-.. note::
-   How the icon is displayed depends on the underlying OS notifications
-   implementation. For example, on Linux, typically a single icon is displayed.
-   On macOS, both the terminal emulator's icon and the specified custom icon
-   are displayed.
+   Similarly, features such as scheduled notifications could be added in future
+   revisions.
 
 
-Adding buttons to the notification
----------------------------------------
-
-Buttons can be added to the notification using the *buttons* payload, with ``p=buttons``.
-Buttons are a list of UTF-8 text separated by the Unicode Line Separator
-character (U+2028) which is the UTF-8 bytes ``0xe2 0x80 0xa8``. They can be
-sent either as :ref:`safe_utf8` or :ref:`base64`. When the user clicks on one
-of the buttons, and reporting is enabled with ``a=report``, the terminal will
-send an escape code of the form::
-
-    <OSC> 99 ; i=identifier ; button_number <terminator>
-
-Here, `button_number` is a number from 1 onwards, where 1 corresponds
-to the first button, two to the second and so on. If the user activates the
-notification as a whole, and not a specific button, the response, as described
-above is::
-
-    <OSC> 99 ; i=identifier ; <terminator>
-
-If no identifier was specified when creating the notification, ``i=0`` is used.
-The terminal *must not* send a response unless report is requested with
-``a=report``.
-
-.. note::
-
-   The appearance of the buttons depends on the underlying OS implementation.
-   On most Linux systems, the buttons appear as individual buttons on the
-   notification. On macOS they appear as a drop down menu that is accessible
-   when hovering the notification. Generally, using more than two or three
-   buttons is not a good idea.

-Playing a sound with notifications
------------------------------------------
-
-.. versionadded:: 0.36.0
-   The ability to control the sound played with notifications
-
-By default, notifications may or may not have a sound associated with them
-depending on the policies of the OS notifications service. Sometimes it
-might be useful to ensure a notification is not accompanied by a sound.
-This can be done by using the ``s`` key which accepts :ref:`base64` encoded
-UTF-8 text as its value. The set of known sounds names is in the table below,
-any other names are implementation dependent, for instance, on Linux, terminal emulators will
-probably support the `standard sound names
-<https://specifications.freedesktop.org/sound-naming-spec/latest/#names>`__

-   ``error``                A sound associated with error messages

-Support for sound names can be queried as described below.
-
-
-Querying for support
--------------------------
-
-.. versionadded:: 0.36.0
-   The ability to query for support
-
-An application can query the terminal emulator for support of this protocol, by
-sending the following escape code::
-
-    <OSC> 99 ; i=<some identifier> : p=? ; <terminator>
-
-A conforming terminal must respond with an escape code of the form::
-
-    <OSC> 99 ; i=<some identifier> : p=? ; key=value : key=value <terminator>
-
-The identifier is present to support terminal multiplexers, so that they know
-which window to redirect the query response too.
-
-Here, the ``key=value`` parts specify details about what the terminal
-implementation supports. Currently, the following keys are defined:
-
-=======  ================================================================================
-Key      Value
-=======  ================================================================================
-``a``    Comma separated list of actions from the ``a`` key that the terminal
-         implements. If no actions are supported, the ``a`` key must be absent from the
-         query response.
-
-``c``    ``c=1`` if the terminal supports close events, otherwise the ``c``
-         must be omitted.
-
-``o``    Comma separated list of occasions from the ``o`` key that the
-         terminal implements. If no occasions are supported, the value
-         ``o=always`` must be sent in the query response.
-
-``p``    Comma separated list of supported payload types (i.e. values of the
-         ``p`` key that the terminal implements). These must contain at least
-         ``title``.
-
-``s``    Comma separated list of sound names from the table of standard sound names above.
-         Terminals will report the list of standard sound names they support.
-         Terminals *should* support at least ``system`` and ``silent``.
-
-``u``    Comma separated list of urgency values that the terminal implements.
-         If urgency is not supported, the ``u`` key must be absent from the
-         query response.
-
-``w``    ``w=1`` if the terminal supports auto expiring of notifications.
-=======  ================================================================================
-
-In the future, if this protocol expands, more keys might be added. Clients must
-ignore keys they do not understand in the query response.
-
-To check if a terminal emulator supports this notifications protocol the best way is to
-send the above *query action* followed by a request for the `primary device
-attributes <https://vt100.net/docs/vt510-rm/DA1.html>`_. If you get back an
-answer for the device attributes without getting back an answer for the *query
-action* the terminal emulator does not support this notifications protocol.

-Selecting files, fast
-========================
-
-.. only:: man
-
-    Overview
-    --------------
-
-.. versionadded:: 0.43.0
-
-The choose-files kitten is designed to allow you to select files, very fast,
-with just a few key strokes. It operates like `fzf
-<https://github.com/junegunn/fzf/>`__ and similar fuzzy finders, except that
-it is specialised for finding files. As such it supports features such as
-filtering by file type, file type icons, content previews and
-so on, out of the box. It can be used as a drop in (but much more efficient and
-keyboard friendly) replacement for the :guilabel:`File open and save`
-dialog boxes common to GUI programs. On Linux, with the help of the
-:doc:`desktop-ui </kittens/desktop-ui>` kitten, you can even convince
-most GUI programs on your computer to use this kitten instead of regular file
-dialogs.
-
-Simply run it as::
-
-    kitten choose-files
-
-to select a single file from the tree rooted at the current working directory.
-Type a few letters from the filename and once it becomes the top selection,
-press :kbd:`Enter`. You can change the current directory by instead selecting a
-directory and pressing the :kbd:`Tab` key. :kbd:`Shift+Tab` goes up one
-directory level.
-
-Creating shortcuts to favorite/frequently used directories
-------------------------------------------------------------
-
-You can create keyboard shortcuts to quickly switch to any directory in
-:file:`choose-files.conf`. For example:
-
-.. code-block:: conf
-
-   map ctrl+t cd /tmp
-   map alt+p  cd ~/my/project
-
-Selecting multiple files
------------------------------
-
-When you wish to select multiple files, start the kitten with :option:`--mode
-<kitty +kitten choose_files --mode>`:code:`=files`. Then instead of pressing
-:kbd:`Enter`, press :kbd:`Shift+Enter` instead and the file will be added to the list
-of selections. You can also hold the :kbd:`Ctrl` key and click on files to add
-them to the selections. Similarly, you can hold the :kbd:`Alt` key and click to
-select ranges of files (similar to using :kbd:`Shift+click` in a GUI app).
-Press :kbd:`Enter` on the last selected file to finish. The list of selected
-files is displayed at the bottom of the kitten and you can click on them
-to deselect a file. Similarly, pressing :kbd:`Shift+Enter` will un-select a
-previously selected file.
-
-
-Hidden and ignored files
---------------------------
-
-By default, the kitten does not process hidden files and directories (whose
-names start with a period). This can be :opt:`changed in the configuration <kitten-choose_files.show_hidden>`
-and also at runtime via the clickable link to the right of the search input.
-
-Similarly, the kitten respects both :file:`.gitignore` and :file:`.ignore`
-files, by default. This can also be changed both :opt:`in configuration
-<kitten-choose_files.respect_ignores>` or at runtime. Note that
-:file:`.gitignore` files are only respected if there is also a :file:`.git`
-directory present. The kitten also supports the global :file:`.gitignore` file,
-though it applies only inside git working trees. You can specify :opt:`global ignore
-patterns <kitten-choose_files.ignore>`, that apply everywhere in :file:`choose-files.conf`.
-
-
-Selecting non-existent files (save file names)
--------------------------------------------------
-
-This kitten can also be used to select non-existent files, that is a new file
-for a :guilabel:`Save file` type of dialog using :option:`--mode <kitty +kitten
-choose_files --mode>`:code:`=save-file`. Once you have changed to the directory
-you want the file to be in (using the :kbd:`Tab` key),
-press :kbd:`Ctrl+Enter` and you will be able to type in the file name.
-
-
-Selecting directories
----------------------------
-
-This kitten can also be used to select directories,
-for an :guilabel:`Open directory` type of dialog using :option:`--mode <kitty +kitten

