Tabs and Windows
-------------------

|kitty| is capable of running multiple programs organized into tabs and windows.
The top level of organization is the :term:`OS window <os_window>`. Each OS
window consists of one or more :term:`tabs <tab>`. Each tab consists of one or more
:term:`kitty windows <window>`. The kitty windows can be arranged in multiple
different :term:`layouts <layout>`, like windows are organized in a tiling
window manager. The keyboard controls (which are :ref:`all customizable
<conf-kitty-shortcuts>`) for tabs and windows are:

Scrolling
~~~~~~~~~~~~~~

=========================   =======================
Action                      Shortcut
=========================   =======================
Line up                     :sc:`scroll_line_up` (also :kbd:`⌥+⌘+⇞` and :kbd:`⌘+↑` on macOS)
Line down                   :sc:`scroll_line_down` (also :kbd:`⌥+⌘+⇟` and :kbd:`⌘+↓` on macOS)
Page up                     :sc:`scroll_page_up` (also :kbd:`⌘+⇞` on macOS)
Page down                   :sc:`scroll_page_down` (also :kbd:`⌘+⇟` on macOS)
Top                         :sc:`scroll_home` (also :kbd:`⌘+↖` on macOS)
Bottom                      :sc:`scroll_end` (also :kbd:`⌘+↘` on macOS)
Previous shell prompt       :sc:`scroll_to_previous_prompt` (see :ref:`shell_integration`)
Next shell prompt           :sc:`scroll_to_next_prompt` (see :ref:`shell_integration`)
Browse scrollback in less   :sc:`show_scrollback`
Browse last cmd output      :sc:`show_last_command_output` (see :ref:`shell_integration`)
=========================   =======================

The scroll actions only take effect when the terminal is in the main screen.
When the alternate screen is active (for example when using a full screen
program like an editor) the key events are instead passed to program running in the
terminal.

Tabs

========================    =======================


Windows
~~~~~~~~~~~~~~~~~~

========================    =======================
Action                      Shortcut
========================    =======================
New window                  :sc:`new_window` (also :kbd:`⌘+↩` on macOS)
New OS window               :sc:`new_os_window` (also :kbd:`⌘+n` on macOS)
Close window                :sc:`close_window` (also :kbd:`⇧+⌘+d` on macOS)
Next window                 :sc:`next_window`
Previous window             :sc:`previous_window`
Move window forward         :sc:`move_window_forward`
Move window backward        :sc:`move_window_backward`
Move window to top          :sc:`move_window_to_top`
Visually focus window       :sc:`focus_visible_window`
Visually swap window        :sc:`swap_with_window`
Focus specific window       :sc:`first_window`, :sc:`second_window` ... :sc:`tenth_window`
                            (also :kbd:`⌘+1`, :kbd:`⌘+2` ... :kbd:`⌘+9` on macOS)
                            (clockwise from the top-left)
========================    =======================

Additionally, you can define shortcuts in :file:`kitty.conf` to focus
neighboring windows and move windows around (similar to window movement in
:program:`vim`)::

   map ctrl+left neighboring_window left
   map shift+left move_window right
   map ctrl+down neighboring_window down
   map shift+down move_window up
   ...

You can also define a shortcut to switch to the previously active window::

   map ctrl+p nth_window -1

:ac:`nth_window` will focus the nth window for positive numbers (starting from
zero) and the previously active windows for negative numbers.

To switch to the nth OS window, you can define :ac:`nth_os_window`. Only
positive numbers are accepted, starting from one.

.. _detach_window:

You can define shortcuts to detach the current window and move it to another tab
or another OS window::

    # moves the window into a new OS window
    map ctrl+f2 detach_window
    # moves the window into a new tab
    map ctrl+f3 detach_window new-tab
    # moves the window into the previously active tab
    map ctrl+f3 detach_window tab-prev
    # moves the window into the tab at the left of the active tab
    map ctrl+f3 detach_window tab-left
    # asks which tab to move the window into
    map ctrl+f4 detach_window ask

Similarly, you can detach the current tab, with::

    # moves the tab into a new OS window
    map ctrl+f2 detach_tab
    # asks which OS Window to move the tab into
    map ctrl+f4 detach_tab ask

Finally, you can define a shortcut to close all windows in a tab other than the
currently active window::

    map f9 close_other_windows_in_tab
