kitty [options] [ program-to-run …]
Run the kitty terminal emulator.
For example: kitty sh -c "echo hello, world. Press ENTER to quit; read"

The top level of organization is the Tab.
Each tab consists of one or more windows.
The windows can be arranged in multiple different layouts, like windows are organized in a tiling window manager.
The keyboard controls for tabs and windows are:

list-fonts
. By default they are derived , by the OSes font system.
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)
adjust_line_height, adjust_column_width
adjust_line_height 0
adjust_column_width 0
Change the size of each character cell . use either numbers as
pixels or percentages (number followed by %), as percentages of the unmodified values.
Negative pixels or percentages less than 100% to reduce sizes (this might cause rendering artifacts).
adjust_baseline
adjust_baseline 0
Adjust the vertical alignment of text (the height in the cell at which text is positioned). Use either numbers,
for as pixels or a percentages (number followed by %),
as the percentage of the line height. A positive value moves the baseline up, and a negative value moves them
down. The underline and strikethrough positions are adjusted accordingly.
symbol_map
symbol_map codepoints Font Family Name
Map the specified unicode codepoints to a particular font. For 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+. specify multiple code points, separated by commas and ranges separated by hyphens.
symbol_map itself can be specified multiple times.
symbol_map U+E0A0-U+E0A3,U+E0C0-U+E0C7 PowerlineSymbols
disable_ligatures
disable_ligatures never
The default is to always render handle multi-character ligatures. .
Not render them when the cursor is over them by using cursor to make editing easier, or have
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 remote 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
This refers to programming ligatures, typically implemented using the calt OpenType feature. For
disabling general ligatures, use the font_features setting.
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 Retina includes a discretionary feature, zero, which in that
font changes the appearance of the zero (0), to make it more easily distinguishable from O. Fira Code Retina
also includes other discretionary features known as Stylistic Sets which have the tags ss01 through ss20.
see the Harfbuzz documentation.
this code is indexed by PostScript name, and not font family. This allows you to define very
precise feature settings; e.g. disable a feature in the italic font but not in the regular font.
On Linux, these are read from the FontConfig database first and then this, setting 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:
font_features FiraCode-Retina +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 iso-
lated forms if they show up in a document. You can do this with e.g.:
font_features UnifontMedium +isol -medi -fina -init
box_drawing_scale
box_drawing_scale 0.001, 1, 1.5, 2
Change 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 arrive at a pixel value. There must be four values corresponding to thin,
normal, thick, and very thick lines.
force_ltr
force_ltr no
No support BIDI (bidirectional text),
to select a substring of an RTL-shaped string, you will get the character that would be there had the
the string been LTR.
default behavior is useful in with a filter to reverse the word order, manipulating RTL glyphs,
so this option is provided to turn it off.
Used FriBidi to get BIDI support
CURSOR CUSTOMIZATION
cursor
cursor #cccccc
Default cursor color
cursor_text_color
cursor_text_color #111111
Choose the color of text under the cursor. If you want it rendered with the background color of the cell un-
derneath instead, use the special keyword: background
cursor_shape
cursor_shape block
The cursor shape can be one of (block, beam, underline). When reloading the config this will be
changed only if the cursor shape has not been set by the program running in the terminal.
cursor_beam_thickness
cursor_beam_thickness 1.5
Defines the thickness of the beam cursor (in pts)
cursor_underline_thickness
cursor_underline_thickness 2.0
Defines the thickness of the underline cursor (in pts)
cursor_blink_interval
cursor_blink_interval -1
The interval (in seconds) at which to blink the cursor. Set to zero to disable blinking. Negative values mean
use system default. Note that numbers smaller than repaint_delay 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
scrollback_lines
scrollback_lines 2000
Number of lines of history to keep in memory for scrolling back. Memory is allocated on demand. Negative num-
bers 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 cre-
ated 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 pro-
gram. 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 cur-
rent cursor position.
