KITTY.CONF(5) kitty KITTY.CONF(5)
NAME
kitty.conf - kitty.conf Documentation
kitty is highly customizable, everything from keyboard shortcuts, to
rendering frames-per-second. See below for an overview of all cus-
tomization possibilities.
You can open the config file within kitty by pressing ctrl+shift+f2
(⌘+, on macOS). A kitty.conf with commented default configurations and
descriptions will be created if the file does not exist. You can
reload the config file within kitty by pressing ctrl+shift+f5 (⌃+⌘+, on
macOS) or sending kitty the SIGUSR1 signal. You can also display the
current configuration by pressing ctrl+shift+f6 (⌥+⌘+, on macOS).
kitty looks for a config file in the OS config directories (usually
~/.config/kitty/kitty.conf) but you can pass a specific path via the
kitty --config option or use the KITTY_CONFIG_DIRECTORY environment
variable. See kitty --config for full details.
Comments can be added to the config file as lines starting with the #
character. This works only if the # character is the first character in
the line.
You can include secondary config files via the include directive. If
you use a relative path for include, it is resolved with respect to the
location of the current config file. Note that environment variables
are expanded, so ${USER}.conf becomes name.conf if USER=name. Also, you
can use globinclude to include files matching a shell glob pattern and
envinclude to include configuration from environment variables. For ex-
ample:
include other.conf
# Include *.conf files from all subdirs of kitty.d inside the kitty config dir
globinclude kitty.d/**/*.conf
# Include the *contents* of all env vars starting with KITTY_CONF_
envinclude KITTY_CONF_*
NOTE:
Syntax highlighting for kitty.conf in vim is available via
vim-kitty.
kitty has very powerful font management. You can configure individual
font faces and even specify special fonts for particular characters.
font_family, bold_font, italic_font, bold_italic_font
font_family monospace
bold_font auto
italic_font auto
bold_italic_font auto
You can specify different fonts for the bold/italic/bold-italic vari-
ants. To get a full list of supported fonts use the kitty +list-fonts
command. By default they are derived automatically, by the OSes font
system. When bold_font or bold_italic_font is set to auto on macOS, the
priority of bold fonts is semi-bold, bold, heavy. Setting them manually
is useful for font families that have many weight variants like Book,
Medium, Thick, etc. For example:
font_family Operator Mono Book
bold_font Operator Mono Medium
italic_font Operator Mono Book Italic
bold_italic_font Operator Mono Medium Italic
font_size
font_size 11.0
Font size (in pts)
force_ltr
force_ltr no
kitty does not support BIDI (bidirectional text), however, for RTL
scripts, words are automatically displayed in RTL. That is to say, in
an RTL script, the words "HELLO WORLD" display in kitty as "WORLD
HELLO", and if you try to select a substring of an RTL-shaped string,
you will get the character that would be there had the the string been
LTR. For example, assuming the Hebrew word ×××××××, selecting the char-
acter that on the screen appears to be × actually writes into the se-
lection buffer the character ×. kitty's default behavior is useful in
conjunction with a filter to reverse the word order, however, if you
wish to manipulate RTL glyphs, it can be very challenging to work with,
so this option is provided to turn it off. Furthermore, this option can
be used with the command line program GNU FriBidi to get BIDI support,
because it will force kitty to always treat the text as LTR, which
FriBidi expects for terminals.
symbol_map
symbol_map U+E0A0-U+E0A3,U+E0C0-U+E0C7 PowerlineSymbols
Map the specified Unicode codepoints to a particular font. Useful if
you need special rendering for some symbols, such as for Powerline.
Avoids the need for patched fonts. Each Unicode code point is specified
in the form U+<code point in hexadecimal>. You can specify multiple
code points, separated by commas and ranges separated by hyphens. This
option can be specified multiple times. The syntax is:
symbol_map codepoints Font Family Name
narrow_symbols
narrow_symbols U+E0A0-U+E0A3,U+E0C0-U+E0C7 1
Usually, for Private Use Unicode characters and some symbol/dingbat
characters, if the character is followed by one or more spaces, kitty
will use those extra cells to render the character larger, if the char-
acter in the font has a wide aspect ratio. Using this option you can
force kitty to restrict the specified code points to render in the
specified number of cells (defaulting to one cell). This option can be
specified multiple times. The syntax is:
narrow_symbols codepoints [optionally the number of cells]
disable_ligatures
disable_ligatures never
Choose how you want to handle multi-character ligatures. The default is
to always render them. You can tell kitty to not render them when the
cursor is over them by using cursor to make editing easier, or have
kitty never render them at all by using always, if you don't like them.
The ligature strategy can be set per-window either using the kitty re-
mote control facility or by defining shortcuts for it in kitty.conf,
for example:
map alt+1 disable_ligatures_in active always
map alt+2 disable_ligatures_in all never
map alt+3 disable_ligatures_in tab cursor
Note that this refers to programming ligatures, typically implemented
using the calt OpenType feature. For disabling general ligatures, use
the font_features option.
font_features
font_features none
Choose exactly which OpenType features to enable or disable. This is
useful as some fonts might have features worthwhile in a terminal. For
example, Fira Code includes a discretionary feature, zero, which in
that font changes the appearance of the zero (0), to make it more eas-
ily distinguishable from Ø. Fira Code also includes other discretionary
features known as Stylistic Sets which have the tags ss01 through ss20.
For the exact syntax to use for individual features, see the HarfBuzz
documentation.
Note that this code is indexed by PostScript name, and not the font
family. This allows you to define very precise feature settings; e.g.
you can disable a feature in the italic font but not in the regular
font.
On Linux, font features are first read from the FontConfig database and
then this option is applied, so they can be configured in a single,
central place.
To get the PostScript name for a font, use kitty +list-fonts --psnames:
$ kitty +list-fonts --psnames | grep Fira
Fira Code
Fira Code Bold (FiraCode-Bold)
Fira Code Light (FiraCode-Light)
Fira Code Medium (FiraCode-Medium)
Fira Code Regular (FiraCode-Regular)
Fira Code Retina (FiraCode-Retina)
The part in brackets is the PostScript name.
Enable alternate zero and oldstyle numerals:
font_features FiraCode-Retina +zero +onum
Enable only alternate zero in the bold font:
font_features FiraCode-Bold +zero
Disable the normal ligatures, but keep the calt feature which (in this
font) breaks up monotony:
font_features TT2020StyleB-Regular -liga +calt
In conjunction with force_ltr, you may want to disable Arabic shaping
entirely, and only look at their isolated forms if they show up in a
document. You can do this with e.g.:
font_features UnifontMedium +isol -medi -fina -init
modify_font
modify_font
Modify font characteristics such as the position or thickness of the
underline and strikethrough. The modifications can have the suffix px
for pixels or % for percentage of original value. No suffix means use
pts. For example:
modify_font underline_position -2
modify_font underline_thickness 150%
modify_font strikethrough_position 2px
Additionally, you can modify the size of the cell in which each font
glyph is rendered and the baseline at which the glyph is placed in the
cell. For example:
modify_font cell_width 80%
modify_font cell_height -2px
modify_font baseline 3
Note that modifying the baseline will automatically adjust the under-
line and strikethrough positions by the same amount. Increasing the
baseline raises glyphs inside the cell and decreasing it lowers them.
Decreasing the cell size might cause rendering artifacts, so use with
care.
box_drawing_scale
box_drawing_scale 0.001, 1, 1.5, 2
The sizes of the lines used for the box drawing Unicode characters.