-Changing kitty fonts
-========================
-
-.. only:: man
-
-    Overview
-    --------------
-
-Terminal aficionados spend all day staring at text, as such, getting text
-rendering just right is very important. kitty has extremely powerful facilities
-for fine-tuning text rendering. It supports `OpenType features
-<https://en.wikipedia.org/wiki/List_of_typographic_features>`__ to select
-alternate glyph shapes, and `Variable fonts
-<https://en.wikipedia.org/wiki/Variable_font>`__ to control the weight or
-spacing of a font precisely. You can also :opt:`select which font is used to
-render particular unicode codepoints <symbol_map>` and you can :opt:`modify
-font metrics <modify_font>` and even :opt:`adjust the gamma curves
-<text_composition_strategy>` used for rendering text onto the background color.
-
-The first step is to select the font faces kitty will use for rendering
-regular, bold and italic text. kitty comes with a convenient UI for choosing fonts,
-in the form of the *choose-fonts* kitten. Simply run::
-
-    kitten choose-fonts
-
-and follow the on screen prompts.
-
-First, choose the family you want, the list of families can be easily filtered by
-typing a few letters from the family name you are looking for. The family
-selection screen shows you a preview of how the family looks.
-
-.. image:: ../screenshots/family-selection.png
-   :alt: Choosing a family with the choose fonts kitten
-   :width: 600
-
-Once you select a family by pressing the :kbd:`Enter` key, you
-are shown previews of what the regular, bold and italic faces look like
-for that family. You can choose to fine tune any of the faces. Start with
-fine-tuning the regular face by pressing the :kbd:`R` key. The other styles
-will be automatically adjusted based on what you select for the regular face.
-
-.. image:: ../screenshots/font-fine-tune.png
-   :alt: Fine tune a font by choosing a precise weight and features
-   :width: 600
-
-You can choose a specific style or font feature by clicking on it. A precise
-value for any variable axes can be selected using the slider, in the screenshot
-above, the font supports precise weight adjustment. If you are lucky the font
-designer has included descriptive names for font features, which will be
-displayed, if not, consult the documentation of the font to see what each feature does.
-
-.. _font_spec_syntax:
-
-The font specification syntax
---------------------------------
-
-If you don't like the choose fonts kitten or simply want to understand and
-write font selection options into :file:`kitty.conf` yourself, read on.
-
-There are four font face selection keys: `font_family`, `bold_font`,
-`italic_font` and `bold_italic_font`. Each of these supports the syntax
-described below. Their values can be of three types, either a
-font family name, the keyword ``auto`` or an extended ``key=value`` syntax
-for specifying font selection precisely.
-
-If a font family name is specified kitty will use Operating System APIs to
-search for a matching font. The keyword ``auto`` means kitty will choose a font
-completely automatically, typically this is used for automatically selecting
-bold/italic variants once the :opt:`font_family` is set. The bold and italic
-variants will then automatically use the same set of features as the main face.
-
-To specify font face selection more precisely, a ``key=value`` syntax is used.
-First, let's look at a few examples::
-
-    # Select by family only, actual face selection is automatic
-    font_family family="Fira Code"
-    # Select an exact face by Postscript name
-    font_family postscript_name=FiraCode
-    # Select an exact face by family with features and variable weight
-    font_family family=SourceCodeVF variable_name=SourceCodeUpright features="+zero cv01=2" wght=380
-
-The following are the known keys, any other keys are names of *variable axes*,
-that is, they are used to set the variable value for some font characteristic.
-
-``family``
-    A font family name. A family typically has multiple actual font faces, such
-    as bold and italic variants. One or more of the faces can even be variable,
-    allowing fine tuning of font characteristics.
-
-``style``
-    A style name to choose a particular font from a given family. Useful only
-    with the ``family`` key, when no more precise methods for face selection
-    are specified. Can also be used to specify a named variable style for
-    variable fonts.
-
-``postscript_name``
-    The actual postscript name for a font face. This allows selecting a
-    particular variant within a font family. But note that postscript names
-    are usually insufficient for selecting variable fonts.
-
-``full_name``
-    This can be used to select a particular font face in a family. However, it
-    is less precise than ``postscript_name`` and should not generally be used.
-
-``variable_name``
-    Some families with variable fonts actually contain multiple font files. For
-    example, a family could have variable weights with one font file containing
-    upright variable weight faces and another containing italic variable weight
-    faces. Well designed fonts use a *variable name* to distinguish between
-    such files. Should be used in conjunction with ``family`` to select a
-    particular variable font file.
-
-``features``
-    A space separated list of OpenType font features to enable/disable or
-    select a value of, for this font. Consult the documentation for the font
-    family to see what features it supports and their effects. The exact syntax
-    for specifying features is `documented by HarfBuzz
-    <https://harfbuzz.github.io/harfbuzz-hb-common.html#hb-feature-from-string>`__
-
-``system``
-    This can be used to pass an arbitrary string, usually a family or full name
-    to the OS font selection APIs. Should not be used in conjunction with any
-    other keys. Is the same as specifying just the font name without any keys.
-
-
-In addition to these keys, any four letter key is treated as the name of a
-variable characteristic of the font. Its value is used to set the value for
-the name.

-Using terminal programs to provide Linux desktop components
-===============================================================
-
-.. only:: man
-
-    Overview
-    --------------
-
-.. versionadded:: 0.43.0
-
-Power users of terminals on Linux also often like to use bare bones window
-managers instead of full fledged desktop environments. This kitten helps
-provide parts of the desktop environment that are missing from such setups,
-and does so using keyboard friendly, terminal first UI components. Some of its
-features are:
-
-* Replace the typical File Open/Save dialogs used in GUI programs with the
-  fast and keyboard centric :doc:`choose-files </kittens/choose-files>` kitten
-  running in a semi-transparent kitty overlay.
-
-* Allow simple command line based management of the desktop light/dark modes.
-
-
-How to install
--------------------
-
-.. note::
-
-   This kitten relies on the :doc:`panel kitten </kittens/panel>`
-   under the hood to supply UI components. Check :ref:`the documentation <panel_compat>`
-   of that kitten to see if your window manager works with it.
-
-First, run::
-
-    kitten desktop-ui enable-portal
-
-Then, set the following two environment variables, *system wide*, that means in
-:file:`/etc/environment` or the equivalent for your distribution::
-
-    QT_QPA_PLATFORMTHEME=xdgdesktopportal
-    GTK_USE_PORTAL=1
-
-
-Finally, reboot. Now, when you open a file dialog in most GUI applications, it
-should open the :doc:`choose-files kitten </kittens/choose-files>` instead
-of a normal file open dialog. You can change the current light/dark mode of
-your desktop by running::
-
-    kitten desktop-ui set-color-scheme dark
-    kitten desktop-ui set-color-scheme light
-
-Check the current value using::
-
-    dbus-send --session --print-reply --dest=org.freedesktop.portal.Desktop /org/freedesktop/portal/desktop org.freedesktop.portal.Settings.Read string:org.freedesktop.appearance string:color-scheme
-
-How it works
-----------------
-
-Modern Linux desktops have so called `portals
-<https://flatpak.github.io/xdg-desktop-portal/docs/index.html>`__ that were
-invented for sandboxed applications and provide various facilities to such
-applications over DBUS, including file open dialogs, common desktop settings,
-etc. This kitten works by implementing a backend for some of these services.
-
-Normal GUI applications can then be told to make use of these services, thereby
-allowing us to replace parts of the desktop experience as needed.
-
-There are multiple competing implementations of the backends. Each desktop
-environment like KDE or GNOME has it's own backend and many window managers
-provide implementations for some backends as well. Service discovery and
-configuring which backend to use happens via the :file:`xdg-desktop-portal`
-program, usually found at :file:`/usr/lib/xdg-desktop-portal`.
-
-It can be configured by files in :file:`~/.local/share/xdg-desktop-portal`. See
-`man portals.conf <https://man.archlinux.org/man/portals.conf.5>`__. The
-``kitten desktop-ui enable-portal`` command takes care of the setup for you
-automatically. If you want to customize exactly which services to use this
-kitten for, run the command and then edit the conf file that the command says
-it has patched.
-
-
-Troubleshooting
--------------------
-
-First, ensure that DBUS is able to auto-start the kitten when it is needed. If
-the kitten is not already running, try the following command::
-
-    dbus-send --session --print-reply --dest=org.freedesktop.impl.portal.desktop.kitty \
-        /net/kovidgoyal/kitty/portal org.freedesktop.DBus.Properties.GetAll \
-        string:net.kovidgoyal.kitty.settings
-
-If DBUS is able to start the kitten or if it is already running it will print
-out the version property, otherwise it will fail with an error. If it fails,
-check the file
-:file:`~/.local/share/dbus-1/services/org.freedesktop.impl.portal.desktop.kitty.service`
-that should have been created by the ``enable-portal`` command. It's ``Exec``
-key must point to the full path to the kitten executable.
-
-Next, check that the XDG portal system is actually using this kitten for its
-settings backend. Run::
-
-    dbus-send --session --print-reply --dest=org.freedesktop.portal.Desktop \
-        /org/freedesktop/portal/desktop org.freedesktop.portal.Settings.Read \
-        string:net.kovidgoyal.kitty string:status
-
-If this returns a reply then the kitten is being used, as expected. If it
-returns a not found error, then some other backend is being used for settings.
-
-Read the ``portals.conf`` man page and run::
-
-    /usr/lib/xdg-desktop-portal -r v
-
-this will output a lot of debug information, which should tell you which
-backend is chosen for which service. Read the debug output carefully to
-determine why the kitten is not being selected.
-
-If some GUI applications are not using the choose-files kitten for their file
-select dialogs, then make sure the environment variables mentioned above are
-set, you can also try running the the GUI application with them set explicitly,
-as::
-
-    QT_QPA_PLATFORMTHEME=xdgdesktopportal GTK_USE_PORTAL=1 my-gui-app
-
-Note that not all applications use portals, so if some particular application
-is failing to use the portal but others work, report the issue to that
-applications' developers.

