       kitty.conf - kitty.conf Documentation

       kitty  is  highly  customizable,	everything from	keyboard shortcuts, to
       rendering frames-per-second. See	below for  an  overview	 of  all  cus-
       tomization possibilities.

       You  can	 open  the config file within kitty by pressing	ctrl+shift+f2.
       You can reload the config file within kitty by  pressing	 ctrl+shift+f5
       or  sending kitty the SIGUSR1 signal.  You can also display the current
       configuration by	pressing the ctrl+shift+f6 key.

       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 the kitty --config	option for full	details.

       Comments	 can  be added to the config file as lines starting with the #
       character. This works only if the # character is	the first character in
       the line.

       You  can	 include secondary config files	via the	include	directive.  If
       you use a relative path for include, it is resolved with	respect	to the
       location	 of  the  current config file. Note that environment variables
       are expanded, so	${USER}.conf becomes name.conf if USER=name.  For  ex-

	  include other.conf

       kitty  has  very	powerful font management. You can configure individual
       font faces and even specify special fonts for particular	characters.

       font_family, bold_font, italic_font, bold_italic_font

	  font_family	   monospace
	  bold_font	   auto
	  italic_font	   auto
	  bold_italic_font auto

       You can specify different fonts for the	bold/italic/bold-italic	 vari-
       ants.   To  get a full list of supported	fonts use the kitty list-fonts
       command.	 By default they are derived automatically, by the  OSes  font
       system.	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 11.0

       Font size (in pts)


	  force_ltr no

       kitty does not support BIDI  (bidirectional  text),  however,  for  RTL
       scripts,	 words	are automatically displayed in RTL. That is to say, in
       an RTL script, the words	"HELLO	WORLD"	display	 in  kitty  as	"WORLD
       HELLO",	and  if	you try	to select a substring of an RTL-shaped string,
       you will	get the	character that would be	there had the the string  been
       LTR.  For  example, assuming the	Hebrew word xx"xx(C)xxx, selecting the
       character that on the screen appears to be x actually writes  into  the
       selection  buffer  the character	x.  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.

       adjust_line_height, adjust_column_width

	  adjust_line_height  0
	  adjust_column_width 0

       Change  the  size of each character cell	kitty renders. You can use ei-
       ther numbers, which are interpreted as pixels  or  percentages  (number
       followed	 by %),	which are interpreted as percentages of	the unmodified
       values. You can use negative pixels or percentages less	than  100%  to
       reduce sizes (but this might cause rendering artifacts).


	  adjust_baseline 0

       Adjust  the vertical alignment of text (the height in the cell at which
       text is positioned). You	can use	either numbers,	which are  interpreted
       as  pixels  or  a  percentages (number followed by %), which are	inter-
       preted as the percentage	of the line height. A positive value moves the
       baseline	 up,  and  a negative value moves them down. The underline and
       strikethrough positions are adjusted accordingly.


	  symbol_map 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.  sym-
       bol_map itself can be specified multiple	times.	Syntax is:

	  symbol_map codepoints	Font Family Name


	  disable_ligatures never

       Choose how you want to handle multi-character ligatures.	The default is
       to always render	them.  You can tell kitty to not render	them when  the
       cursor  is  over	 them  by using	cursor to make editing easier, or have
       kitty never render them at all by using always, if you don't like them.
       The  ligature strategy can be set per-window either using the kitty re-
       mote control facility or	by defining shortcuts for  it  in  kitty.conf,
       for example:

	  map alt+1 disable_ligatures_in active	always
	  map alt+2 disable_ligatures_in all never
	  map alt+3 disable_ligatures_in tab cursor

       Note  that  this	refers to programming ligatures, typically implemented
       using the calt OpenType feature.	For disabling general  ligatures,  use
       the font_features setting.


	  font_features	none

       Choose  exactly	which  OpenType	features to enable or disable. This is
       useful as some fonts might have features	worthwhile in a	terminal.  For
       example,	Fira Code Retina includes a discretionary feature, zero, which
       in that font changes the	appearance of the zero (0), to	make  it  more
       easily  distinguishable	from  A.  Fira Code Retina 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

       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

       On  Linux,  these  are read from	the FontConfig database	first and then
       this, setting is	applied, so they can be	configured in a	 single,  cen-
       tral place.