These values are in pts. They will be scaled by the monitor DPI to ar-
rive at a pixel value. There must be four values corresponding to
thin, normal, thick, and very thick lines.
cursor
cursor #cccccc
Default cursor color. If set to the special value none the cursor will
be rendered with a "reverse video" effect. It's color will be the color
of the text in the cell it is over and the text will be rendered with
the background color of the cell. Note that if the program running in
the terminal sets a cursor color, this takes precedence. Also, the cur-
sor colors are modified if the cell background and foreground colors
have very low contrast.
cursor_text_color
cursor_text_color #111111
The color of text under the cursor. If you want it rendered with the
background color of the cell underneath instead, use the special key-
word: background. Note that if cursor is set to none then this option
is ignored.
cursor_shape
cursor_shape block
The cursor shape can be one of block, beam, underline. Note that when
reloading the config this will be changed only if the cursor shape has
not been set by the program running in the terminal. This sets the de-
fault cursor shape, applications running in the terminal can override
it. In particular, shell integration in kitty sets the cursor shape to
beam at shell prompts. You can avoid this by setting shell_integration
to no-cursor.
cursor_beam_thickness
cursor_beam_thickness 1.5
The thickness of the beam cursor (in pts).
cursor_underline_thickness
cursor_underline_thickness 2.0
The thickness of the underline cursor (in pts).
cursor_blink_interval
cursor_blink_interval -1
The interval to blink the cursor (in seconds). Set to zero to disable
blinking. Negative values mean use system default. Note that the mini-
mum interval will be limited to repaint_delay.
cursor_stop_blinking_after
cursor_stop_blinking_after 15.0
Stop blinking cursor after the specified number of seconds of keyboard
inactivity. Set to zero to never stop blinking.
scrollback_lines
scrollback_lines 2000
Number of lines of history to keep in memory for scrolling back. Memory
is allocated on demand. Negative numbers are (effectively) infinite
scrollback. Note that using very large scrollback is not recommended
as it can slow down performance of the terminal and also use large
amounts of RAM. Instead, consider using scrollback_pager_history_size.
Note that on config reload if this is changed it will only affect newly
created windows, not existing ones.
scrollback_pager
scrollback_pager less --chop-long-lines --RAW-CONTROL-CHARS +INPUT_LINE_NUMBER
Program with which to view scrollback in a new window. The scrollback
buffer is passed as STDIN to this program. If you change it, make sure
the program you use can handle ANSI escape sequences for colors and
text formatting. INPUT_LINE_NUMBER in the command line above will be
replaced by an integer representing which line should be at the top of
the screen. Similarly CURSOR_LINE and CURSOR_COLUMN will be replaced by
the current cursor position or set to 0 if there is no cursor, for ex-
ample, when showing the last command output.
scrollback_pager_history_size
scrollback_pager_history_size 0
Separate scrollback history size (in MB), used only for browsing the
scrollback buffer with pager. This separate buffer is not available for
interactive scrolling but will be piped to the pager program when view-
ing scrollback buffer in a separate window. The current implementation
stores the data in UTF-8, so approximatively 10000 lines per megabyte
at 100 chars per line, for pure ASCII, unformatted text. A value of
zero or less disables this feature. The maximum allowed size is 4GB.
Note that on config reload if this is changed it will only affect newly
created windows, not existing ones.
scrollback_fill_enlarged_window
scrollback_fill_enlarged_window no
Fill new space with lines from the scrollback buffer after enlarging a
window.
wheel_scroll_multiplier
wheel_scroll_multiplier 5.0
Multiplier for the number of lines scrolled by the mouse wheel. Note
that this is only used for low precision scrolling devices, not for
high precision scrolling devices on platforms such as macOS and Way-
land. Use negative numbers to change scroll direction. See also
wheel_scroll_min_lines.
wheel_scroll_min_lines
wheel_scroll_min_lines 1
The minimum number of lines scrolled by the mouse wheel. The scroll
multiplier only takes effect after it reaches this number. Note that
this is only used for low precision scrolling devices like wheel mice
that scroll by very small amounts when using the wheel. With a negative
number, the minimum number of lines will always be added.
touch_scroll_multiplier
touch_scroll_multiplier 1.0
Multiplier for the number of lines scrolled by a touchpad. Note that
this is only used for high precision scrolling devices on platforms
such as macOS and Wayland. Use negative numbers to change scroll direc-
tion.
mouse_hide_wait
mouse_hide_wait 3.0
Hide mouse cursor after the specified number of seconds of the mouse
not being used. Set to zero to disable mouse cursor hiding. Set to a
negative value to hide the mouse cursor immediately when typing text.
Disabled by default on macOS as getting it to work robustly with the
ever-changing sea of bugs that is Cocoa is too much effort.
url_color, url_style
url_color #0087bd
url_style curly
The color and style for highlighting URLs on mouse-over. url_style can
be one of: none, straight, double, curly, dotted, dashed.
open_url_with
open_url_with default
The program to open clicked URLs. The special value default with first
look for any URL handlers defined via the Scripting the mouse click fa-
cility and if non are found, it will use the Operating System's default
URL handler (open on macOS and xdg-open on Linux).
url_prefixes
url_prefixes file ftp ftps gemini git gopher http https irc ircs kitty mailto news sftp ssh
The set of URL prefixes to look for when detecting a URL under the
mouse cursor.
detect_urls
detect_urls yes
Detect URLs under the mouse. Detected URLs are highlighted with an un-
derline and the mouse cursor becomes a hand over them. Even if this op-
tion is disabled, URLs are still clickable.
url_excluded_characters
url_excluded_characters
Additional characters to be disallowed from URLs, when detecting URLs
under the mouse cursor. By default, all characters that are legal in
URLs are allowed.
copy_on_select
copy_on_select no
Copy to clipboard or a private buffer on select. With this set to clip-
board, selecting text with the mouse will cause the text to be copied
to clipboard. Useful on platforms such as macOS that do not have the
concept of primary selection. You can instead specify a name such as a1
to copy to a private kitty buffer. Map a shortcut with the
paste_from_buffer action to paste from this private buffer. For exam-
ple:
copy_on_select a1
map shift+cmd+v paste_from_buffer a1
Note that copying to the clipboard is a security risk, as all programs,
including websites open in your browser can read the contents of the
system clipboard.
paste_actions
paste_actions quote-urls-at-prompt
A comma separated list of actions to take when pasting text into the
terminal. The supported paste actions are:
quote-urls-at-prompt:
If the text being pasted is a URL and the cursor is at a shell
prompt, automatically quote the URL (needs shell_integration).
confirm:
Confirm the paste if bracketed paste mode is not active or there
is more a large amount of text being pasted.
filter:
Run the filter_paste() function from the file paste-actions.py
in the kitty config directory on the pasted text. The text re-
turned by the function will be actually pasted.
strip_trailing_spaces
strip_trailing_spaces never
Remove spaces at the end of lines when copying to clipboard. A value of
smart will do it when using normal selections, but not rectangle selec-
tions. A value of always will always do it.
select_by_word_characters
select_by_word_characters @-./_~?&=%+#
Characters considered part of a word when double clicking. In addition
to these characters any character that is marked as an alphanumeric
character in the Unicode database will be matched.
select_by_word_characters_forward
select_by_word_characters_forward
Characters considered part of a word when extending the selection for-
ward on double clicking. In addition to these characters any character
that is marked as an alphanumeric character in the Unicode database
will be matched.