-
-This creates a kitty background window and inside it runs the `btop
-<https://github.com/aristocratos/btop>`__ program to display the statistics.
-
-The floating quick access window was created by running::

-       zsh -c 'printf "\e]66;s=4;Quick access kitty in Hyprland\a\n\n\n\nAlso uses kitty to draw desktop background\n"'

-        which is technically supported by almost all Wayland compositors, but the
-        implementation in some of them is quite buggy.

-           Fully working, no known issues
-
-        🟠 **KDE** (kwin)
-           Mostly working, except that clicks outside background panels cause kwin to :iss:`erroneously hide the panel <8715>`. KDE uses an `undocumented mapping <https://invent.kde.org/plasma/kwin/-/blob/3dc5cee6b34792486b343098e55e7f2b90dfcd00/src/layershellv1window.cpp#L24>`__ under Wayland to set the window type from the :code:`kitten panel --app-id` flag. You might want to use :code:`--app-id=dock` so that KDE treats the window as a dock panel, and disables window appearing/disappearing animations for it.
-
-        🟠 **Sway**
-           Renders its configured background over the background window instead of
-           under it. This is because it uses the wlr protocol for backgrounds itself.
-
-        🟠 **river**
-           Breaks when hiding (unmapping) layer shell windows. This means the quick
-           access terminal is non-functional, but background and dock panels work.
-           More technically, when unmapping the surface (attaching a NULL buffer to
-           it) river continues to send configure events to the unmapped surface,
-           leading to Wayland protocol errors.
-
-        🔴 **GNOME** (mutter)
-           Does not implement the wlr protocol at all, nothing works.
-
-    .. tab:: macOS
-
-        Mostly everything works, with the notable exception that dock panels do not
-        prevent other windows from covering them. This is because Apple does not
-        provide and way to do this in their APIs.

-You can have kitty automatically change its color theme when the OS switches
-between dark, light and no-preference modes. In order to do this, run the theme
-kitten as normal and at the final screen select the option to save your chosen
-theme as either light, dark, or no-preference. Repeat until you have chosen
-a theme for each of the three modes. Then, once you restart kitty, it will
-automatically use your chosen themes depending on the OS color scheme.
-
-This works by creating three files: :file:`dark-theme.auto.conf`,
-:file:`light-theme.auto.conf` and :file:`no-preference-theme.auto.conf` in the
-kitty config directory. When these files exist, kitty queries the OS for its color scheme
-and uses the appropriate file. Note that the colors in these files override all other
-colors, and also all background image settings,
-even those specified using the :option:`kitty --override` command line flag.
-kitty will also automatically change colors when the OS color scheme changes,

-time the OS changes its color mode, any dynamic changes will be overridden.
-
-
-.. note::
-
-   On the GNOME desktop, the desktop reports the color preference as no-preference
-   when the "Dark style" is not enabled. So use :file:`no-preference-theme.auto.conf` to
-   select colors for light mode on GNOME. You can manually enable light style
-   with ``gsettings set org.gnome.desktop.interface color-scheme prefer-light``
-   in which case GNOME will report the color scheme as light and kitty will use
-   :file:`light-theme.auto.conf`.

+add_wrap_markers=False, alternate_screen=False)`` with which you can get the

+``window.child.pid`` is the PID of the processes that was launched
+in the window and ``window.id`` is the internal kitty ``id`` of the window.

-Miscellaneous protocol extensions
-==============================================
-
-These are a few small protocol extensions kitty implements, primarily for use
-by its own kitten, they are documented here for completeness.
-
-
-Simple save/restore of all terminal modes
---------------------------------------------
-
-XTerm has the XTSAVE/XTRESTORE escape codes to save and restore terminal
-private modes. However, they require specifying an explicit list of modes to
-save/restore. kitty extends this protocol to specify that when no modes are
-specified, all side-effect free modes should be saved/restored. By side-effects
-we mean things that can affect other terminal state such as cursor position or
-screen contents. Examples of modes that have side effects are: `DECOM
-<https://vt100.net/docs/vt510-rm/DECOM.html>`__ and `DECCOLM
-<https://vt100.net/docs/vt510-rm/DECCOLM.html>`__.
-
-This allows TUI applications to easily save and restore emulator state without
-needing to maintain lists of modes.
-
-
-Independent control of bold and faint SGR properties
--------------------------------------------------------
-
-In common terminal usage, bold is set via SGR 1 and faint by SGR 2. However,
-there is only one number to reset these attributes, SGR 22, which resets both.
-There is no way to reset one and not the other. kitty uses 221 and 222 to reset
-bold and faint independently.
-
-.. _mouse_leave_window:
-
-Reporting when the mouse leaves the window
-----------------------------------------------
-
-kitty extends the SGR Pixel mouse reporting protocol created by xterm to
-also report when the mouse leaves the window. This is event is delivered
-encoded as a normal SGR pixel event except that the eight bit is set on the
-first number. Additionally, bit 5 is set to indicate this is a motion related event.
-The remaining bits 1-7 (except 5) are used to encode button and modifier information.
-When bit 8 is set it means the event is a mouse has left the window event,
-and all other bits should be ignored. The pixel position values must also
-be ignored as they may not be accurate.
-
-An escape code to move the contents of the screen into the scrollback
--------------------------------------------------------------------------------------
-
-The escape code is ``\x1b [ 22 J`` (ignoring spaces present for clarity). It
-moves all screen contents (text and images) into the scrollback leaving the
-screen in the same state as it would be if the standard screen clear escape
-code had been used ``\x1b [ 2 J``.
-
-
-kitty specific private escape codes
----------------------------------------
-
-These are a family of escape codes used by kitty for various things including
-remote control. They are all DCS (Device Control String) escape codes starting
-with ``\x1b P @ kitty-`` (ignoring spaces present for clarity).