scrollback_pager_history_size
scrollback_pager_history_size 0
Separate scrollback history size, used only for browsing the scrollback buffer (in MB). This separate buffer
is not available for interactive scrolling but will be piped to the pager program when viewing 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 text, unformatted text. A value of zero or less dis-
ables 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
Modify the amount scrolled by the mouse wheel. Note this is only used for low precision scrolling devices,
not for high precision scrolling on platforms such as macOS and Wayland. Use negative numbers to change
scroll direction.
touch_scroll_multiplier
touch_scroll_multiplier 1.0
Modify the amount scrolled by a touchpad. Note this is only used for high precision scrolling devices on
platforms such as macOS and Wayland. Use negative numbers to change scroll direction.
MOUSE
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, single, double, curly
open_url_with
open_url_with default
The program with which to open URLs that are clicked on. The special value default means to use the operating
system's default URL handler.
url_prefixes
url_prefixes http https file ftp gemini irc gopher mailto news git
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 underline and the mouse cursor becomes a
hand over them. Even if this option 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 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 clipboard, simply 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 selections. You can instead specify a name such as a1 to copy to a private kitty buffer
instead. Map a shortcut with the paste_from_buffer action to paste from this private buffer. For example:
map cmd+shift+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.
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 selections. 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.
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 remapped to perform arbitrary actions. The syntax for doing so is:
mouse_map button-name event-type modes action
Where button-name is one of left, middle, right or 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 number
b1 ... b8 can be used to refer to upto eight buttons on a mouse.
event-type is one press, release, doublepress, triplepress, click and doubleclick. modes indicates whether
the action is performed when the mouse is grabbed by the program running in the terminal, or not. It can have
one or more or the values, grabbed,ungrabbed. 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 disam-
biguate from double and triple presses.
You can run kitty with the kitty --debug-input command line option to see mouse events. See the builtin ac-
tions below to get a sense of what is possible.
To unmap an action map it to no-op. For example, to disable opening of URLs with a plain click:
mouse_map left click ungrabbed no-op
Once a selection is started, releasing the button that started it will automatically end it and no release
event will be dispatched.
Click the link under the mouse cursor when no selection is created
mouse_map left click ungrabbed mouse_click_url_or_select
Click the link under the mouse cursor when no selection is created even if grabbed
mouse_map shift+left click grabbed,ungrabbed mouse_click_url_or_select
Click the link under the mouse cursor
mouse_map ctrl+shift+left release grabbed,ungrabbed mouse_click_url
Variant with ctrl+shift is present because the simple click based version 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 re-
lease event is used to open a URL.
Paste from the primary selection

PERFORMANCE TUNING
repaint_delay
repaint_delay 10
Delay (in milliseconds) between screen updates. Decreasing it, increases frames-per-second (FPS) at the cost
of more CPU usage. The default 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, repaint_delay is ignored.
input_delay
input_delay 3
Delay (in milliseconds) before input from the program running in the terminal is processed. Note that de-
creasing it will increase responsiveness, 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 tearing (-
https://en.wikipedia.org/wiki/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.
BELL
enable_audio_bell
enable_audio_bell yes
Enable/disable the audio bell. Useful in environments that require silence.
visual_bell_duration
visual_bell_duration 0.0
Visual bell duration. Flash the screen when a bell occurs for the specified number of seconds. Set to zero to
disable.
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 yes
Show a bell symbol on the tab if a bell occurs in one of the windows in the tab and the window is not the
currently focused window
command_on_bell
command_on_bell none
Program to run when a bell occurs.
