Name

       kitty.conf - Configuration file for kitty

Overview

       kitty   is   highly   customizable,  everything  from  keyboard  shortcuts,  to  rendering
       frames-per-second. See below for an overview of all customization 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 with kill -SIGUSR1
       $KITTY_PID. 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.

       Lines can be split by starting the next line with the \ character.  All leading whitespace
       and the \ character are removed.

       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.  A  special environment variable KITTY_OS is available, to detect the operating
       system. It is linux, macos or bsd.   Also,  you  can  use  globinclude  to  include  files
       matching  a  shell  glob  pattern and envinclude to include configuration from environment
       variables. For example:

          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.

Fonts

       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 variants.  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 string been LTR. For
       example, assuming the Hebrew word ירושלים, selecting the  character  that  on  the  screen
       appears to be ם actually writes into the selection buffer the character י. 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

       Has no default values. Example values are shown below:

          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

       Has no default values. Example values are shown below:

          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 character 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 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

       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

       Has no default values. Example values are shown below:

          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  easily 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  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 underline 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 arrive at a pixel  value.   There  must  be
       four values corresponding to thin, normal, thick, and very thick lines.

       undercurl_style

          undercurl_style thin-sparse

       The   style   with   which   undercurls   are   rendered.   This  option  takes  the  form
       (thin|thick)-(sparse|dense). Thin and thick control the thickness of the undercurl. Sparse
       and  dense  control how often the curl oscillates. With sparse the curl will peak once per
       character, with dense twice.

       text_composition_strategy

          text_composition_strategy platform

       Control how kitty composites text glyphs onto the background color. The default  value  of
       platform  tries  for text rendering as close to "native" for the platform kitty is running
       on as possible.

       A value of legacy uses the old (pre kitty 0.28) strategy for how  glyphs  are  composited.
       This  will  make  dark  text  on  light  backgrounds  look  thicker and light text on dark
       backgrounds thinner. It might also make some text appear like the strokes are uneven.

       You can fine tune the actual contrast curve used for glyph composition by specifying up to
       two space-separated numbers for this setting.

       The  first  number  is  the gamma adjustment, which controls the thickness of dark text on
       light backgrounds. Increasing the value will make text appear thicker.  The default  value
       for this is 1.0 on Linux and 1.7 on macOS.  Valid values are 0.01 and above. The result is
       scaled based on the luminance difference between the background and the  foreground.  Dark
       text  on  light backgrounds receives the full impact of the curve while light text on dark
       backgrounds is affected very little.

       The second number is an additional multiplicative contrast. It is percentage ranging  from
       0 to 100. The default value is 0 on Linux and 30 on macOS.

       If  you  wish to achieve similar looking thickness in light and dark themes, a good way to
       experiment is start by setting the value to 1.0 0 and use a dark theme.  Then  adjust  the
       second  parameter  until  it looks good. Then switch to a light theme and adjust the first
       parameter until the perceived thickness matches the dark theme.

       text_fg_override_threshold

          text_fg_override_threshold 0

       The minimum accepted difference in luminance between the foreground and background  color,
       below  which  kitty will override the foreground color. It is percentage ranging from 0 to
       100. If the difference in luminance  of  the  foreground  and  background  is  below  this
       threshold, the foreground color will be set to white if the background is dark or black if
       the background is light. The default value is 0, which means no overriding  is  performed.
       Useful  when working with applications that use colors that do not contrast well with your
       preferred color scheme.

       WARNING: Some programs use characters (such as block characters) for graphics display  and
       may  expect  to be able to set the foreground and background to the same color (or similar
       colors).  If you see unexpected stripes, dots, lines, incorrect color, no color where  you
       expect    color,    or    any    kind    of    graphic   display   problem   try   setting
       text_fg_override_threshold to 0 to see if this is the cause of the problem.

Cursor customization

       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
       cursor colors are modified if the cell background and  foreground  colors  have  very  low
       contrast.  Note that some themes set this value, so if you want to override it, place your
       value after the lines where the theme file is included.

       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 keyword: background. Note that if cursor is
       set to none then this option is ignored. Note that some themes set this value, so  if  you
       want to override it, place your value after the lines where the theme file is included.