-The multiple cursors protocol
-==============================================
-
-.. versionadded:: 0.43.0
-
-.. warning::
-   This protocol is under public discussion in :iss:`8927`. It is subject to
-   change until that discussion is completed.
-
-Many editors support something called *multiple cursors* in which you can make
-the same changes at multiple locations in a file and the editor shows you
-cursors at each of the locations. In a terminal context editors typically
-implement this by showing some Unicode glyph at each location instead of the
-actual cursor. This is sub-optimal since actual cursors implemented by the
-terminal have many niceties like smooth animation [anim]_, auto adjust colors [rv]_,
-etc. To address this and other use cases, this protocol allows terminal programs to
-request that the terminal display multiple cursors at specific locations on the
-screen.
-
-Quickstart
-----------------
-
-An example, showing how to use the protocol:
-
-.. code-block:: sh
-
-    # Show cursors of the same shape as the main cursor at y=4, x=5
-    printf "\e[>29;2:4:5 q"
-    # Show more cursors on the seventh line, of various shapes, the underline shape is shown twice
-    printf "\e[>1;2:7:1 q\e[>2;2:7:3 q\e[>3;2:7:5;2:7:7 q"
-
-
-The escape code to show a cursor has the following structure (ignore spaces
-they are present for readability only)::
-
-    CSI > SHAPE;CO-ORD TYPE : CO-ORDINATES ; CO-ORD TYPE : CO-ORDINATES ... TRAILER
-
-Here ``CSI`` is the two bytes ESC (``0x1b``) and [ (``0x5b``). ``SHAPE`` can be
-one of:
-
-* ``0``: No cursor
-* ``1``: Block cursor
-* ``2``: Beam cursor
-* ``3``: Underline cursor
-* ``29``: Follow the shape of the main cursor
-* ``30``: Change the color of text under extra cursors
-* ``40``: Change the color of extra cursors
-* ``100``: Used for querying currently set cursors
-
-``CO-ORD TYPE`` can be one of:
-
-* ``0``: This refers to the position of the main cursor and has no following
-  co-ordinates.
-
-* ``2``: In this case the following co-ordinates are pairs of numbers pointing
-  to cells in the form ``y:x`` with the origin in the top left corner at
-  ``1,1``. There can be any number of pairs, the terminal must treat each pair
-  as a new location to set a cursor.
-
-* ``4``: In this case the following co-ordinates are sets of four numbers that
-  define a rectangle in the same co-ordinate system as above of the form:
-  ``top:left:bottom:right``. The shape is set on every cell in the rectangle
-  from the top left cell to the bottom right cell, inclusive. If no numbers
-  are provided, the rectangle is the full screen. There can be any number of
-  rectangles, the terminal must treat each set of four numbers as a new
-  rectangle.
-
-The sequence of ``CO-ORD TYPE : CO-ORDINATES`` can be repeated any number of
-times separated by ``;``. The ``SHAPE`` will be set on the cells indicated by
-each such group. For example: ``-1;2:3:4;4:5:6:7:8`` will set the shape ``-1``
-at the cell ``(3, 2)`` and in the rectangle ``(6, 5)`` to ``(8, 7)`` inclusive.
-
-Finally, the ``TRAILER`` terminates the sequence and is the bytes SPACE
-(``0x20``) and q (``0x71``).
-
-Terminals **must** ignore cells that fall outside the screen. That means, for
-rectangle co-ordinates only the intersection of the rectangle with the screen
-must be considered, and point co-ordinates that fall outside of the screen are
-simply ignored, with no effect.
-
-Terminals **must** ignore extra co-ordinates, that means if an odd number of
-co-ordinates are specified for type ``2`` the last co-ordinate is ignored.
-Similarly for type ``4`` if the number of co-ordinates is not a multiple of
-four, the last ``1 <= n <= 3`` co-ordinates are ignored, as if they were not
-specified.
-
-Querying for support
--------------------------
-
-A terminal program can query the terminal emulator for support of this
-protocol by sending the escape code::
-
-    CSI > TRAILER
-
-In this case a supporting terminal must reply with::
-
-    CSI > 1;2;3;29;30;40;100;101 TRAILER
-
-Here, the list of numbers indicates the cursor shapes and other operations
-the terminal supports and can be any subset of the above. No numbers
-indicates the protocol is not supported. To avoid having to wait with a
-timeout for a response from the terminal, the client should send this
-query code immediately followed by a request for the
-`primary device attributes <https://vt100.net/docs/vt510-rm/DA1.html>`_.
-If the terminal responds with an answer for the device attributes without
-an answer for the *query* the terminal emulator does not support this protocol at all.
-
-Terminals **must** respond to these queries in FIFO order, so that
-multiplexers that split a single screen know which split to send responses too.
-
-Clearing previously set multi-cursors
-------------------------------------------
-
-The cursor at a cell is cleared by setting its shape to ``0``.
-The most common operation is to clear all previously set multi-cursors. This is
-easily done using the *rectangle* co-ordinate system above, like this::
-
-    CSI > 0;4 TRAILER
-
-For more precise control different co-ordinate types can be used. This is
-particularly important for multiplexers that split up the screen and therefore
-need to re-write these escape codes.
-
-.. _extra_cursor_color:
-
-Changing the color of extra cursors
----------------------------------------
-
-In order to visually distinguish extra cursors from the main cursor, it is
-possible to specify a color pair for extra cursors. Note that for performance
-reasons, there is only a single color pair that all extra cursors share.
-The color pair consists of the cursor color and the color for text in the cell
-the cursor is on.
-
-To change this color pair use an escape code of the form::
-
-    CSI > WHICH ; COLOR_SPACE : COLOR_PARAMETER1 : COLOR_PARAMETER2 : ... TRAILER
-
-Here, ``WHICH`` is ``30`` to set the color of text under the cursor and ``40``
-to set the color of the cursor itself (these numbers mimic the SGR codes for
-foreground and background respectively).
-
-The ``COLOR_SPACE`` parameter sets the type of color, it can take values:
-
-``0`` - unset color is same as for main cursor. No color parameters.
-``1`` - *special* which typically means some kind of reverse video effect, see below
-``2`` - sRGB color, with three color parameters, red, green and blue as numbers
-from 0 to 255
-``5`` - Indexed color with one color parameter which is an index into the color
-table from 0 to 255
-
-When the cursor color is set to *special* via ``40`` it means the block cursor
-must be rendered with a reverse video effect where the cursor color becomes the
-foreground color of the cell under the cursor and the foreground color of the
-cell becomes its background color. Implementations are free to adjust these
-colors to ensure suitable contrast levels. In this case the text color set by
-``30`` must be ignored.
-
-When the cursor color is not set to *special* but the text color via ``30`` is
-set to special, then that means the foreground color of the cell with the
-cursor must be changed to its background color for a partial reverse video
-effect.
-
-When unset, aka, set to ``0`` the cursors must be the same color as the main
-cursor. In particular if the main color is using a reverse video effect, the
-extra cursors must use the exact same colors as the main cursor, not the colors
-of the cells they are on.
-
-Querying for already set cursors
---------------------------------------
-
-Programs can ask the terminal what extra cursors are currently set, by sending
-the escape code::
-
-    CSI > 100 TRAILER
-
-The terminal must respond with **one** escape code::
-
-    CSI > 100; SHAPE:CO-ORDINATE TYPE:CO-ORDINATES ; ... TRAILER
-
-Here, the ``SHAPE:CO-ORDINATE TYPE:CO-ORDINATES`` block can be repeated any
-number of times, separated by ``;``. This response gives the set of shapes and
-positions currently active. If no cursors are currently active, there will be
-no blocks, just an empty response of the form::
-
-    CSI > 100 TRAILER
-
-Again, terminals **must** respond in FIFO order so that multiplexers know where
-to direct the responses.
-
-Querying for extra cursor colors
--------------------------------------
-
-Programs can ask the terminal what cursor colors are currently set, by sending
-escape code::
-
-    CSI > 101 TRAILER
-
-The terminal must respond with **one** escape code::
-
-    CSI > 101 ; 30 : COLOR_SPACE : COLOR_PARAMETERS ; 40 : COLOR_SPACE : COLOR_PARAMETERS TRAILER
-
-The number and type of ``COLOR_PARAMETERS`` depends on the preceding
-``COLOR_SPACE`` and can be omitted for some ``COLOR_SPACE`` values. See the
-section :ref:`extra_cursor_color` for details.
-
-
-Interaction with other terminal controls and state
--------------------------------------------------------
-
-**The main cursor**
-    The extra cursors must all have the same color and opacity and blink state
-    as the main cursor. The main cursor's visibility must not affect the
-    visibility of the extra cursors. Their visibility and shape are controlled
-    only by this protocol.
-
-**Clearing the screen**
-    The escape codes used to clear the screen (`ED <https://vt100.net/docs/vt510-rm/ED.html>`__)
-    with parameters 2, 3 and 22 must remove all extra cursors,
-    this is so that the clear command can be used by users to clear the screen of extra cursors.
-
-**Reset***
-    This must remove all extra cursors.
-
-**Alternate screen***
-    Switching between the main and alternate screens must remove all extra
-    cursors.