WINDOW LAYOUT
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 alphabet-
ical 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 windows. The cells value is used for
horizontal resizing and the lines value 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 visible. 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 minimum needed borders for inactive windows
are drawn. That is only the borders that separate the inactive window from a neighbor. Note that setting a
non-zero window margin 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 (in pts) to use when only a single window is visible. 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 vertical
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 vertical 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 option. Using
a value of center means the cell area will be placed centrally. A value of top-left means the padding will be
on only the bottom 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 occurred
inactive_text_alpha
inactive_text_alpha 1.0
Fade the text in inactive windows by the specified amount (a number between 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 manager/oper-
ating system. Note that the effects of changing this setting when reloading config are undefined.
resize_debounce_time
resize_debounce_time 0.1
The time (in seconds) to wait before redrawing the screen when a resize event is received. 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 win-
dow 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 window 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
an 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.
confirm_os_window_close
confirm_os_window_close 0
Ask for confirmation when closing an OS window or a tab that has at least this number of kitty windows in it.
A value of zero disables confirmation. This confirmation also applies to requests to quit the entire applica-
tion (all OS windows, via the quit action).
TAB BAR
tab_bar_edge
tab_bar_edge bottom
Which 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 and the second number is the margin between the tab bar and the contents of the cur-
rent tab.
tab_bar_style
tab_bar_style fade
The tab bar style, can be one of: fade, separator, powerline, or hidden. In the fade style, each tab's edges
fade into the background color, in the separator style, tabs are separated by a configurable separator, and
the powerline shows the tabs as a continuous line. If you use the hidden style, 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_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 controls how much the corresponding cell fades into the background, with zero be-
ing 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, or 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 ac-
tivity.
tab_title_template
tab_title_template "{title}"
A template to render the tab title. The default just renders the title. 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}. In addition you can use {layout_name} for the cur-
rent layout name and {num_windows} for the number of windows in the tab. 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 di-
rectives, for example: {fmt.fg.red}red{fmt.fg.default}normal{fmt.bg._00FF00}green bg{fmt.bg.normal}. Simi-
larly, for bold and italic: {fmt.bold}bold{fmt.nobold}normal{fmt.italic}italic{fmt.noitalic}.
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, inac-
tive_tab_background, inactive_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 background color.
COLOR SCHEME
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 0 and 1, where 1 is opaque and 0 is fully transparent. This
will only work if supported 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. This is 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 back-
ground color in the editor color scheme. Or use the escape 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 setting 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 or scale the background image.
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 keyboard shortcuts (ctrl+shift+a>m and
ctrl+shift+a>l) or the remote control facility. Changing this setting 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. The tint is applied only under the text area,
not margin/borders. Makes it easier to read the text. Tinting is done using the current background color for
each window. This setting 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_foreground #000000
The foreground for text selected with the mouse. A value of none means to leave the color unchanged.
selection_background

ADVANCED
shell
shell .
The shell program to execute. The default value of . means to use whatever 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 to ensure that the
shell starts in interactive mode and reads its startup rc files.
editor
editor .
The console editor to use when editing the kitty config file or similar tasks. A value of . means to use the
environment variables VISUAL and EDITOR in that order. Note that this environment variable has to be set not
just in your shell startup scripts but system-wide, otherwise kitty will not see it.
close_on_child_death
close_on_child_death no
Close the window when the child process (shell) exits. If no (the default), the terminal will remain open
when the child exits as long as there are still processes outputting to the terminal (for example disowned or
backgrounded processes). If 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 std-
out/stderr/stdin no longer work.
allow_remote_control
allow_remote_control no
Allow other programs to control kitty. If you turn this on other programs can control all aspects of kitty,
including sending text to kitty windows, opening new windows, closing windows, reading the content of win-
dows, etc. Note that this even works over ssh connections. You can chose to either allow any program running
within kitty to control it, with yes or only programs that connect to the socket specified with the kitty
--listen-on command line option, if you use the value socket-only. The latter is useful if you want to pre-
vent programs running on a remote computer over ssh from controlling kitty. Changing this option by reloading
the config will only affect newly created windows.