If empty (default) select_by_word_characters will be used for both di-
rections.
click_interval
click_interval -1.0
The interval between successive clicks to detect double/triple clicks
(in seconds). Negative numbers will use the system default instead, if
available, or fallback to 0.5.
focus_follows_mouse
focus_follows_mouse no
Set the active window to the window under the mouse when moving the
mouse around.
pointer_shape_when_grabbed
pointer_shape_when_grabbed arrow
The shape of the mouse pointer when the program running in the terminal
grabs the mouse. Valid values are: arrow, beam and hand.
default_pointer_shape
default_pointer_shape beam
The default shape of the mouse pointer. Valid values are: arrow, beam
and hand.
pointer_shape_when_dragging
pointer_shape_when_dragging beam
The default shape of the mouse pointer when dragging across text. Valid
values are: arrow, beam and hand.
MOUSE ACTIONS
Mouse buttons can be mapped to perform arbitrary actions. The syntax
is:
mouse_map button-name event-type modes action
Where button-name is one of left, middle, right, b1 ... b8 with added
keyboard modifiers. For example: ctrl+shift+left refers to holding the
Ctrl+Shift keys while clicking with the left mouse button. The value b1
... b8 can be used to refer to up to eight buttons on a mouse.
event-type is one of press, release, doublepress, triplepress, click,
doubleclick. modes indicates whether the action is performed when the
mouse is grabbed by the program running in the terminal, or not. The
values are grabbed or ungrabbed or a comma separated combination of
them. grabbed refers to when the program running in the terminal has
requested mouse events. Note that the click and double click events
have a delay of click_interval to disambiguate from double and triple
presses.
You can run kitty with the kitty --debug-input command line option to
see mouse events. See the builtin actions below to get a sense of what
is possible.
If you want to unmap an action, map it to no_op. For example, to dis-
able opening of URLs with a plain click:
mouse_map left click ungrabbed no_op
See all the mappable actions including mouse actions here.
NOTE:
Once a selection is started, releasing the button that started it
will automatically end it and no release event will be dispatched.
clear_all_mouse_actions
clear_all_mouse_actions no
Remove all mouse action definitions up to this point. Useful, for in-
stance, to remove the default mouse actions.
Click the link under the mouse or move the cursor
mouse_map left click ungrabbed mouse_handle_click selection link prompt
First check for a selection and if one exists do nothing. Then check
for a link under the mouse cursor and if one exists, click it. Finally
check if the click happened at the current shell prompt and if so, move
the cursor to the click location. Note that this requires shell inte-
gration to work.
Click the link under the mouse or move the cursor even when grabbed
mouse_map shift+left click grabbed,ungrabbed mouse_handle_click selection link prompt
Same as above, except that the action is performed even when the mouse
is grabbed by the program running in the terminal.
Click the link under the mouse cursor
mouse_map ctrl+shift+left release grabbed,ungrabbed mouse_handle_click link
Variant with Ctrl+Shift is present because the simple click based ver-
sion has an unavoidable delay of click_interval, to disambiguate clicks
from double clicks.
Discard press event for link click
mouse_map ctrl+shift+left press grabbed discard_event
Prevent this press event from being sent to the program that has
grabbed the mouse, as the corresponding release event is used to open a
URL.
Paste from the primary selection
mouse_map middle release ungrabbed paste_from_selection
Start selecting text
mouse_map left press ungrabbed mouse_selection normal
Start selecting text in a rectangle
mouse_map ctrl+alt+left press ungrabbed mouse_selection rectangle
Select a word
mouse_map left doublepress ungrabbed mouse_selection word
Select a line
mouse_map left triplepress ungrabbed mouse_selection line
Select line from point
mouse_map ctrl+alt+left triplepress ungrabbed mouse_selection line_from_point
Select from the clicked point to the end of the line.
Extend the current selection
mouse_map right press ungrabbed mouse_selection extend
If you want only the end of the selection to be moved instead of the
nearest boundary, use move-end instead of extend.
Paste from the primary selection even when grabbed
mouse_map shift+middle release ungrabbed,grabbed paste_selection
mouse_map shift+middle press grabbed discard_event
Start selecting text even when grabbed
mouse_map shift+left press ungrabbed,grabbed mouse_selection normal
Start selecting text in a rectangle even when grabbed
mouse_map ctrl+shift+alt+left press ungrabbed,grabbed mouse_selection rectangle
Select a word even when grabbed
mouse_map shift+left doublepress ungrabbed,grabbed mouse_selection word
Select a line even when grabbed
mouse_map shift+left triplepress ungrabbed,grabbed mouse_selection line
Select line from point even when grabbed
mouse_map ctrl+shift+alt+left triplepress ungrabbed,grabbed mouse_selection line_from_point
Select from the clicked point to the end of the line even when grabbed.
Extend the current selection even when grabbed
mouse_map shift+right press ungrabbed,grabbed mouse_selection extend
Show clicked command output in pager
mouse_map ctrl+shift+right press ungrabbed mouse_show_command_output
Requires shell integration to work.
repaint_delay
repaint_delay 10
Delay between screen updates (in milliseconds). Decreasing it, in-
creases frames-per-second (FPS) at the cost of more CPU usage. The de-
fault value yields ~100 FPS which is more than sufficient for most
uses. Note that to actually achieve 100 FPS, you have to either set
sync_to_monitor to no or use a monitor with a high refresh rate. Also,
to minimize latency when there is pending input to be processed, this
option is ignored.
input_delay
input_delay 3
Delay before input from the program running in the terminal is pro-
cessed (in milliseconds). Note that decreasing it will increase respon-
siveness, but also increase CPU usage and might cause flicker in full
screen programs that redraw the entire screen on each loop, because
kitty is so fast that partial screen updates will be drawn.
sync_to_monitor
sync_to_monitor yes
Sync screen updates to the refresh rate of the monitor. This prevents
screen tearing when scrolling. However, it limits the rendering speed
to the refresh rate of your monitor. With a very high speed mouse/high
keyboard repeat rate, you may notice some slight input latency. If so,
set this to no.
enable_audio_bell
enable_audio_bell yes
The audio bell. Useful to disable it in environments that require si-
lence.
visual_bell_duration
visual_bell_duration 0.0
The visual bell duration (in seconds). Flash the screen when a bell oc-
curs for the specified number of seconds. Set to zero to disable.
visual_bell_color
visual_bell_color none
The color used by visual bell. Set to none will fall back to selection
background color. If you feel that the visual bell is too bright, you
can set it to a darker color.
window_alert_on_bell
window_alert_on_bell yes
Request window attention on bell. Makes the dock icon bounce on macOS
or the taskbar flash on linux.
bell_on_tab
bell_on_tab "🔔 "
Some text or a Unicode symbol to show on the tab if a window in the tab
that does not have focus has a bell. If you want to use leading or
trailing spaces, surround the text with quotes. See tab_title_template
for how this is rendered.