-**Scrolling**
-    The index (IND) and reverse index (RI) escape codes that cause screen
-    contents to scroll into scrollback or off screen must not affect
-    the extra cursors in any way. They remain at exactly the same position.
-    It is up to applications to manage extra cursor positions when using these
-    escape codes if needed. There are not a lot of use cases for scrolling
-    extra cursors with screen content, since extra cursors are meant to be
-    ephemeral and on screen only, not in scrollback. This allows terminals
-    to avoid the extra overhead of adjusting positions of the extra cursors
-    on every scroll.

-   <cursor_blink_interval>` using any CSS easing function. This cannot be
-   implemented using fake cursors.
-
-.. [rv] kitty has a special "reverse video" color mode for cursors where the
-   color of the cursor and the text under the cursor is adjusted based on the
-   color of the cell under the cursor. This also cannot be implemented using

-Sessions
-=============
-
-kitty has robust support for sessions. A session is basically a simple text
-file where you can define kitty windows, tabs and what programs to run in them
-as well as how to layout the windows. kitty also supports actions to easily
-:ac:`create and switch between existing sessions <goto_session>`, so that you
-can move seamlessly from working on one project to another with a couple of keystrokes.
-
-Let's see a quick example to get a feel of how easy it is to create sessions. First,
-a session file to develop a project:
-
-.. code-block:: session
-
-    # Set the layout for the current tab
-    layout tall
-    # Set the working directory for windows in the current tab
-    cd ~/path/to/myproject
-    # Create the "main" window and run an editor in it to edit the project files
-    launch --title "Edit My Project" /usr/bin/nvim
-    # Create a side window to run a shell to build or test project
-    launch --title "Build My Project"
-    # Create another side window to keep an eye on some useful log file
-    launch --title "Log for my project" /usr/bin/tail -f /path/to/project/log/file
-
-Save this file as :file:`~/path/to/myproject/launch.kitty-session`. Now when
-you want to work on the project, simply run:
-
-.. code-block:: sh
-
-    kitty --session ~/path/to/myproject/launch.kitty-session
-
-You can also set the session in :file:`kitty.conf` via :opt:`startup_session`.
-
-Thus, it is very easy to create sessions and work on projects. To learn how to
-create more complex sessions, see :ref:`complex_sessions`.
-
-
-.. _goto_session:
-
-Creating/Switching to sessions with a keypress
-------------------------------------------------
-
-If you like to manage multiple sessions within a single terminal and
-easily swap between them, kitty has you covered. You can use the
-:ac:`goto_session` action in kitty.conf, like this:
-
-.. code-block:: conf
-
-   # Press F7 and then c to jump to the "cool" project
-   map f7>c goto_session ~/path/to/cool/cool.kitty-session
-   # Press F7 and then h to jump to the "hot" project
-   map f7>h goto_session ~/path/to/hot/hot.kitty-session
-   # Browse and select from the list of known projects defined via goto_session commands
-   map f7>/ goto_session
-   # Same as above, but the sessions are listed alphabetically instead of by most recent
-   map f7>/ goto_session --sort-by=alphabetical
-   # Go to the previously active session (larger negative numbers jump further back in history)
-   map f7>- goto_session -1
-
-In this manner you can define as many projects/sessions as you like and easily
-switch between them with a keypress.
-
-You can also close sessions using the :ac:`close_session` action, which closes
-all windows in the session with a single keypress.
-
-
-Displaying the currently active session name
-----------------------------------------------
-
-You can display the name of the currently active session file in the kitty tab
-bar using :opt:`tab_title_template`. For example, using the value::
-
-    {session_name} {title}
-
-will show you the name of the session file the current tab was loaded from, as
-well as the normal tab title. Or alternatively, you can set the tab title
-directly to a project name in the session file itself when creating the tab,
-like this::
-
-    new_tab My Project Name
-
-.. _complex_sessions:
-
-More complex sessions
--------------------------
-
-If you want to create more complex sessions, with sophisticated layouts, such
-as :ref:`splits_layout`, the easiest way is to set up the state you want to
-save manually by first starting kitty like this:
-
-.. code-block:: sh
-
-    kitty -o 'map f1 save_as_session --use-foreground-process --relocatable'
-
-Now create whatever splits and tabs you need and start whatever programs such
-as editors, REPLs, debuggers, etc. you want to start in each of them. Once
-kitty is the way you want it, press the :kbd:`F1` key, and you will be prompted
-for a path at which to save the session file. Specify the path and the session
-will be saved there with the exact setup you created. The saved file will even
-be opened in your editor for you to review, automatically.
-
-.. tip::
-   If you want session files to be saved to a specific directory regardless of
-   your current working directory, use the ``--base-dir`` option. For example::
-
-       map f7>s save_as_session --use-foreground-process --base-dir ~/.local/share/kitty/sessions
-
-   This is particularly useful when kitty is launched from system-wide shortcuts
-   where the working directory might not be your home directory. Note that
-   ``--relocatable`` is typically not used with ``--base-dir``, since relocatable
-   is meant for session files that are co-located with their project directories.
-
-If instead, you want to create these by hand, see the example below which shows
-all the major keywords you can use in kitty session files:
-
-.. code-block:: session
-
-    # Set the layout for the current tab
-    layout tall
-    # Set the working directory for windows in the current tab. Relative paths

-
-Making newly created windows join an existing session
----------------------------------------------------------
-
-Normally, after activating a session, if you create new windows/tabs
-they don't belong to the session. If you would prefer to have them belong
-to the currently active session, you can use the :ac:`new_window_with_cwd`
-and :ac:`new_tab_with_cwd` actions instead, like this::
-
-    map kitty_mod+enter new_window_with_cwd
-    map kitty_mod+t new_tab_with_cwd
-    map kitty_mod+n new_os_window_with_cwd
-
-This will cause newly created windows and tabs to belong to the currently active
-session, if any. Note that adding a window to a session in this way is
-temporary, it does not edit the session file. If you wish to update the
-session file of the currently active session, you can use the following
-mapping for it::
-
-    map f5 save_as_session --relocatable --use-foreground-process --match=session:. .
-
-The two can be combined, using the :ac:`combine` action.
-For even more control of what session a window is added to use
-the :doc:`launch <launch>` command with the :option:`launch --add-to-session`
-flag.
-
-
-Sessions with remote connections
--------------------------------------
-
-If you use the :doc:`ssh kitten </kittens/ssh>` to connect to remote computers,
-:ac:`save_as_session` is smart enough to save the ssh kitten invocation to your
-session file, preserving the remote working directory and even the currently
-running program on the remote host! Try it, run kitty with::
-
-    kitty -o 'map f1 save_as_session --use-foreground-process --relocatable' --session <(echo "layout vertical\nlaunch\nlaunch")
-
-Now in both windows, run::
-
-    kitten ssh localhost
-
-To connect them both to a remote computer (replace ``localhost`` with another
-computer if you like). In one window change the directory to /tmp and in the
-other start some program. Then press :kbd:`F1` to save the session file.
-When you run the session file in another kitty instance you will see both
-windows re-created, as expected with the correct working directories and
-running programs.
-
-Managing multi tab sessions in a single OS Window
-----------------------------------------------------
-
-The natural way to organise sessions in kitty is one per :term:`os_window`.
-However, if you prefer to manage multiple sessions in a single OS Window, you
-can configure the kitty tab bar to only show tabs that belong to the currently
-active session. To do so, use :opt:`tab_bar_filter` in :file:`kitty.conf` set::
-
-    tab_bar_filter session:~ or session:^$
-
-This will restrict the tab bar to only showing tabs from the currently active
-session as well tabs that do not belong to any session. Furthermore, when you
-are in a window or tab that does not belong to any session, the tab bar will
-show the tabs from the most recent active session, to maintain context.
-
-Keyword reference
----------------------
-
-Below is the list of all supported keywords in session files along with
-documentation for them.
-
-``cd [path]``
-    Change the working directory for all windows in the current tab to
-    ``path``. Relative paths are resolved with respect to the directory
-    containing the session file.
-
-``focus``
-    Give keyboard focus to the window created by the previous launch command
-
-``focus_matching_window``
-    Give keyboard focus to window that matches the specified expression. See
-    :ref:`search_syntax` for the syntax for matching expressions.
-
-``focus_os_window``
-    Give keyboard focus to the current OS Window. This is guaranteed to work
-    only is some other OS Window in the current kitty process has focus,
-    otherwise the window manager might block changing focus to prevent *focus
-    stealing*.
-
-``focus_tab [tab specifier]``
-    Set which tab should be active (focused) in the current OS Window. The tab
-    specifier can be either a plain number (treated as a 0-based index) or a
-    match expression. For example, ``focus_tab 0`` will focus the first tab,
-    ``focus_tab 1`` the second tab, and ``focus_tab title:logs`` will focus the
-    tab whose title matches "logs". See :ref:`search_syntax` for the full syntax
-    of match expressions. This is useful for session files that create multiple
-    tabs and want to ensure a specific tab is active when the session is loaded.
-
-``enabled_layouts comma separated list of layout names``
-    Set the layouts allowed in the current tab. Same syntax as
-    :opt:`enabled_layouts`.
-
-``launch``
-    Create a new window running the specified command or the default shell if
-    no command is specified. See :doc:`launch` for details. Note that creating
-    tabs and OS Windows using launch is not supported in session files, use the
-    dedicated keywords for these.
-
-``layout name``
-    Set the layout for the current tab to the specified layout, including any
-    specified options, see :doc:`layouts` for the available alyouts and
-    options.
-
-``new_os_window``
-    Create a new OS Window. Any OS window related keywords specified before the
-    first ``new_os_window`` will apply to the first OS Window.
-
-``new_tab [tab title]``
-    Create a new tab with the specified title. If no title is specified, the
-    title behaves just as for a regular tab in kitty.
-
-``os_window_title``
-    Set the title for the current OS Window. The OS Window will then always
-    have this title, it will not change based on the title of the currently active
-    window inside the OS Window.
-
-``os_window_class``
-    Set the class part of WM_CLASS or Wayland Application Id for the current OS Window
-
-``os_window_name``
-    Set the name part of WM_CLASS or Wayland Window tag for the current OS Window
-
-``os_window_size``
-    Set the size of the current OS Window, can be specified in pixels or cells.
-    For example: 80c 24c is a window of width 80 cells by 24 cells.
-
-``os_window_state``
-    Set the state of the current OS Window, can be: ``normal``, ``fullscreen``, ``maximized`` or ``minimized``
-
-``resize_window``
-    Resize the current window. See the :ac:`resize_window` action for details.
-    For example: resize_window wider 2
-
-``set_layout_state``
-    This keyword is only used in session files generated by the
-    :ac:`save_as_session` action, it's syntax is undocumented and for internal
-    use only.
-
-``title``
-    Set the title for the next window. Deprecated, use ``launch --title``
-    instead.
-
-
-.. _save_as_session:
-
-The save_as_session action
-------------------------------
-
-This action can be mapped to a key press in :file:`kitty.conf`. It will save
-the currently open OS Windows, tabs, windows, running programs, working
-directories, etc. into a session file. It is a convenient way to
-:ref:`complex_sessions`. The options this action takes are documented below.