       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 default 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  minimum  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

       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 example, 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  viewing  scrollback buffer in a separate window. The
       current implementation stores the data in UTF-8, so approximately 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 Wayland. 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 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,
       straight, double, curly, dotted, dashed.

       open_url_with

          open_url_with default

       The  program  to  open clicked URLs. The special value default will first look for any URL
       handlers defined via the Scripting the mouse click facility 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 underline and the mouse
       cursor becomes a hand over  them.  Even  if  this  option  is  disabled,  URLs  are  still
       clickable.  See also the underline_hyperlinks option to control how hyperlinks (as opposed
       to plain text URLs) are displayed.

       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.  Additionally,
       newlines are allowed (but stripped). This is to accommodate programs such as mutt that add
       hard line breaks even for continued lines.  \n can be added to this option to disable this
       behavior. Special characters can be  specified  using  backslash  escapes,  to  specify  a
       backslash use a double backslash.

       show_hyperlink_targets

          show_hyperlink_targets no

       When  the  mouse  hovers  over  a  terminal  hyperlink,  show  the actual URL that will be
       activated when the hyperlink is clicked.

       underline_hyperlinks

          underline_hyperlinks hover

       Control how hyperlinks are underlined. They can  either  be  underlined  on  mouse  hover,
       always  (i.e.  permanently  underlined) or never which means that kitty will not apply any
       underline styling to hyperlinks.  Uses  the  url_style  and  url_color  settings  for  the
       underline  style.  Note  that  reloading the config and changing this value to/from always
       will only affect text subsequently received by kitty.

       copy_on_select

          copy_on_select no

       Copy to clipboard or a private buffer on select. With this  set  to  clipboard,  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 example:

          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,confirm

       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).

       replace-dangerous-control-codes
              Replace dangerous control codes from pasted text, without confirmation.

       replace-newline
              Replace the newline character from pasted text, without confirmation.

       confirm:
              Confirm  the  paste if the text to be pasted contains any terminal control codes as
              this can be dangerous, leading to code execution if the  shell/program  running  in
              the terminal does not properly handle these.

       confirm-if-large
              Confirm  the  paste if it is very large (larger than 16KB) as pasting large amounts
              of text into shells can be very slow.

       filter:
              Run the filter_paste() function from the file paste-actions.py in the kitty  config
              directory  on  the  pasted text. The text returned by the function will be actually
              pasted.

       no-op: Has no effect.

       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. 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

       Characters considered part of a word  when  extending  the  selection  forward  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 directions.

       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.  On
       macOS, this will also cause the OS Window under the mouse to be focused automatically when
       the mouse enters it.

       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.

       default_pointer_shape

          default_pointer_shape beam

       The default shape of the mouse pointer.

       pointer_shape_when_dragging

          pointer_shape_when_dragging beam

       The default shape of the mouse pointer when dragging across text.

   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 a button, map it to nothing. For example, to disable opening of  URLs
       with a plain click:

          mouse_map left click ungrabbed

       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 instance, 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 integration 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  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 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

       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. If you would like to select the word
       at the point and  then  extend  to  the  rest  of  the  line,  change  line_from_point  to
       word_and_line_from_point.

       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. If you would  like
       to  select  the  word  at  the  point  and  then  extend  to  the rest of the line, change
       line_from_point to word_and_line_from_point.

       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.

Performance tuning

       repaint_delay

          repaint_delay 10

       Delay between screen updates (in milliseconds). 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, this option is ignored.

       input_delay

          input_delay 3

       Delay  before  input  from  the  program  running  in  the  terminal  is   processed   (in
       milliseconds). Note that decreasing 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 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.

Terminal bell

       enable_audio_bell

          enable_audio_bell yes

       The audio bell. Useful to disable it in environments that require silence.

       visual_bell_duration

          visual_bell_duration 0.0

       The visual bell duration (in seconds). Flash  the  screen  when  a  bell  occurs  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 window 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)

       linux_bell_theme

          linux_bell_theme __custom

       The  XDG  Sound  Theme kitty will use to play the bell sound. Defaults to the custom theme
       name used by GNOME and Budgie, falling back to the default freedesktop theme  if  it  does
       not  exist. This option may be removed if Linux ever provides desktop-agnostic support for
       setting system sound themes.

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 OS Window size will be remembered so that new instances of kitty will have
       the  same  size  as the previous instance.  If disabled, the OS Window will initially have
       size configured by initial_window_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 alphabetical 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 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 borders that separate the
       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  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.

       single_window_padding_width

          single_window_padding_width -1

       The window padding to use when only a single window is visible (in pts).  Negative  values
       will  cause  the value of window_padding_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.