For backwards compatibility, values of yes, y and true are converted to
the default bell symbol and no, n, false and none are converted to the
empty string.
command_on_bell
command_on_bell none
Program to run when a bell occurs. The environment variable
KITTY_CHILD_CMDLINE can be used to get the program running in the win-
dow in which the bell occurred.
bell_path
bell_path none
Path to a sound file to play as the bell sound. If set to none, the
system default bell sound is used. Must be in a format supported by the
operating systems sound API, such as WAV or OGA on Linux (libcanberra)
or AIFF, MP3 or WAV on macOS (NSSound)
remember_window_size, initial_window_width, initial_window_height
remember_window_size yes
initial_window_width 640
initial_window_height 400
If enabled, the window size will be remembered so that new instances of
kitty will have the same size as the previous instance. If disabled,
the window will initially have size configured by initial_win-
dow_width/height, in pixels. You can use a suffix of "c" on the
width/height values to have them interpreted as number of cells instead
of pixels.
enabled_layouts
enabled_layouts *
The enabled window layouts. A comma separated list of layout names. The
special value all means all layouts. The first listed layout will be
used as the startup layout. Default configuration is all layouts in al-
phabetical order. For a list of available layouts, see the Layouts.
window_resize_step_cells, window_resize_step_lines
window_resize_step_cells 2
window_resize_step_lines 2
The step size (in units of cell width/cell height) to use when resizing
kitty windows in a layout with the shortcut ctrl+shift+r. The cells
value is used for horizontal resizing, and the lines value is used for
vertical resizing.
window_border_width
window_border_width 0.5pt
The width of window borders. Can be either in pixels (px) or pts (pt).
Values in pts will be rounded to the nearest number of pixels based on
screen resolution. If not specified, the unit is assumed to be pts.
Note that borders are displayed only when more than one window is visi-
ble. They are meant to separate multiple windows.
draw_minimal_borders
draw_minimal_borders yes
Draw only the minimum borders needed. This means that only the borders
that separate the inactive window from a neighbor are drawn. Note that
setting a non-zero window_margin_width overrides this and causes all
borders to be drawn.
window_margin_width
window_margin_width 0
The window margin (in pts) (blank area outside the border). A single
value sets all four sides. Two values set the vertical and horizontal
sides. Three values set top, horizontal and bottom. Four values set
top, right, bottom and left.
single_window_margin_width
single_window_margin_width -1
The window margin to use when only a single window is visible (in pts).
Negative values will cause the value of window_margin_width to be used
instead. A single value sets all four sides. Two values set the verti-
cal and horizontal sides. Three values set top, horizontal and bottom.
Four values set top, right, bottom and left.
window_padding_width
window_padding_width 0
The window padding (in pts) (blank area between the text and the window
border). A single value sets all four sides. Two values set the verti-
cal and horizontal sides. Three values set top, horizontal and bottom.
Four values set top, right, bottom and left.
placement_strategy
placement_strategy center
When the window size is not an exact multiple of the cell size, the
cell area of the terminal window will have some extra padding on the
sides. You can control how that padding is distributed with this op-
tion. Using a value of center means the cell area will be placed cen-
trally. A value of top-left means the padding will be only at the bot-
tom and right edges.
active_border_color
active_border_color #00ff00
The color for the border of the active window. Set this to none to not
draw borders around the active window.
inactive_border_color
inactive_border_color #cccccc
The color for the border of inactive windows.
bell_border_color
bell_border_color #ff5a00
The color for the border of inactive windows in which a bell has oc-
curred.
inactive_text_alpha
inactive_text_alpha 1.0
Fade the text in inactive windows by the specified amount (a number be-
tween zero and one, with zero being fully faded).
hide_window_decorations
hide_window_decorations no
Hide the window decorations (title-bar and window borders) with yes. On
macOS, titlebar-only can be used to only hide the titlebar. Whether
this works and exactly what effect it has depends on the window man-
ager/operating system. Note that the effects of changing this option
when reloading config are undefined.
window_logo_path
window_logo_path none
Path to a logo image. Must be in PNG format. Relative paths are inter-
preted relative to the kitty config directory. The logo is displayed in
a corner of every kitty window. The position is controlled by
window_logo_position. Individual windows can be configured to have
different logos either using the launch action or the remote control
facility.
window_logo_position
window_logo_position bottom-right
Where to position the window logo in the window. The value can be one
of: top-left, top, top-right, left, center, right, bottom-left, bottom,
bottom-right.
window_logo_alpha
window_logo_alpha 0.5
The amount the logo should be faded into the background. With zero be-
ing fully faded and one being fully opaque.
resize_debounce_time
resize_debounce_time 0.1
The time to wait before redrawing the screen when a resize event is re-
ceived (in seconds). On platforms such as macOS, where the operating
system sends events corresponding to the start and end of a resize,
this number is ignored.
resize_draw_strategy
resize_draw_strategy static
Choose how kitty draws a window while a resize is in progress. A value
of static means draw the current window contents, mostly unchanged. A
value of scale means draw the current window contents scaled. A value
of blank means draw a blank window. A value of size means show the win-
dow size in cells.
resize_in_steps
resize_in_steps no
Resize the OS window in steps as large as the cells, instead of with
the usual pixel accuracy. Combined with initial_window_width and
initial_window_height in number of cells, this option can be used to
keep the margins as small as possible when resizing the OS window. Note
that this does not currently work on Wayland.
visual_window_select_characters
visual_window_select_characters 1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ
The list of characters for visual window selection. For example, for
selecting a window to focus on with ctrl+shift+f7. The value should be
a series of unique numbers or alphabets, case insensitive, from the set
[0-9A-Z]. Specify your preference as a string of characters.
confirm_os_window_close
confirm_os_window_close -1
Ask for confirmation when closing an OS window or a tab with at least
this number of kitty windows in it by window manager (e.g. clicking the
window close button or pressing the operating system shortcut to close
windows) or by the close_tab action. A value of zero disables confirma-
tion. This confirmation also applies to requests to quit the entire ap-
plication (all OS windows, via the quit action). Negative values are
converted to positive ones, however, with shell_integration enabled,
using negative values means windows sitting at a shell prompt are not
counted, only windows where some command is currently running. Note
that if you want confirmation when closing individual windows, you can
map the close_window_with_confirmation action.
tab_bar_edge
tab_bar_edge bottom
The edge to show the tab bar on, top or bottom.
tab_bar_margin_width
tab_bar_margin_width 0.0
The margin to the left and right of the tab bar (in pts).
tab_bar_margin_height
tab_bar_margin_height 0.0 0.0
The margin above and below the tab bar (in pts). The first number is
the margin between the edge of the OS Window and the tab bar. The sec-
ond number is the margin between the tab bar and the contents of the
current tab.
tab_bar_style
tab_bar_style fade
The tab bar style, can be one of:
fade Each tab's edges fade into the background color. (See also
tab_fade)
slant Tabs look like the tabs in a physical file.
separator
Tabs are separated by a configurable separator. (See also
tab_separator)
powerline
Tabs are shown as a continuous line with "fancy" separators.
