The previous implementation reverted any keyboard-driven window switch
on the next mouse motion event because it compared the hovered window
against the active window rather than against the previously hovered
window. Move the focus-follows-mouse trigger into
set_currently_hovered_window so it fires only when the hover ID
actually transitions, which also covers OS-window-entry.
Add --allow-fallback option to the map command that controls shifted
and ascii (alternate_key) fallback for individual key mappings.
For non-Latin keyboard layouts, when the current layout key is
non-ascii (codepoint > 127 and < 0xE000), the alternate_key from
the base layout is used for matching if the mapping opts in via
--allow-fallback=shifted,ascii.
Default kitty bindings use --allow-fallback=shifted,ascii so they
work out of the box with non-Latin layouts. User custom mappings
default to --allow-fallback=shifted (preserving existing shifted_key
behavior without ascii fallback).
--allow-fallback=none disables all fallback for a mapping.
Python side: parse_options_for_map() in options/utils.py handles flag
parsing, ShortcutMapping uses it in __init__. get_shortcut() filters
candidates by per-mapping allow_fallback.
Go side: ParseMap() handles --allow-fallback, KeyAction stores
AllowFallback, ShortcutTracker.Match passes it to matching.
MatchesParsedShortcut defaults to shifted,ascii for hardcoded shortcuts.
Migrated kittens (themes, command_palette, diff, choose_files) to
use ShortcutTracker with configurable map entries.
Tests added for Python (5 test methods) and Go (ParseMap + key matching).
Default is 'no' to avoid forcing the button on all kitty users. When disabled,
the '+' indicator still appears during window drags as a drop target (existing
behaviour). Set to 'yes' to keep it permanently visible as a clickable button.
Implements drag-to-reorder for window title bars, following up on the
merged window title bar feature (#9450) and the design discussion in #9619.
- Drag a title bar and drop on another title bar to swap positions
- Drop on a window body quadrant (left/right/top/bottom) to insert as
a directional split; Splits layout uses insert_window_next_to(), other
layouts fall back to move_window_to_group()
- Drop on a tab bar tab to move the window into that tab
- Drop on another OS window to move into its active tab
- Drop outside kitty to detach into a new OS window
- Tab bar highlights the hovered tab during a window drag, mirroring
how the destination window title bar is highlighted
- toggle_window_title_bars action temporarily force-shows title bars
for drag-to-reorder when they are normally hidden, auto-hiding after
the drag completes
- window_title_bar_drag_threshold option (default 5px) controls how far
the mouse must move before a drag is initiated; 0 disables dragging
MIME type follows the same convention as tab dragging:
application/net.kovidgoyal.kitty-window-{PID}
Ref: #9619
- Add window_title_bar_min_windows (0=never, 1=always, 2+=threshold)
similar to tab_bar_min_tabs, to control when title bars appear
- Remove 'none' choice from window_title_bar so it purely controls
position (top/bottom); disabling is now via min_windows 0
- Only hide title bar for truly empty template strings, not
whitespace-only, so users can have intentionally blank bars

- Rename all options from pane_title_* to window_title_*
- Use foreground/background instead of fg/bg in color option names
- Change color options to to_color_or_none defaulting to None,
falling back to corresponding tab bar colors
- Add bell_symbol, activity_symbol, progress_percent template vars
using existing bell_on_tab and tab_activity_symbol options
- Add custom script support via window_title_bar.py in config dir
(draw_window_title function exposed as {custom} in templates)
- Update C structs, Python references, and regenerate config files

Add an optional title bar that displays above or below each window pane
when multiple windows are visible in a tab. This is similar to tmux's
pane-border-format or Terminator's pane title bars.
New configuration options:
- pane_title_bar: none/top/bottom (default: none)
- pane_title_template: f-string template (same syntax as tab_title_template)
- active_pane_title_template: override for active pane
- pane_title_bar_active_fg/bg: colors for active pane title
- pane_title_bar_inactive_fg/bg: colors for inactive pane titles
- pane_title_bar_align: left/center/right text alignment
The title bars are rendered using virtual Screen objects registered with
the GPU, following the same model as the tab bar. Title bars are
automatically hidden when only a single window is visible.