listen_on
listen_on none
Tell kitty to listen to the specified unix/tcp socket for remote control connections. Note that this will ap-
ply to all kitty instances. It can be overridden by the kitty --listen-on command line flag. This option ac-
cepts only UNIX sockets, such as unix:${TEMP}/mykitty or (on Linux) unix:@mykitty. Environment variables are
expanded. If {kitty_pid} is present then it is replaced by the PID of the kitty process, otherwise the PID of
the kitty process is appended to the value, with a hyphen. This option is ignored unless you also set
allow_remote_control to enable remote control. See the help for kitty --listen-on for more details. Changing
this option by reloading the config is not supported.
env
env
Specify environment variables to set in all child processes. Note that environment variables are expanded re-
cursively, so if you use:
env MYVAR1=a
env MYVAR2=${MYVAR1}/${HOME}/b
The value of MYVAR2 will be a//b.
update_check_interval
update_check_interval 24
Periodically check if an update to kitty is available. If an update is found a system notification is dis-
played informing you of the available update. The default is to check every 24 hrs, set to zero to disable.
Changing this option by reloading the config is not supported.
startup_session
startup_session none
Path to a session file to use for all kitty instances. Can be overridden by using the kitty --session command
line option for individual instances. See sessions in the kitty documentation for details. Note that relative
paths are interpreted with respect to the kitty config directory. Environment variables in the path are ex-
panded. Changing this option by reloading the config is not supported.
clipboard_control
clipboard_control write-clipboard write-primary
Allow programs running in kitty to read and write from the clipboard. You can control exactly which actions
are allowed. The set of possible actions is: write-clipboard read-clipboard write-primary read-primary. You
can additionally specify no-append to disable kitty's protocol extension for clipboard concatenation. The de-
fault is to allow writing to the clipboard and primary selection with concatenation enabled. Note that en-
abling the read functionality is a security risk as it means that any program, even one running on a remote
server via SSH can read your clipboard.
allow_hyperlinks
allow_hyperlinks yes
Process hyperlink (OSC 8) escape sequences. If disabled OSC 8 escape sequences are ignored. Otherwise they
become clickable links, that you can click by holding down ctrl+shift and clicking with the mouse. The spe-
cial value of ask means that kitty will ask before opening the link.
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 chang-
ing it to is, various things from key-presses, to colors, to various advanced features may not work. Changing
this option by reloading the config will only affect newly created windows.
OS SPECIFIC TWEAKS
wayland_titlebar_color
wayland_titlebar_color system
Change 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
background 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
Change the color of the kitty window's titlebar on macOS. A value of system means to use the default system
color, a value of background means to use the background color of the currently active window and finally you
can use an arbitrary color, such as #12af59 or red. WARNING: This option works by using a hack, as there is
no proper Cocoa API for it. It sets the background color of the entire window and makes the titlebar trans-
parent. As such it is incompatible 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. With this set to no, kitty will use the macOS native Option+Key = unicode
character behavior. 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. Changing this setting by reloading the config is not supported.
macos_hide_from_tasks
macos_hide_from_tasks no
Hide the kitty window from running tasks (+Tab) on macOS. Changing this setting 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. 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 setting by
reloading the config will only affect newly created 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. 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 traditional full-screen transition, that is faster, but less pretty.
macos_show_window_title_in
macos_show_window_title_in all
Show or hide the window title in the macOS window or menu-bar. 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 cur-
rently active window in the macOS menu-bar, making use of otherwise wasted space. all will show the title ev-
erywhere and none hides the title in the window and the menu-bar.
macos_custom_beam_cursor
macos_custom_beam_cursor no
Enable/disable custom mouse cursor for macOS that is easier to see on both light and dark backgrounds. WARN-
ING: this might make your mouse cursor invisible on dual GPU machines. Changing this setting by reloading the
config is not supported.
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 setting by reloading the config is not supported.
KEYBOARD SHORTCUTS
Keys are identified by their lowercase unicode characters. For example: a for the A key, [ for the
left square bracket key, etc. For function keys, such as Enter or Escape the names are present at functional.