(See also tab_powerline_style)
custom A user-supplied Python function called draw_tab is loaded from
the file tab_bar.py in the kitty config directory. For examples
of how to write such a function, see the functions named
draw_tab_with_* in kitty's source code: kitty/tab_bar.py. See
also this discussion for examples from kitty users.
hidden The tab bar is hidden. If you use this, you might want to create
a mapping for the select_tab action which presents you with a
list of tabs and allows for easy switching to a tab.
tab_bar_align
tab_bar_align left
The horizontal alignment of the tab bar, can be one of: left, center,
right.
tab_bar_min_tabs
tab_bar_min_tabs 2
The minimum number of tabs that must exist before the tab bar is shown.
tab_switch_strategy
tab_switch_strategy previous
The algorithm to use when switching to a tab when the current tab is
closed. The default of previous will switch to the last used tab. A
value of left will switch to the tab to the left of the closed tab. A
value of right will switch to the tab to the right of the closed tab. A
value of last will switch to the right-most tab.
tab_fade
tab_fade 0.25 0.5 0.75 1
Control how each tab fades into the background when using fade for the
tab_bar_style. Each number is an alpha (between zero and one) that con-
trols how much the corresponding cell fades into the background, with
zero being no fade and one being full fade. You can change the number
of cells used by adding/removing entries to this list.
tab_separator
tab_separator " ┇"
The separator between tabs in the tab bar when using separator as the
tab_bar_style.
tab_powerline_style
tab_powerline_style angled
The powerline separator style between tabs in the tab bar when using
powerline as the tab_bar_style, can be one of: angled, slanted, round.
tab_activity_symbol
tab_activity_symbol none
Some text or a Unicode symbol to show on the tab if a window in the tab
that does not have focus has some activity. If you want to use leading
or trailing spaces, surround the text with quotes. See
tab_title_template for how this is rendered.
tab_title_template
tab_title_template "{fmt.fg.red}{bell_symbol}{activity_symbol}{fmt.fg.tab}{title}"
A template to render the tab title. The default just renders the title
with optional symbols for bell and activity. If you wish to include the
tab-index as well, use something like: {index}:{title}. Useful if you
have shortcuts mapped for goto_tab N. If you prefer to see the index as
a superscript, use {sup.index}. All data available is:
title The current tab title.
index The tab index useable with goto_tab N shortcuts.
layout_name
The current layout name.
num_windows
The number of windows in the tab.
num_window_groups
The number of window groups (not counting overlay windows) in
the tab.
tab.active_wd
The working directory of the currently active window in the tab
(expensive, requires syscall).
max_title_length
The maximum title length available.
Note that formatting is done by Python's string formatting machinery,
so you can use, for instance, {layout_name[:2].upper()} to show only
the first two letters of the layout name, upper-cased. If you want to
style the text, you can use styling directives, for example:
{fmt.fg.red}red{fmt.fg.tab}normal{fmt.bg._00FF00}greenbg{fmt.bg.tab}.
Similarly, for bold and italic: {fmt.bold}bold{fmt.nobold}nor-
mal{fmt.italic}italic{fmt.noitalic}. Note that for backward compati-
bility, if {bell_symbol} or {activity_symbol} are not present in the
template, they are prepended to it.
active_tab_title_template
active_tab_title_template none
Template to use for active tabs. If not specified falls back to
tab_title_template.
active_tab_foreground, active_tab_background, active_tab_font_style,
inactive_tab_foreground, inactive_tab_background, inac-
tive_tab_font_style
active_tab_foreground #000
active_tab_background #eee
active_tab_font_style bold-italic
inactive_tab_foreground #444
inactive_tab_background #999
inactive_tab_font_style normal
Tab bar colors and styles.
tab_bar_background
tab_bar_background none
Background color for the tab bar. Defaults to using the terminal back-
ground color.
tab_bar_margin_color
tab_bar_margin_color none
Color for the tab bar margin area. Defaults to using the terminal back-
ground color.
foreground, background
foreground #dddddd
background #000000
The foreground and background colors.
background_opacity
background_opacity 1.0
The opacity of the background. A number between zero and one, where one
is opaque and zero is fully transparent. This will only work if sup-
ported by the OS (for instance, when using a compositor under X11).
Note that it only sets the background color's opacity in cells that
have the same background color as the default terminal background, so
that things like the status bar in vim, powerline prompts, etc. still
look good. But it means that if you use a color theme with a background
color in your editor, it will not be rendered as transparent. Instead
you should change the default background color in your kitty config and
not use a background color in the editor color scheme. Or use the es-
cape codes to set the terminals default colors in a shell script to
launch your editor. Be aware that using a value less than 1.0 is a
(possibly significant) performance hit. If you want to dynamically
change transparency of windows, set dynamic_background_opacity to yes
(this is off by default as it has a performance cost). Changing this
option when reloading the config will only work if
dynamic_background_opacity was enabled in the original config.
background_image
background_image none
Path to a background image. Must be in PNG format.
background_image_layout
background_image_layout tiled
Whether to tile, scale or clamp the background image. The value can be
one of tiled, mirror-tiled, scaled, clamped or centered.
background_image_linear
background_image_linear no
When background image is scaled, whether linear interpolation should be
used.
dynamic_background_opacity
dynamic_background_opacity no
Allow changing of the background_opacity dynamically, using either key-
board shortcuts (ctrl+shift+a>m and ctrl+shift+a>l) or the remote con-
trol facility. Changing this option by reloading the config is not sup-
ported.
background_tint
background_tint 0.0
How much to tint the background image by the background color. This
option makes it easier to read the text. Tinting is done using the cur-
rent background color for each window. This option applies only if
background_opacity is set and transparent windows are supported or
background_image is set.
dim_opacity
dim_opacity 0.75
How much to dim text that has the DIM/FAINT attribute set. One means no
dimming and zero means fully dimmed (i.e. invisible).
selection_foreground, selection_background
selection_foreground #000000
selection_background #fffacd
The foreground and background colors for text selected with the mouse.
Setting both of these to none will cause a "reverse video" effect for
selections, where the selection will be the cell text color and the
text will become the cell background color. Setting only selec-
tion_foreground to none will cause the foreground color to be used un-
changed. Note that these colors can be overridden by the program run-
ning in the terminal.
THE COLOR TABLE
The 256 terminal colors. There are 8 basic colors, each color has a
dull and bright version, for the first 16 colors. You can set the re-
maining 240 colors as color16 to color255.
color0, color8
color0 #000000
color8 #767676
black
color1, color9
color1 #cc0403
color9 #f2201f
red
color2, color10
color2 #19cb00
color10 #23fd00
green
color3, color11
color3 #cecb00
color11 #fffd00
yellow
color4, color12
color4 #0d73cc
color12 #1a8fff
blue
color5, color13
color5 #cb1ed1

color7, color15
color7 #dddddd
color15 #ffffff
white
mark1_foreground
mark1_foreground black
Color for marks of type 1
mark1_background
mark1_background #98d3cb
Color for marks of type 1 (light steel blue)
mark2_foreground
mark2_foreground black
Color for marks of type 2
mark2_background
mark2_background #f2dcd3
Color for marks of type 1 (beige)
mark3_foreground
mark3_foreground black
Color for marks of type 3
mark3_background
mark3_background #f274bc
Color for marks of type 3 (violet)
shell
shell .
The shell program to execute. The default value of . means to use what-
ever shell is set as the default shell for the current user. Note that
on macOS if you change this, you might need to add --login and --inter-
active to ensure that the shell starts in interactive mode and reads
its startup rc files.
editor
editor .
The terminal based text editor (such as vim or nano) to use when edit-
ing the kitty config file or similar tasks.