-The text sizing protocol
-==============================================
-
-.. versionadded:: 0.40.0
-
-Classically, because the terminal is a grid of equally sized characters, only
-a single text size was supported in terminals, with one minor exception, some
-characters were allowed to be rendered in two cells, to accommodate East Asian
-square aspect ratio characters and Emoji. Here, by single text size we mean the
-font size of all text on the screen is the same.
-
-This protocol allows text to be displayed in the terminal in different sizes
-both larger and smaller than the base text. It also solves the long standing
-problem of robustly determining the width (in cells) a character should have.
-Applications can interleave text of different sizes on the screen allowing for
-typographic niceties like headlines, superscripts, etc.
-
-Note that this protocol is fully backwards compatible, terminals that implement
-it will continue to work just the same with applications that do not use it.
-Because of this, it is not fully flexible in the font sizes it allows, as it
-still has to work with the character cell grid based fundamental nature of the
-terminal. Public discussion of this protocol is :iss:`here <8226>`.
-
-Quickstart
---------------
-
-Using this protocol to display different sized text is very simple, let's
-illustrate with a few examples to give us a flavor:
-
-.. code-block:: sh
-
-   printf "\e]_text_size_code;s=2;Double sized text\a\n\n"
-   printf "\e]_text_size_code;s=3;Triple sized text\a\n\n\n"
-   printf "\e]_text_size_code;n=1:d=2;Half sized text\a\n"
-
-Note that the last example, of half sized text, has half height characters, but
-they still each take one cell, this can be fixed with a little more work:
-
-.. code-block:: sh
-
-   printf "\e]_text_size_code;n=1:d=2:w=1;Ha\a\e]66;n=1:d=2:w=1;lf\a\n"
-
-The ``w=1`` mechanism allows the program to tell the terminal what width the text
-should take. This not only fixes using smaller text but also solves the long
-standing terminal ecosystem bugs caused by the client program not knowing how
-many cells the terminal will render some text in.
-
-
-The escape code
------------------
-
-There is a single escape code used by this protocol. It is sent by client
-programs to the terminal emulator to tell it to render the specified text
-at the specified size. It is an ``OSC`` code of the form::
-
-    <OSC> _text_size_code ; metadata ; text <terminator>
-
-Here, ``OSC`` is the bytes ``ESC ] (0x1b 0x5b)``. The ``metadata`` is a colon
-separated list of ``key=value`` pairs. The final part of the escape code is the
-text which is simply plain text encoded as :ref:`safe_utf8`, the text must be
-no longer than ``4096`` bytes. Longer strings than that must be broken up into
-multiple escape codes. Spaces in this definition are for clarity only and
-should be ignored. The ``terminator`` is either the byte ``BEL (0x7)`` or the
-bytes ``ESC ST (0x1b 0x5c)``.
-
-There are only a handful of metadata keys, defined in the table below:
-
-
-.. csv-table:: The text sizing metadata keys
-   :header: "Key", "Value", "Default", "Description"
-
-    "s", "Integer from 1 to 7",  "1", "The overall scale, the text will be rendered in a block of ``s * w`` by ``s`` cells"
-
-    "w", "Integer from 0 to 7",  "0", "The width, in cells, in which the text should be rendered. When zero, the terminal should calculate the width as it would for normal text, splitting it up into scaled cells."
-
-    "n", "Integer from 0 to 15", "0", "The numerator for the fractional scale."
-
-    "d", "Integer from 0 to 15", "0", "The denominator for the fractional scale. Must be ``> n`` when non-zero."
-
-    "v", "Integer from 0 to 2",  "0", "The vertical alignment to use for fractionally scaled text. ``0`` - top, ``1`` - bottom, ``2`` - centered"
-
-    "h", "Integer from 0 to 2",  "0", "The horizontal alignment to use for fractionally scaled text. ``0`` - left, ``1`` - right, ``2`` - centered"
-
-
-How it works
-------------------
-
-This protocol works by allowing the client program to tell the terminal to
-render text in multiple cells. The terminal can then adjust the actual font
-size used to render the specified text as appropriate for the specified space.
-
-The space to render is controlled by four metadata keys, ``s (scale)``, ``w (width)``, ``n (numerator)``
-and ``d (denominator)``. The most important are the ``s`` and ``w`` keys. The text
-will be rendered in a block of ``s * w`` by ``s`` cells. A special case is ``w=0``
-(the default), which means the terminal splits up the text into cells as it
-would normally without this protocol, but now each cell is an ``s by s`` block of
-cells instead. So, for example, if the text is ``abc`` and ``s=2`` the terminal would normally
-split it into three cells::
-
-    │a│b│c│
-
-But, because ``s=2`` it instead gets split as::
-
-    │a░│b░│c░│
-    │░░│░░│░░│
-
-The terminal multiplies the font size by ``s`` when rendering these
-characters and thus ends up rendering text at twice the base size.
-
-When ``w`` is a non-zero value, it specifies the width in scaled cells of the
-following text. Note that **all** the text in that escape code must be rendered
-in ``s * w`` cells. When both ``s`` and ``w`` are present, the resulting multicell
-contains all the text in the escape code rendered in a grid of ``(s * w, s)``
-cells, i.e. the multicell is ``s*w`` cells wide and ``s`` cells high.
-
-If the text does not fit, the terminal is free to do whatever it
-feels is best, including truncating the text or downsizing the font size when
-rendering it. It is up to client applications to use the ``w`` key wisely and not
-try to render too much text in too few cells. When sending a string of text
-with non zero ``w`` to the terminal emulator, the way to do it is to split up the
-text into chunks that fit in ``w`` cells and send one escape code per chunk. So
-for the string: ``cool-🐈`` the actual escape codes would be (ignoring the header
-and trailers)::
-
-   w=1;c w=1;o w=1;o w=1;l w=1;- w=2:🐈
-
-Note, in particular, how the last character, the cat emoji, ``🐈`` has ``w=2``.
-In practice client applications can assume that terminal emulators get the
-width of all ASCII code points correct and use the ``w=0`` form for efficient
-transmission, so that the above becomes::
-
-   cool- w=2:🐈
-
-The use of non-zero ``w`` should mainly be restricted to non-ASCII characters and
-when using fractional scaling, as described below.
-
-.. note:: Text sizes specified by scale are relative to the base font size,
-   thus if the base font size is changed, these sizes are changed as well.
-   So if the terminal emulator is using a base font size of ``11pt``, then
-   ``s=2`` will be rendered in approximately ``22pt`` (approx. because the
-   terminal may need to slightly adjust font size to ensure it fits as not all
-   fonts scale sizes linearly). If the user changes the base font size of the
-   terminal emulator to ``12pt`` then the scaled font size becomes ``~24pt``
-   and so on.
-
-
-Fractional scaling
-^^^^^^^^^^^^^^^^^^^^^^^
-
-Using the main scale parameter (``s``) gives us only 7 font sizes. Fortunately,
-this protocol allows specifying fractional scaling, fractional scaling is
-applied on top of the main scale specified by ``s``. It allows niceties like:
-
-* Normal sized text but with half a line of blank space above and half a line below (``s=2:n=1:d=2:v=2``)
-* Superscripts (``n=1:d=2``)
-* Subscripts (``n=1:d=2:v=1``)
-* ...
-
-The fractional scale **does not** affect the number of cells the text occupies,
-instead, it just adjusts the rendered font size within those cells.
-The fraction is specified using an integer numerator and denominator (``n`` and
-``d``). In addition, by using the ``v`` key one can vertically align the
-fractionally scaled text at top, bottom or middle. Similarly, the ``h`` key
-does horizontal alignment — left, right or centered.
-
-When using fractional scaling one often wants to fit more than a single
-character per cell. To accommodate that, there is the ``w`` key. This specifies
-the number of cells in which to render the text. For example, for a superscript
-one would typically split the string into pairs of characters and use the
-following for each pair::
-
-    OSC _text_size_code ; n=1:d=2:w=1 ; ab <terminator>
-    ... repeat for each pair of characters
-
-
-Fixing the character width issue for the terminal ecosystem
----------------------------------------------------------------------
-
-Terminals create user interfaces using text displayed in a cell grid. For
-terminal software that creates sophisticated user interfaces it is particularly