For a list of modifier names, see: GLFW mods
On Linux use XKB key names to bind keys that are not supported by GLFW. See XKB keys for a list
of key names. The name to use is the part after the XKB_KEY_ prefix. Only use an XKB key
name for keys that are not known as GLFW keys.
Use raw system key codes to map keys, 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: 65 native_code: 0x61 action: PRESS mods: 0x0 text: 'a'
The key name for the A key is 0x61 use it with:
map ctrl+0x61 something
To map ctrl+a to something.
Use the special action no_op to unmap a keyboard shortcut that is assigned in the default configuration:
map kitty_mod+space no_op
Combine multiple actions to be triggered by a single shortcut, using
map key combine action1 action2 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
Use multi-key shortcuts use
map key1>key2>key3 action
For example:
map ctrl+f>2 set_font_size 20
kitty_mod
kitty_mod ctrl+shift
The value of kitty_mod is used as the modifier for all default shortcuts, change it in
kitty.conf to change the modifiers for all the default shortcuts.
clear_all_shortcuts
clear_all_shortcuts no
have kitty remove all shortcut definition seen up to this point. Useful, for instance, to remove the
default shortcuts.
kitten_alias
kitten_alias hints hints --hints-offset=0
Create aliases for kitten names, this allows overriding the defaults for kitten options and can also
be used to shorten repeated mappings of the same kitten with a specific group of options. For example, the
above alias changes the default value of kitty +kitten hints --hints-offset to zero for all mappings, includ-
ing the builtin ones.
Clipboard
Copy to clipboard map ctrl+shift+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 interrupt 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
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
Pass the contents of the current selection to any program using 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
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

launch function. For example, 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 programs, see launch.
Window management
New window map ctrl+shift+enter new_window
map cmd+enter new_window
Open a new window running an arbitrary program, for example:
map kitty_mod+y launch mutt
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
Open a new window that is allowed to control kitty via the kitty remote control facility by prefixing
the command line with @. Any programs running in that window will be allowed to control kitty. For example:
map ctrl+enter launch --allow-remote-control some_program
Open a new window next to the currently active window or as the first window, with:
map ctrl+n launch --location=neighbor some_program
map ctrl+f launch --location=first some_program
For more details, see launch.

Reset background opacity map ctrl+shift+a>d set_background_opacity default
Reset the terminal map ctrl+shift+delete clear_terminal reset active
map cmd+option+r clear_terminal reset active
You can create shortcuts to clear/reset the terminal. For example:
# Reset the terminal map kitty_mod+f9 clear_terminal reset active
# Clear the terminal screen by erasing all contents
map kitty_mod+f10 clear_terminal clear active
# Clear the terminal scrollback by erasing it
map kitty_mod+f11 clear_terminal scrollback active
# Scroll the contents of the screen into the scrollback
map kitty_mod+f12 clear_terminal scroll active
To operate on all windows all instead of active.
Map Ctrl+L to both scroll the current screen contents into the scrollback buffer and
clear 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
Reload kitty.conf map ctrl+shift+f5 load_config_file
map cmd+control+, load_config_file
Reload kitty.conf, applying any changes since the last time it was loaded. Note that a handful of settings
cannot be dynamically changed and require a full restart of kitty. You can also map a keybinding to load a
different config file, for example:

Miscellaneous
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 combination. 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 characters
(or you can just input the unicode characters directly as UTF-8 text). The first argument to send_text is the
keyboard modes in which to activate the shortcut. The possible values are normal or application or kitty or a
comma separated combination of them. The special keyword all means all modes. The modes normal and applica-
tion refer to the DECCKM cursor key mode for terminals, and kitty refers to the special kitty extended key-
board protocol.
Another example, that outputs a word and then moves the cursor to the start of the line (same as pressing the
Home key):
map ctrl+alt+a send_text normal Word\x1b[H
map ctrl+alt+a send_text application Word\x1bOH
SAMPLE KITTY.CONF