       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 only at 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 and titlebar-and-corners can be used to  only  hide  the  titlebar  and  the
       rounded  corners.  Whether this works and exactly what effect it has depends on the window
       manager/operating system. Note that the effects of changing  this  option  when  reloading
       config   are   undefined.   When   using   titlebar-only,   it   is  useful  to  also  set
       window_margin_width and placement_strategy to prevent the rounded  corners  from  clipping
       text. Or use titlebar-and-corners.

       window_logo_path

          window_logo_path none

       Path  to  a  logo image. Must be in PNG format. Relative paths are interpreted 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 being fully faded and
       one being fully opaque.

       resize_debounce_time

          resize_debounce_time 0.1 0.5

       The time to wait (in seconds) before asking the program running in  kitty  to  resize  and
       redraw  the  screen  during a live resize of the OS window, when no new resize events have
       been received, i.e. when resizing is either paused or  finished.   On  platforms  such  as
       macOS,  where  the  operating  system sends events corresponding to the start and end of a
       live resize, the second number is used for redraw-after-pause since kitty can  distinguish
       between  a  pause  and  end  of  resizing. On such systems the first number is ignored and
       redraw is immediate after end of resize. On other systems only the first number is used so
       that  kitty  is  "ready"  quickly  after  the end of resizing, while not also continuously
       redrawing, to save energy.

       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  confirmation.  This  confirmation  also  applies  to requests to quit the entire
       application (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

       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 second 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 controls 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_max_length

          tab_title_max_length 0

       The maximum number of cells that can be used to render the text in a tab.  A value of zero
       means that no limit is applied.

       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 usable 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  (a window group is a window and all of its overlay
              windows) in the tab.

       tab.active_wd
              The working directory of  the  currently  active  window  in  the  tab  (expensive,
              requires  syscall).  Use  active_oldest_wd  to  get  the  directory  of  the oldest
              foreground process rather than the newest.

       tab.active_exe
              The name of the executable running in the foreground of the currently active window
              in  the  tab  (expensive,  requires  syscall). Use active_oldest_exe for the oldest
              foreground process.

       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}normal{fmt.italic}italic{fmt.noitalic}.   Note  that
       for  backward  compatibility, 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, 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.

       tab_bar_margin_color

          tab_bar_margin_color none

       Color  for  the  tab  bar margin area. Defaults to using the terminal background color for
       margins above and below the tab bar. For side margins the default color is chosen to match
       the background color of the neighboring tab.

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 zero and one, where one is opaque and zero
       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,  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 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. When using a low  value
       for this setting, it is desirable that you set the background color to a color the matches
       the general color of the desktop background, for best text  rendering.   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_blur

          background_blur 0

       Set  to  a  positive  value  to  enable  background blur (blurring of the visuals behind a
       transparent  window)  on   platforms   that   support   it.   Only   takes   effect   when
       background_opacity  is  less  than  one.  On macOS, this will also control the blur radius
       (amount of blurring). Setting it to too high a value will cause severe performance  issues
       and/or  rendering  artifacts.   Usually,  values  up to 64 work well. Note that this might
       cause performance issues, depending on how the platform implements it, so use  with  care.
       Currently supported on macOS and KDE under X11.

       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, centered or cscaled. The scaled and  cscaled  values  scale
       the image to the window size, with cscaled preserving the image aspect ratio.

       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 option by
       reloading the config is not supported.

       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 current background color for each window. This
       option  applies only if background_opacity is set and transparent windows are supported or
       background_image is set.

       background_tint_gaps

          background_tint_gaps 1.0

       How much to tint the background image at the window gaps by the  background  color,  after
       applying  background_tint.  Since  this  is multiplicative with background_tint, it can be
       used to lighten the tint over the window gaps for a separated look.

       dim_opacity

          dim_opacity 0.4

       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
       selection_foreground to none will cause the foreground color to be  used  unchanged.  Note
       that these colors can be overridden by the program running 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  remaining  240  colors  as  color16  to
       color255.

       color0, color8

          color0 #000000

          mark3_foreground black

       Color for marks of type 3

       mark3_background

          mark3_background #f274bc

       Color for marks of type 3 (violet)

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 and --interactive to ensure that the shell starts in interactive mode
       and reads its startup rc files. Environment variables are expanded in this setting.

       editor

          editor .