-important that the client program running in the terminal and the terminal
-itself agree on how many cells a particular string should be rendered in. If
-the two disagree, then the entire user interface can be broken, leading to
-catastrophic failures.
-
-Fundamentally, this is a co-ordination problem. Both the client program and the
-terminal have to somehow share the same database of character properties and
-the same algorithm for computing string lengths in cells based on that shared
-database. Sadly, there is no such shared database in reality. The closest we
-have is the Unicode standard. Unfortunately, the Unicode standard has a new
-version almost every year and actually changes the width assigned to some
-characters in different versions. Furthermore, to actually get the "correct"
-width for a string using that standard one has to do grapheme segmentation,
-which is a :ref:`complex algorithm, specified below <gseg>`.
-Expecting all terminals and all terminal programs to have both up-to-date
-character databases and a bug free implementation of this algorithm is not
-realistic.
-
-So instead, this protocol solves the issue robustly by removing the
-co-ordination problem and putting only one actor in charge of determining
-string width. The client becomes responsible for doing whatever level of
-grapheme segmentation it is comfortable with using whatever Unicode database is
-at its disposal and then it can transmit the segmented string to the terminal
-with the appropriate ``w`` values so that the terminal renders the text in the
-exact number of cells the client expects.
-
-.. note::
-   It is possible for a terminal to implement only the width part of this spec
-   and ignore the scale part. This escape code works with only the `w` key as
-   well, as a means of specifying how many cells each piece of text occupies.
-   In such cases ``s`` defaults to 1.
-   See the section on :ref:`detect_text_sizing` on how client applications can
-   query for terminal emulator support.
-
-
-Wrapping and overwriting behavior
--------------------------------------
-
-If the multicell block (``s * w by s`` cells) is larger than the screen size in either
-dimension, the terminal must discard the character. Note that in particular
-this means that resizing a terminal screen so that it is too small to fit a
-multicell character can cause the character to be lost.
-
-When drawing a multicell character, if wrapping is enabled (DECAWM is set) and
-the character's width (``s * w``) does not fit on the current line, the cursor is
-moved to the start of the next line and the character is drawn there.
-If wrapping is disabled and the character's width does not fit on the current
-line, the cursor is moved back as far as needed to fit ``s * w`` cells and then
-the character is drawn, following the overwriting rules described below.
-
-When drawing text either normal text or text specified via this escape code,
-and this text would overwrite an existing multicell character, the following
-rules must be followed, in decreasing order of precedence:
-
-#. If the text is a combining character it is added to the existing multicell
-   character
-#. If the text will overwrite the top-left cell of the multicell character, the
-   entire multicell character must be erased
-#. If the text will overwrite any cell in the topmost row of the multicell
-   character, the entire multicell character must be replaced by spaces (this
-   rule is present for backwards compatibility with how overwriting works for
-   wide characters)
-#. If the text will overwrite cells from a row after the first row, then cursor should be moved past the
-   cells of the multicell character on that row and only then the text should be
-   written. Note that this behavior is independent of the value of DECAWM. This
-   is done for simplicity of implementation.
-
-The skipping behavior of the last rule can be complex requiring the terminal to
-skip over lots of cells, but it is needed to allow wrapping in the presence of
-multicell characters that extend over more than a single line.
-
-.. _detect_text_sizing:
-
-Detecting if the terminal supports this protocol
------------------------------------------------------
-
-To detect support for this protocol use the `CPR (Cursor Position Report)
-<https://vt100.net/docs/vt510-rm/CPR.html>`__ escape code. Send a ``CR``
-(carriage return) followed by ``CPR`` followed by ``\e]_text_size_code;w=2; \a``
-which will draw a space character in two cells, followed by another ``CPR``.
-Then send ``\e]_text_size_code;s=2; \a`` which will draw a space in a ``2 by 2``
-block of cells, followed by another ``CPR``.
-
-Then wait for the three responses from the terminal to the three CPR queries.
-If the cursor position in the three responses is the same, the terminal does
-not support this protocol at all, if the second response has the cursor
-moved by two cells, then the width part is supported and if the third response has the
-cursor moved by another two cells, then the scale part is supported.
-
-
-Interaction with other terminal controls
---------------------------------------------------
-
-This protocol does not change the character grid based nature of the terminal.
-Most terminal controls assume one character per cell so it is important to
-specify how these controls interact with the multicell characters created by
-this protocol.
-
-Cursor movement
-^^^^^^^^^^^^^^^^^^^
-
-Cursor movement is unaffected by multicell characters, all cursor movement
-commands move the cursor position by single cell increments, as has always been
-the case for terminals. This means that the cursor can be placed at any
-individual single cell inside a larger multicell character.
-
-When a multicell character is created using this protocol, the cursor moves
-`s * w` cells to the right, in the same row it was in.
-
-Terminals *should* display a large cursor covering the entire multicell block
-when the actual cursor position is on any cell within the block. Block cursors
-cover all the cells of the multicell character, bar cursors appear in all the
-cells in the first column of the character and so on.
-
-
-Editing controls
-^^^^^^^^^^^^^^^^^^^^^^^^^
-
-There are many controls used to edit existing screen content such as
-inserting characters, deleting characters and lines, etc. These were all
-originally specified for the one character per cell paradigm. Here we specify
-their interactions with multicell characters.
-
-**Insert characters** (``CSI @`` aka ``ICH``)
-    When inserting ``n`` characters at cursor position ``x, y`` all characters
-    after ``x`` on line ``y`` are supposed to be right shifted. This means
-    that any multi-line character that intersects with the cells on line ``y`` at ``x``
-    and beyond must be erased. Any single line multicell character that is
-    split by the cells at ``x`` and ``x + n - 1`` must also be erased.
-
-**Delete characters** (``CSI P`` aka ``DCH``)
-    When deleting ``n`` characters at cursor position ``x, y`` all characters
-    after ``x`` on line ``y`` are supposed to be left shifted. This means
-    that any multi-line character that intersects with the cells on line ``y`` at ``x``
-    and beyond must be erased. Any single line multicell character that is
-    split by the cells at ``x`` and ``x + n - 1`` must also be erased.
-
-**Erase characters** (``CSI X`` aka ``ECH``)
-    When erasing ``n`` characters at cursor position ``x, y`` the ``n`` cells
-    starting at ``x`` are supposed to be cleared. This means that any multicell
-    character that intersects with the ``n`` cells starting at ``x`` must be
-    erased.
-
-**Erase display** (``CSI J`` aka ``ED``)
-    Any multicell character intersecting with the erased region of the screen
-    must be erased. When using mode ``22`` the contents of the screen are first
-    copied into the history, including all multicell characters.
-
-**Erase in line** (``CSI K`` aka ``EL``)
-    Works just like erase characters above. Any multicell character
-    intersecting with the erased cells in the line is erased.
-
-**Insert lines** (``CSI L`` aka ``IL``)
-    When inserting ``n`` lines at cursor position ``y`` any multi-line
-    characters that are split at the line ``y`` must be erased. A split happens
-    when the second or subsequent row of the multi-line character is on the line
-    ``y``. The insertion causes ``n`` lines to be removed from the bottom of
-    the screen, any multi-line characters are split at the bottom of the screen
-    must be erased. A split is when any row of the multi-line character except
-    the last row is on the last line of the screen after the insertion of ``n``
-    lines.
-