The default value of . means to use the environment variables VISUAL
and EDITOR in that order. If these variables aren't set, kitty will run
your shell ($SHELL -l -i -c env) to see if your shell startup rc files
set VISUAL or EDITOR. If that doesn't work, kitty will cycle through
various known editors (vim, emacs, etc.) and take the first one that
exists on your system.
close_on_child_death
close_on_child_death no
Close the window when the child process (shell) exits. With the default
value no, the terminal will remain open when the child exits as long as
there are still processes outputting to the terminal (for example dis-
owned or backgrounded processes). When enabled with yes, the window
will close as soon as the child process exits. Note that setting it to
yes means that any background processes still using the terminal can
fail silently because their stdout/stderr/stdin no longer work.
remote_control_password
remote_control_password
Allow other programs to control kitty using passwords. This option can
be specified multiple times to add multiple passwords. If no passwords
are present kitty will ask the user for permission if a program tries
to use remote control with a password. A password can also optionally
be associated with a set of allowed remote control actions. For exam-
ple:
remote_control_password "my passphrase" get-colors set-colors focus-window focus-tab
Only the specified actions will be allowed when using this password.
Glob patterns can be used too, for example:
remote_control_password "my passphrase" set-tab-* resize-*
To get a list of available actions, run:
kitty @ --help
A set of actions to be allowed when no password is sent can be speci-
fied by using an empty password, for example:
remote_control_password "" *-colors
Finally, the path to a python module can be specified that provides a
function is_cmd_allowed that is used to check every remote control com-
mand. See Customizing authorization with your own program for details.
For example:
remote_control_password "my passphrase" my_rc_command_checker.py
Relative paths are resolved from the kitty configuration directory.
allow_remote_control
allow_remote_control no
Allow other programs to control kitty. If you turn this on, other pro-
grams can control all aspects of kitty, including sending text to kitty
windows, opening new windows, closing windows, reading the content of
windows, etc. Note that this even works over SSH connections. The de-
fault setting of no prevents any form of remote control. The meaning of
the various values are:
password
Remote control requests received over both the TTY device and
the socket are confirmed based on passwords, see
remote_control_password.
socket-only
Remote control requests received over a socket are accepted un-
conditionally. Requests received over the TTY are denied. See
listen_on.
socket Remote control requests received over a socket are accepted un-
conditionally. Requests received over the TTY are confirmed
based on password.
no Remote control is completely disabled.
yes Remote control requests are always accepted.
listen_on
listen_on none
Listen to the specified UNIX socket for remote control connections.
Note that this will apply to all kitty instances. It can be overridden
by the kitty --listen-on command line option, which also supports lis-
tening on a TCP socket. This option accepts only UNIX sockets, such as
unix:${TEMP}/mykitty or unix:@mykitty (on Linux). Environment variables
are expanded and relative paths are resolved with respect to the tempo-
rary directory. If {kitty_pid} is present, then it is replaced by the
PID of the kitty process, otherwise the PID of the kitty process is ap-
pended to the value, with a hyphen. See the help for kitty --listen-on
for more details. Note that this will be ignored unless
allow_remote_control is set to either: yes, socket or socket-only.
Changing this option by reloading the config is not supported.
env
env
Specify the environment variables to be set in all child processes. Us-
ing the name with an equal sign (e.g. env VAR=) will set it to the
empty string. Specifying only the name (e.g. env VAR) will remove the
variable from the child process' environment. Note that environment
variables are expanded recursively, for example:
env VAR1=a
env VAR2=${HOME}/${VAR1}/b
The value of VAR2 will be <path to home directory>/a/b.
watcher
watcher
Path to python file which will be loaded for Watching launched windows.
Can be specified more than once to load multiple watchers. The watchers
will be added to every kitty window. Relative paths are resolved rela-
tive to the kitty config directory. Note that reloading the config will
only affect windows created after the reload.
exe_search_path
exe_search_path
Control where kitty finds the programs to run. The default search order
is: First search the system wide PATH, then ~/.local/bin and ~/bin. If
still not found, the PATH defined in the login shell after sourcing all
its startup files is tried. Finally, if present, the PATH specified by
the env option is tried.
This option allows you to prepend, append, or remove paths from this
search order. It can be specified multiple times for multiple paths. A
simple path will be prepended to the search order. A path that starts
with the + sign will be append to the search order, after ~/bin above.
A path that starts with the - sign will be removed from the entire
search order. For example:
exe_search_path /some/prepended/path
exe_search_path +/some/appended/path
exe_search_path -/some/excluded/path
update_check_interval
update_check_interval 24
The interval to periodically check if an update to kitty is available
(in hours). If an update is found, a system notification is displayed
informing you of the available update. The default is to check every 24
hours, set to zero to disable. Update checking is only done by the of-
ficial binary builds. Distro packages or source builds do not do update
checking. Changing this option by reloading the config is not sup-
ported.
startup_session
startup_session none
Path to a session file to use for all kitty instances. Can be overrid-
den by using the kitty --session command line option for individual in-
stances. See Startup Sessions in the kitty documentation for details.
Note that relative paths are interpreted with respect to the kitty con-
fig directory. Environment variables in the path are expanded. Chang-
ing this option by reloading the config is not supported.
clipboard_control
clipboard_control write-clipboard write-primary read-clipboard-ask read-primary-ask
Allow programs running in kitty to read and write from the clipboard.
You can control exactly which actions are allowed. The possible actions
are: write-clipboard, read-clipboard, write-primary, read-primary,
read-clipboard-ask, read-primary-ask. The default is to allow writing
to the clipboard and primary selection and to ask for permission when a
program tries to read from the clipboard. Note that disabling the read
confirmation is a security risk as it means that any program, even the
ones running on a remote server via SSH can read your clipboard. See
also clipboard_max_size.
clipboard_max_size
clipboard_max_size 64
The maximum size (in MB) of data from programs running in kitty that
will be stored for writing to the system clipboard. A value of zero
means no size limit is applied. See also clipboard_control.
file_transfer_confirmation_bypass
file_transfer_confirmation_bypass
The password that can be supplied to the file transfer kitten to skip
the transfer confirmation prompt. This should only be used when initi-
ating transfers from trusted computers, over trusted networks or en-
crypted transports, as it allows any programs running on the remote ma-
chine to read/write to the local filesystem, without permission.
allow_hyperlinks
allow_hyperlinks yes
Process hyperlink escape sequences (OSC 8). If disabled OSC 8 escape
sequences are ignored. Otherwise they become clickable links, that you
can click with the mouse or by using the hints kitten. The special
value of ask means that kitty will ask before opening the link when
clicked.
shell_integration
shell_integration enabled
Enable shell integration on supported shells. This enables features
such as jumping to previous prompts, browsing the output of the previ-
ous command in a pager, etc. on supported shells. Set to disabled to
turn off shell integration, completely. It is also possible to disable
individual features, set to a space separated list of these values:
no-rc, no-cursor, no-title, no-cwd, no-prompt-mark, no-complete. See
Shell integration for details.
allow_cloning
allow_cloning ask
Control whether programs running in the terminal can request new win-
dows to be created. The canonical example is clone-in-kitty. By de-
fault, kitty will ask for permission for each clone request. Allowing
cloning unconditionally gives programs running in the terminal (includ-
ing over SSH) permission to execute arbitrary code, as the user who is
running the terminal, on the computer that the terminal is running on.
clone_source_strategies
clone_source_strategies venv,conda,env_var,path
Control what shell code is sourced when running clone-in-kitty in the
newly cloned window. The supported strategies are:
venv Source the file $VIRTUAL_ENV/bin/activate. This is used by the
Python stdlib venv module and allows cloning venvs automati-
cally.
conda Run conda activate $CONDA_DEFAULT_ENV. This supports the virtual
environments created by conda.
env_var
Execute the contents of the environment variable
KITTY_CLONE_SOURCE_CODE with eval.
path Source the file pointed to by the environment variable
KITTY_CLONE_SOURCE_PATH.