       The terminal based text editor (such as vim or nano) to use when editing 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 disowned 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

       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
       example:

          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:

          kitten @ --help

       A set of actions to be allowed when no password is sent can be specified 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 command.  For example:

          remote_control_password "my passphrase" my_rc_command_checker.py

       Relative  paths  are  resolved  from  the  kitty configuration directory.  See Customizing
       authorization with your own program for details.

       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  windows,  etc.  Note  that  this  even  works  over  SSH
       connections. The default 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 unconditionally.
              Requests received over the TTY are denied.  See listen_on.

       socket Remote control requests  received  over  a  socket  are  accepted  unconditionally.
              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 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.
       For  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  temporary
       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 appended to the value, with a  hyphen.  For  TCP
       sockets  such  as  tcp:localhost:0  a  random  port is always used even if a non-zero port
       number is specified.  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

       Specify the environment variables to be set in all child processes. Using 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

       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  relative to the kitty config directory. Note that
       reloading the config will only affect windows created after the reload.

       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 official binary builds. Distro packages or source  builds  do  not  do  update
       checking. 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 =none command line option for individual instances. See  Startup  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  expanded.
       Changing 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 512

       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

       The  password  that  can  be  supplied  to  the  file transfer kitten to skip the transfer
       confirmation prompt. This should only be  used  when  initiating  transfers  from  trusted
       computers,  over  trusted  networks  or  encrypted  transports,  as it allows any programs
       running on the remote machine 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  previous  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,  no-sudo.  See Shell
       integration for details.

       allow_cloning

          allow_cloning ask

       Control whether programs running in the terminal can request new windows  to  be  created.
       The  canonical  example  is  clone-in-kitty. By default, kitty will ask for permission for
       each clone request.  Allowing  cloning  unconditionally  gives  programs  running  in  the
       terminal  (including  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 automatically.

       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. Only the first valid
       match, in the order specified, is sourced.

       notify_on_cmd_finish

          notify_on_cmd_finish never

       Show   a   desktop   notification   when   a   long-running   command   finishes    (needs
       shell_integration).  The possible values are:

       never  Never send a notification.

       unfocused
              Only send a notification when the window does not have keyboard focus.

       invisible
              Only  send  a notification when the window both is unfocused and not visible to the
              user, for example, because it is in an  inactive  tab  or  its  OS  window  is  not
              currently active.

       always Always send a notification, regardless of window state.

       There are two optional arguments:

       First,  the minimum duration for what is considered a long running command. The default is
       5 seconds. Specify a second argument to set the duration. For example: invisible  15.   Do
       not  set  the value too small, otherwise a command that launches a new OS Window and exits
       will spam a notification.

       Second, the action to perform. The default is notify. The possible values are:

       notify Send a desktop notification.

       bell   Ring the terminal bell.

       command
              Run a custom command. All subsequent arguments are the cmdline to run.

       Some more examples:

          # Send a notification when a command takes more than 5 seconds in an unfocused window
          notify_on_cmd_finish unfocused
          # Send a notification when a command takes more than 10 seconds in a invisible window
          notify_on_cmd_finish invisible 10.0
          # Ring a bell when a command takes more than 10 seconds in a invisible window
          notify_on_cmd_finish invisible 10.0 bell
          # Run 'notify-send' when a command takes more than 10 seconds in a invisible window
          notify_on_cmd_finish invisible 10.0 command notify-send job finished

       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 reloading the config will only affect newly created windows.

       forward_stdio

          forward_stdio no

       Forward STDOUT and STDERR of the kitty process to child processes as  file  descriptors  3
       and  4.  This  is  useful  for  debugging as it allows child processes to print to kitty's
       STDOUT directly. For example, echo hello world >&3 in a shell will  print  to  the  parent
       kitty's  STDOUT.  When  enabled,  this  also  sets the KITTY_STDIO_FORWARDED=3 environment
       variable so child processes know about the forwarding.

       menu_map

       Specify entries for various menus in kitty. Currently only the global menubar on macOS  is
       supported. For example:

          menu_map global "Actions::Launch something special" launch --hold --type=os-window sh -c "echo hello world"

       This will create a menu entry named "Launch something special" in an "Actions" menu in the
       macOS global menubar.  Sub-menus can be created by adding more levels separated by the  ::
       characters.