-The algorithm for splitting text into cells
-------------------------------------------------
-
-.. note::
-   kitty comes with a utility to test terminal compliance with this algorithm.
-   Install kitty and run: ``kitten __width_test__`` in any terminal to test it.
-   This uses tests published by the Unicode consortium, `GraphemeBreakTest.txt
-   <https://www.unicode.org/Public/UCD/latest/ucd/auxiliary/GraphemeBreakTest.txt>`__.
-
-.. warning::
-   This algorithm is under public discussion in :iss:`8533`. If serious issues
-   are brought to light in that discussion, there may be small changes to the
-   algorithm to address them. Additionally, in the future if the Unicode standard
-   changes in ways that affect this algorithm, it will be updated. Currently the
-   algorithm is based on Unicode version 16.
-
-Here, we specify how a terminal must split up text into cells, where a cell is
-a width one unit in the character grid the terminal displays.
-
-The basis for the algorithm is the
-`Grapheme segmentation algorithm <https://www.unicode.org/reports/tr29/#Grapheme_Cluster_Boundaries>`__
-from the Unicode standard. However, that algorithm alone is insufficient to
-fully specify text handling for terminals. The full algorithm is specified below.
-
-A terminal using this algorithm must decode the bytes they receive
-into Unicode scalar values (i.e., code points except surrogates) using UTF-8.
-When it encounters any UTF-8 ill-formed subsequences,
-it must be replace each
-`maximal subpart of the ill-formed subsequence <https://www.unicode.org/versions/Unicode16.0.0/core-spec/chapter-3/#G66453>`__
-with a :code:`U+FFFD REPLACEMENT CHARACTER` (<28>).
-
-For each decoded code point:
-
-#. First check if the code point is an ASCII control code, and handle it
-   appropriately. ASCII control codes are the code points less than :code:`U+0032` and the
-   code point :code:`U+0127 DEL`. The code point :code:`U+0000 NUL` must be discarded.
-
-#. Next, check if the code point is *invalid*, and if it is, discard it
-   and finish processing. Invalid code points are code points with Unicode category :code:`Cc or Cs`
-   and 66 additional code points: :code:`[0xfdd0, 0xfdef]`, :code:`[0xfffe, 0x10ffff-1, 0x10000]`
-   and :code:`[0xffff, 0x10ffff, 0x10000]`.
-
-#. Next, check if there is a previous cell before the
-   current cursor position. This means either the cursor is at x > 0 in which
-   case the previous cell is at x-1 on the same line, or the previous cell is
-   the last cell of the previous line, provided there is no line break
-   between the previous and current lines.
-
-#. Next, calculate the width in cells of the received code point,
-   which can be 0, 1, or 2 depending on the code point properties in
-   the Unicode standard.
-
-#. If there is no previous cell and the code point's width is zero,
-   the code point is discarded and its processing is finished.
-
-#. If there is a previous cell, the
-   `Grapheme segmentation algorithm UAX29-C1-1 <https://www.unicode.org/reports/tr29/#C1-1>`__
-   is used to determine if there is a grapheme boundary between the previous cell
-   and the current code point.
-
-#. If there is no boundary, the current code point is added to the previous
-   cell and processing of the code point is finished. See the :ref:`var_select`
-   section below for handling of Unicode Variation selectors.
-
-#. If there is a boundary, but the width of the current code point is zero,
-   it is added to the previous cell and processing is finished.
-
-#. The code point is added to the current cell and the cursor is moved forward
-   (right) by either 1 or 2 cells depending on the width of the code point.
-
-
-It remains to specify how to calculate the width in cells of a code point.
-To do this, code points are divided into various classes, as
-described by the rules below, in order of decreasing priority:
-
-.. note::
-   Notation: :code:`[start, stop, step]` means the integers from :code:`start`
-   to :code:`stop` in increments of :code:`step`. When the step is not
-   specified, it defaults to one.
-
-#. *Regional indicators*: 26 code points starting at :code:`0x1F1E6`. These all
-   have width 2
-
-#. *Doublewidth*: Parse `EastAsianWidth.txt
-   <https://www.unicode.org/Public/UCD/latest/ucd/EastAsianWidth.txt>`__ from
-   the Unicode standard. All code points marked :code:`W` or :code:`F` have
-   width two. All code points in the following ranges have width two *unless*
-   they are marked as :code:`A` in :code:`EastAsianWidth.txt`: :code:`[0x3400,
-   0x4DBF], [0x4E00, 0x9FFF], [0xF900, 0xFAFF], [0x20000, 0x2FFFD], [0x30000, 0x3FFFD]`
-
-#. *Wide emoji*: Parse `emoji-sequences.txt
-   <https://www.unicode.org/Public/emoji/latest/emoji-sequences.txt>`__ from
-   the Unicode standard. All :code:`Basic_Emoji` have width two unless they are
-   followed by :code:`FE0F` in the file. The leading copdepoints in all
-   :code:`RGI_Emoji_Modifier_Sequence` and :code:`RGI_Emoji_Tag_Sequence` have width two.
-   All code points in :code:`RGI_Emoji_Flag_Sequence` have width two.
-
-#. *Marks*: These are all zero width code points. They are code points with Unicode
-   categories whose first letter is :code:`M` or :code:`S`. Additionally,
-   code points with Unicode category: :code:`Cf`. Finally, they include
-   all modifier code points from :code:`RGI_Emoji_Modifier_Sequence` in the
-   *Wide emoji* rule above.
-
-#. All remaining code points have a width of one cell.
-
-.. _var_select:
-
-Unicode variation selectors
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-There are two code points (:code:`U+FE0E` and :code:`U+FE0F`) that can actually
-alter the width of the previous code point. When adding a code point to the
-previous cell these have to be handled specially.
-
-``U+FE0E`` - Variation Selector 15
-  When the previous cell has width two and the last code point in the previous
-  cell is one of the ``Basic_Emoji`` code points from the *Wide emoji* rule above
-  that is *not* followed by ``FEOF`` then the width of the previous cell is
-  decreased to one.
-
-``U+FE0F`` - Variation Selector 16
-  When the previous cell has width one and the last code point in the previous
-  cell is one of the ``Basic_Emoji`` code points from the *Wide emoji* rule above
-  that is followed by ``FEOF`` then the width of the
-  previous cell is increased to two.
-
-Note that the rule for ``U+FE0E`` is particularly problematic for terminals as
-it means that the width of a string cannot be determined without knowing the
-width of the screen it will be rendered on. This is because when there is only
-one cell left on the current line and a wide emoji is received it wraps onto
-the next line. If subsequently a ``U+FE0E`` is received, the emoji becomes one
-cell wide but it is *not* moved back to the previous line.
-
-To avoid this issue, it is recommended applications detect when ``U+FE0E`` is
-present and in such cases use the width part of the text sizing protocol
-to control rendering.