This option must be a comma separated list of the above values. This
only source the first valid one in the above order.
term
term xterm-kitty
The value of the TERM environment variable to set. Changing this can
break many terminal programs, only change it if you know what you are
doing, not because you read some advice on "Stack Overflow" to change
it. The TERM variable is used by various programs to get information
about the capabilities and behavior of the terminal. If you change it,
depending on what programs you run, and how different the terminal you
are changing it to is, various things from key-presses, to colors, to
various advanced features may not work. Changing this option by reload-
ing the config will only affect newly created windows.
wayland_titlebar_color
wayland_titlebar_color system
The color of the kitty window's titlebar on Wayland systems with client
side window decorations such as GNOME. A value of system means to use
the default system color, a value of background means to use the back-
ground color of the currently active window and finally you can use an
arbitrary color, such as #12af59 or red.
macos_titlebar_color
macos_titlebar_color system
The color of the kitty window's titlebar on macOS. A value of system
means to use the default system color, light or dark can also be used
to set it explicitly. A value of background means to use the background
color of the currently active window and finally you can use an arbi-
trary color, such as #12af59 or red. WARNING: This option works by us-
ing a hack when arbitrary color (or background) is configured, as there
is no proper Cocoa API for it. It sets the background color of the en-
tire window and makes the titlebar transparent. As such it is incompat-
ible with background_opacity. If you want to use both, you are probably
better off just hiding the titlebar with hide_window_decorations.
macos_option_as_alt
macos_option_as_alt no
Use the Option key as an Alt key on macOS. With this set to no, kitty
will use the macOS native Option+Key to enter Unicode character behav-
ior. This will break any Alt+Key keyboard shortcuts in your terminal
programs, but you can use the macOS Unicode input technique. You can
use the values: left, right or both to use only the left, right or both
Option keys as Alt, instead. Note that kitty itself always treats Op-
tion the same as Alt. This means you cannot use this option to config-
ure different kitty shortcuts for Option+Key vs. Alt+Key. Also, any
kitty shortcuts using Option/Alt+Key will take priority, so that any
such key presses will not be passed to terminal programs running inside
kitty. Changing this option by reloading the config is not supported.
macos_hide_from_tasks
macos_hide_from_tasks no
Hide the kitty window from running tasks on macOS (⌘+Tab and the Dock).
Changing this option by reloading the config is not supported.
macos_quit_when_last_window_closed
macos_quit_when_last_window_closed no
Have kitty quit when all the top-level windows are closed on macOS. By
default, kitty will stay running, even with no open windows, as is the
expected behavior on macOS.
macos_window_resizable
macos_window_resizable yes
Disable this if you want kitty top-level OS windows to not be resizable
on macOS. Changing this option by reloading the config will only affect
newly created OS windows.
macos_thicken_font
macos_thicken_font 0
Draw an extra border around the font with the given width, to increase
legibility at small font sizes on macOS. For example, a value of 0.75
will result in rendering that looks similar to sub-pixel antialiasing
at common font sizes.
macos_traditional_fullscreen
macos_traditional_fullscreen no
Use the macOS traditional full-screen transition, that is faster, but
less pretty.
macos_show_window_title_in
macos_show_window_title_in all
Control where the window title is displayed on macOS. A value of window
will show the title of the currently active window at the top of the
macOS window. A value of menubar will show the title of the currently
active window in the macOS global menu bar, making use of otherwise
wasted space. A value of all will show the title in both places, and
none hides the title. See macos_menubar_title_max_length for how to
control the length of the title in the menu bar.
macos_menubar_title_max_length
macos_menubar_title_max_length 0
The maximum number of characters from the window title to show in the
macOS global menu bar. Values less than one means that there is no max-
imum limit.
macos_custom_beam_cursor
macos_custom_beam_cursor no
Use a custom mouse cursor for macOS that is easier to see on both light
and dark backgrounds. Nowadays, the default macOS cursor already comes
with a white border. WARNING: this might make your mouse cursor invisi-
ble on dual GPU machines. Changing this option by reloading the config
is not supported.
macos_colorspace
macos_colorspace srgb
The colorspace in which to interpret terminal colors. The default of
srgb will cause colors to match those seen in web browsers. The value
of default will use whatever the native colorspace of the display is.
The value of displayp3 will use Apple's special snowflake display P3
color space, which will result in over saturated (brighter) colors with
some color shift. Reloading configuration will change this value only
for newly created OS windows.
linux_display_server
linux_display_server auto
Choose between Wayland and X11 backends. By default, an appropriate
backend based on the system state is chosen automatically. Set it to
x11 or wayland to force the choice. Changing this option by reloading
the config is not supported.
Keys are identified simply by their lowercase Unicode characters. For
example: a for the A key, [ for the left square bracket key, etc. For
functional keys, such as Enter or Escape, the names are present at
Functional key definitions. For modifier keys, the names are ctrl (con-
trol, ⌃), shift (⇧), alt (opt, option, ⌥), super (cmd, command, ⌘).
See also: GLFW mods
On Linux you can also use XKB key names to bind keys that are not sup-
ported by GLFW. See XKB keys for a list of key names. The name to use
is the part after the XKB_KEY_ prefix. Note that you can only use an
XKB key name for keys that are not known as GLFW keys.
Finally, you can use raw system key codes to map keys, again only for
keys that are not known as GLFW keys. To see the system key code for a
key, start kitty with the kitty --debug-input option, kitty will output
some debug text for every key event. In that text look for native_code,
the value of that becomes the key name in the shortcut. For example:
on_key_input: glfw key: 0x61 native_code: 0x61 action: PRESS mods: none text: 'a'
Here, the key name for the A key is 0x61 and you can use it with:
map ctrl+0x61 something
to map Ctrl+A to something.
You can use the special action no_op to unmap a keyboard shortcut that
is assigned in the default configuration:
map kitty_mod+space no_op
If you would like kitty to completely ignore a key event, not even
sending it to the program running in the terminal, map it to
discard_event:
map kitty_mod+f1 discard_event
You can combine multiple actions to be triggered by a single shortcut
with combine action, using the syntax below:
map key combine <separator> action1 <separator> action2 <separator> action3 ...
For example:
map kitty_mod+e combine : new_window : next_layout
This will create a new window and switch to the next available layout.
You can use multi-key shortcuts with the syntax shown below:
map key1>key2>key3 action
For example:
map ctrl+f>2 set_font_size 20
The full list of actions that can be mapped to key presses is available
here.
kitty_mod
kitty_mod ctrl+shift
Special modifier key alias for default shortcuts. You can change the
value of this option to alter all default shortcuts that use kitty_mod.
clear_all_shortcuts
clear_all_shortcuts no
Remove all shortcut definitions up to this point. Useful, for instance,
to remove the default shortcuts.
action_alias
action_alias launch_tab launch --type=tab --cwd=current
Define action aliases to avoid repeating the same options in multiple
mappings. Aliases can be defined for any action and will be expanded
recursively. For example, the above alias allows you to create mappings
to launch a new tab in the current working directory without duplica-
tion:
map f1 launch_tab vim
map f2 launch_tab emacs
Similarly, to alias kitten invocation:
action_alias hints kitten hints --hints-offset=0
kitten_alias
kitten_alias hints hints --hints-offset=0
Like action_alias above, but specifically for kittens. Generally, pre-
fer to use action_alias. This option is a legacy version, present for
backwards compatibility. It causes all invocations of the aliased kit-
ten to be substituted. So the example above will cause all invocations
of the hints kitten to have the --hints-offset=0 option applied.