Os specific tweaks

       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 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

       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  arbitrary  color, such as #12af59 or red. WARNING: This option works by
       using 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 entire window and makes the titlebar
       transparent. 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 on macOS. With this set to no, kitty will use the macOS
       native Option+Key to enter  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. Note that kitty itself always treats Option the same as Alt.
       This means you  cannot  use  this  option  to  configure  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.

       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. Note that in modern kitty, this
       option is obsolete (although still supported).  Consider  using  text_composition_strategy
       instead.

       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 maximum 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 invisible 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.

Keyboard shortcuts

       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 (control, ), shift (), alt (opt, option, ), super (cmd, command, ).

       Simple shortcut mapping is done with the map  directive.  For  full  details  on  advanced
       mapping  including  modal  and per application maps, see Making your keyboard dance.  Some
       quick examples to illustrate common tasks:

          # unmap a keyboard shortcut, passing it to the program running in kitty
          map kitty_mod+space
          # completely ignore a keyboard event
          map ctrl+alt+f1 discard_event
          # combine multiple actions
          map kitty_mod+e combine : new_window : next_layout
          # multi-key shortcuts
          map ctrl+x>ctrl+y>z action

       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

       Has no default values. Example values are shown below:

          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 duplication:

          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

       Has no default values. Example values are shown below:

          kitten_alias hints hints --hints-offset=0

       Like   action_alias  above,  but  specifically  for  kittens.  Generally,  prefer  to  use
       action_alias. This option is a legacy version, present  for  backwards  compatibility.  It
       causes  all invocations of the aliased kitten 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  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
          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

   Scrolling
       Scroll line up

          map ctrl+shift+up scroll_line_up
          map ctrl+shift+k scroll_line_up
          map opt+cmd+page_up scroll_line_up 🍎
          map cmd+up scroll_line_up 🍎

       Scroll line down

          map ctrl+shift+down scroll_line_down
          map ctrl+shift+j scroll_line_down
          map opt+cmd+page_down scroll_line_down 🍎
          map cmd+down scroll_line_down 🍎

       Scroll page up

          map ctrl+shift+page_up scroll_page_up
          map cmd+page_up scroll_page_up 🍎

       Scroll page down

          map ctrl+shift+page_down scroll_page_down
          map cmd+page_down scroll_page_down 🍎

       Scroll to top

          map ctrl+shift+home scroll_home
          map cmd+home scroll_home 🍎

       Scroll to bottom

          map ctrl+shift+end scroll_end
          map cmd+end scroll_end 🍎

       Scroll to previous shell prompt

          map ctrl+shift+z scroll_to_prompt -1

       Use  a  parameter  of  0  for scroll_to_prompt to scroll to the last jumped 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  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 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 example:

          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
          map cmd+n new_os_window 🍎

       Works like new_window above, except that it opens a top-level OS window. In particular you
       can use new_os_window_with_cwd to open a window with the current working directory.

       Close window

          map ctrl+shift+w close_window
          map shift+cmd+d close_window 🍎

       Next window

          map ctrl+shift+] next_window

       Previous window

          map ctrl+shift+[ previous_window

       Move window forward

          map ctrl+shift+f move_window_forward

       Move window backward

          map ctrl+shift+b move_window_backward

       Move window to top

          map ctrl+shift+` move_window_to_top

       Start resizing window

          map ctrl+shift+r start_resizing_window
          map cmd+r start_resizing_window 🍎

       First window

          map ctrl+shift+1 first_window
          map cmd+1 first_window 🍎

       Second window

          map ctrl+shift+2 second_window
          map cmd+2 second_window 🍎

       Third window

          map ctrl+shift+3 third_window
          map cmd+3 third_window 🍎

       Fourth window

          map ctrl+shift+4 fourth_window
          map cmd+4 fourth_window 🍎

       Fifth window

          map ctrl+shift+5 fifth_window
          map cmd+5 fifth_window 🍎

       Sixth window

          map ctrl+shift+6 sixth_window
          map cmd+6 sixth_window 🍎

       Seventh window

          map ctrl+shift+7 seventh_window
          map cmd+7 seventh_window 🍎

       Eighth window

          map ctrl+shift+8 eighth_window
          map cmd+8 eighth_window 🍎

       Ninth window

          map ctrl+shift+9 ninth_window
          map cmd+9 ninth_window 🍎

       Tenth window

          map ctrl+shift+0 tenth_window

       Visually select and focus window

          map ctrl+shift+f7 focus_visible_window

       Display  overlay  numbers  and alphabets on the window, and switch the focus to the window
       when you press the key. When there are only  two  windows,  the  focus  will  be  switched
       directly  without  displaying the overlay. You can change the overlay characters and their
       order with option visual_window_select_characters.

       Visually swap window with another

          map ctrl+shift+f8 swap_with_window

       Works like focus_visible_window above, but swaps the window.

   Tab management
       Next tab

          map ctrl+shift+right next_tab
          map shift+cmd+] next_tab 🍎
          map ctrl+tab next_tab

       Previous tab

          map ctrl+shift+left previous_tab
          map shift+cmd+[ previous_tab 🍎
          map ctrl+shift+tab previous_tab

       New tab

          map ctrl+shift+t new_tab
          map cmd+t new_tab 🍎

       Close tab

          map ctrl+shift+q close_tab
          map cmd+w close_tab 🍎

       Close OS window

          map shift+cmd+w close_os_window 🍎

       Move tab forward

          map ctrl+shift+. move_tab_forward

       Move tab backward

          map ctrl+shift+, move_tab_backward

       Set tab title

          map ctrl+shift+alt+t set_tab_title
          map shift+cmd+i set_tab_title 🍎

       You can also create shortcuts to go to specific tabs, with 1 being the first  tab,  2  the
       second tab and -1 being the previously active tab, and any number larger than the last tab
       being the last tab:

          map ctrl+alt+1 goto_tab 1
          map ctrl+alt+2 goto_tab 2

       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
       Next layout

          map ctrl+shift+l next_layout

       You can also create shortcuts to switch to specific layouts:

          map ctrl+alt+t goto_layout tall
          map ctrl+alt+s goto_layout stack

       Similarly, to switch back to the previous layout:

          map ctrl+alt+p last_used_layout

       There is also a toggle_layout action that switches to the named  layout  or  back  to  the
       previous  layout if in the named layout. Useful to temporarily "zoom" the active window by
       switching to the stack layout:

          map ctrl+alt+z toggle_layout stack

   Font sizes
       You can change the font size for all top-level kitty OS windows at  a  time  or  only  the
       current one.

       Increase font size

          map ctrl+shift+equal change_font_size all +2.0
          map ctrl+shift+plus change_font_size all +2.0
          map ctrl+shift+kp_add change_font_size all +2.0
          map cmd+plus change_font_size all +2.0 🍎
          map cmd+equal change_font_size all +2.0 🍎
          map shift+cmd+equal change_font_size all +2.0 🍎

       Decrease font size

          map ctrl+shift+minus change_font_size all -2.0
          map ctrl+shift+kp_subtract change_font_size all -2.0
          map cmd+minus change_font_size all -2.0 🍎

       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.

       Some  useful  functions that can be defined in the shell rc files to perform various kinds
       of clearing of the current window:

          clear-only-screen() {
              printf "\e[H\e[2J"
          }

          clear-screen-and-scrollback() {
              printf "\e[H\e[3J"
          }

          clear-screen-saving-contents-in-scrollback() {
              printf "\e[H\e[22J"
          }

       For instance, using these escape codes, it is 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 ZSH, in ~/.zshrc, add:

          ctrl_l() {
              builtin print -rn -- $'\\r\e[0J\e[H\e[22J' >"$TTY"
              builtin zle .reset-prompt
              builtin zle -R
          }
          zle -N ctrl_l
          bindkey '^l' ctrl_l

       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 shortcuts 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 combination. The text to
       be sent decodes ANSI C escapes so you can use escapes like \e to  send  control  codes  or
       \u21fb  to  send Unicode characters (or you can just input the Unicode characters directly
       as UTF-8 text). You can use 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 activate the shortcut.
       The possible values are normal, application, kitty or a  comma  separated  combination  of
       them.  The modes normal and application 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\e[H
          map ctrl+alt+a send_text application Word\eOH
          # 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

Sample kitty.conf

       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.

       A default configuration file can also be generated by running:

          kitty +runpy 'from kitty.config import *; print(commented_out_default_config())'

       This will print the commented out default config file to STDOUT.