CLIPBOARD
Copy to clipboard
map ctrl+shift+c copy_to_clipboard
map cmd+c copy_to_clipboard 🍎
There is also a copy_or_interrupt action that can be optionally mapped
to Ctrl+C. It will copy only if there is a selection and send an inter-
rupt otherwise. Similarly, copy_and_clear_or_interrupt will copy and
clear the selection or send an interrupt if there is no selection.
Paste from clipboard
map ctrl+shift+v paste_from_clipboard
map cmd+v paste_from_clipboard 🍎
Paste from selection
map ctrl+shift+s paste_from_selection
map shift+insert paste_from_selection
Pass selection to program
map ctrl+shift+o pass_selection_to_program
You can also pass the contents of the current selection to any program
with pass_selection_to_program. By default, the system's open program
is used, but you can specify your own, the selection will be passed as
a command line argument to the program. For example:
map kitty_mod+o pass_selection_to_program firefox
You can pass the current selection to a terminal program running in a
new kitty window, by using the @selection placeholder:
map kitty_mod+y new_window less @selection

to or the last clicked position. Requires shell integration to work.
Scroll to next shell prompt
map ctrl+shift+x scroll_to_prompt 1
Browse scrollback buffer in pager
map ctrl+shift+h show_scrollback
You can pipe the contents of the current screen and history buffer as
STDIN to an arbitrary program using launch --stdin-source. For exam-
ple, the following opens the scrollback buffer in less in an overlay
window:
map f1 launch --stdin-source=@screen_scrollback --stdin-add-formatting --type=overlay less +G -R
For more details on piping screen and buffer contents to external pro-
grams, see The launch command.
Browse output of the last shell command in pager
map ctrl+shift+g show_last_command_output
You can also define additional shortcuts to get the command output.
For example, to get the first command output on screen:
map f1 show_first_command_output_on_screen
To get the command output that was last accessed by a keyboard action
or mouse action:
map f1 show_last_visited_command_output
You can pipe the output of the last command run in the shell using the
launch action. For example, the following opens the output in less in
an overlay window:
map f1 launch --stdin-source=@last_cmd_output --stdin-add-formatting --type=overlay less +G -R
To get the output of the first command on the screen, use
@first_cmd_output_on_screen. To get the output of the last jumped to
command, use @last_visited_cmd_output.
Requires shell integration to work.
WINDOW MANAGEMENT
New window
map ctrl+shift+enter new_window
map cmd+enter new_window 🍎
You can open a new kitty window running an arbitrary program, for exam-
ple:
map kitty_mod+y launch mutt
You can open a new window with the current working directory set to the
working directory of the current window using:
map ctrl+alt+enter launch --cwd=current
You can open a new window that is allowed to control kitty via the
kitty remote control facility with launch --allow-remote-control. Any
programs running in that window will be allowed to control kitty. For
example:
map ctrl+enter launch --allow-remote-control some_program
You can open a new window next to the currently active window or as the
first window, with:
map ctrl+n launch --location=neighbor
map ctrl+f launch --location=first
For more details, see The launch command.
New OS window
map ctrl+shift+n new_os_window

Just as with new_window above, you can also pass the name of arbitrary
commands to run when using new_tab and new_tab_with_cwd. Finally, if
you want the new tab to open next to the current tab rather than at the
end of the tabs list, use:
map ctrl+t new_tab !neighbor [optional cmd to run]
LAYOUT MANAGEMENT

Decrease background opacity
map ctrl+shift+a>l set_background_opacity -0.1
Make background fully opaque
map ctrl+shift+a>1 set_background_opacity 1
Reset background opacity
map ctrl+shift+a>d set_background_opacity default
Reset the terminal
map ctrl+shift+delete clear_terminal reset active
map opt+cmd+r clear_terminal reset active 🍎
You can create shortcuts to clear/reset the terminal. For example:
# Reset the terminal
map f1 clear_terminal reset active
# Clear the terminal screen by erasing all contents
map f1 clear_terminal clear active
# Clear the terminal scrollback by erasing it
map f1 clear_terminal scrollback active
# Scroll the contents of the screen into the scrollback
map f1 clear_terminal scroll active
# Clear everything up to the line with the cursor
map f1 clear_terminal to_cursor active
If you want to operate on all kitty windows instead of just the current
one, use all instead of active.
It is also possible to remap Ctrl+L to both scroll the current screen
contents into the scrollback buffer and clear the screen, instead of
just clearing the screen, for example, for ZSH add the following to
~/.zshrc:
scroll-and-clear-screen() {
printf '\n%.0s' {1..$LINES}
zle clear-screen
}
zle -N scroll-and-clear-screen
bindkey '^l' scroll-and-clear-screen
Clear up to cursor line
map cmd+k clear_terminal to_cursor active 🍎
Reload kitty.conf
map ctrl+shift+f5 load_config_file
map ctrl+cmd+, load_config_file 🍎
Reload kitty.conf, applying any changes since the last time it was
loaded. Note that a handful of options cannot be dynamically changed
and require a full restart of kitty. Particularly, when changing short-
cuts for actions located on the macOS global menu bar, a full restart
is needed. You can also map a keybinding to load a different config
file, for example:
map f5 load_config /path/to/alternative/kitty.conf
Note that all options from the original kitty.conf are discarded, in
other words the new configuration replace the old ones.
Debug kitty configuration
map ctrl+shift+f6 debug_config
map opt+cmd+, debug_config 🍎
Show details about exactly what configuration kitty is running with and
its host environment. Useful for debugging issues.
Send arbitrary text on key presses
You can tell kitty to send arbitrary (UTF-8) encoded text to the client
program when pressing specified shortcut keys. For example:
map ctrl+alt+a send_text all Special text
This will send "Special text" when you press the Ctrl+Alt+A key combi-
nation. The text to be sent is a python string literal so you can use
escapes like x1b to send control codes or u21fb to send Unicode charac-
ters (or you can just input the Unicode characters directly as UTF-8
text). You can use kitty +kitten show_key to get the key escape codes
you want to emulate.
The first argument to send_text is the keyboard modes in which to acti-
vate the shortcut. The possible values are normal, application, kitty
or a comma separated combination of them. The modes normal and appli-
cation refer to the DECCKM cursor key mode for terminals, and kitty
refers to the kitty extended keyboard protocol. The special value all
means all of them.
Some more examples:
# Output a word and move the cursor to the start of the line (like typing and pressing Home)
map ctrl+alt+a send_text normal Word\x1b[H
map ctrl+alt+a send_text application Word\x1bOH
# Run a command at a shell prompt (like typing the command and pressing Enter)
map ctrl+alt+a send_text normal,application some command with arguments\r
Open kitty Website
map shift+cmd+/ open_url https://sw.kovidgoyal.net/kitty/ 🍎
You can edit a fully commented sample kitty.conf by pressing the
ctrl+shift+f2 shortcut in kitty. This will generate a config file with
full documentation and all settings commented out. If you have a
pre-existing kitty.conf, then that will be used instead, delete it to
see the sample file.
See the list of all the things you can make kitty can do.