       To  get	the  PostScript	 name  for  a  font,  use  kitty  + list-fonts

	  $ kitty + list-fonts --psnames | grep	Fira
	  Fira Code
	  Fira Code Bold (FiraCode-Bold)
	  Fira Code Light (FiraCode-Light)
	  Fira Code Medium (FiraCode-Medium)
	  Fira Code Regular (FiraCode-Regular)
	  Fira Code Retina (FiraCode-Retina)

       The part	in brackets is the PostScript name.

       Enable alternate	zero and oldstyle numerals:

	  font_features	FiraCode-Retina	+zero +onum

       Enable only alternate zero:

	  font_features	FiraCode-Retina	+zero

       Disable the normal ligatures, but keep the calt feature which (in  this
       font) breaks up monotony:

	  font_features	TT2020StyleB-Regular -liga +calt

       In  conjunction	with force_ltr,	you may	want to	disable	Arabic shaping
       entirely, and only look at their	isolated forms if they show  up	 in  a
       document.  You can do this with e.g.:

	  font_features	UnifontMedium +isol -medi -fina	-init


	  box_drawing_scale 0.001, 1, 1.5, 2

       Change  the sizes of the	lines used for the box drawing unicode charac-
       ters 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.


	  cursor #cccccc

       Default cursor color


	  cursor_text_color #111111

       Choose the color	of text	under the cursor. If you want it rendered with
       the  background	color  of the cell underneath instead, use the special
       keyword:	background


	  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.


	  cursor_beam_thickness	1.5

       Defines the thickness of	the beam cursor	(in pts)


	  cursor_underline_thickness 2.0

       Defines the thickness of	the underline cursor (in pts)


	  cursor_blink_interval	-1

       The interval (in	seconds) at which to blink the cursor. Set to zero  to
       disable	blinking.  Negative  values mean use system default. Note that
       numbers smaller than repaint_delay will be limited to repaint_delay.


	  cursor_stop_blinking_after 15.0

       Stop blinking cursor after the specified	number of seconds of  keyboard
       inactivity.  Set	to zero	to never stop blinking.


	  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 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.


	  scrollback_pager_history_size	0

       Separate	scrollback history size, used only for browsing	the scrollback
       buffer (in MB). This separate buffer is not available  for  interactive
       scrolling  but  will be piped to	the pager program when viewing scroll-
       back buffer in a	separate window. The current implementation stores the
       data in UTF-8, so approximatively 10000 lines per megabyte at 100 chars
       per line, for pure ASCII	text, unformatted text.	A  value  of  zero  or
       less  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 no

       Fill  new space with lines from the scrollback buffer after enlarging a


	  wheel_scroll_multiplier 5.0

       Modify the amount scrolled by the mouse wheel. Note this	is  only  used
       for  low	 precision scrolling devices, not for high precision scrolling
       on platforms such as macOS and Wayland. Use negative numbers to	change
       scroll direction.


	  touch_scroll_multiplier 1.0

       Modify  the  amount  scrolled by	a touchpad. Note this is only used for
       high precision scrolling	devices	on platforms such as  macOS  and  Way-
       land. Use negative numbers to change scroll direction.


	  mouse_hide_wait 3.0

       Hide  mouse  cursor  after the specified	number of seconds of the mouse
       not being used. Set to zero to disable mouse cursor hiding.  Set	 to  a
       negative	 value	to hide	the mouse cursor immediately when typing text.
       Disabled	by default on macOS as getting it to work  robustly  with  the
       ever-changing sea of bugs that is Cocoa is too much effort.

       url_color, url_style

	  url_color #0087bd
	  url_style curly

       The  color and style for	highlighting URLs on mouse-over. url_style can
       be one of: none,	single,	double,	curly


	  open_url_with	default

       The program with	which to open URLs that	are clicked  on.  The  special
       value default means to use the operating	system's default URL handler.


	  url_prefixes http https file ftp gemini irc gopher mailto news git

       The  set	 of  URL  prefixes  to look for	when detecting a URL under the
       mouse cursor.


	  detect_urls yes

       Detect URLs under the mouse. Detected URLs are highlighted with an  un-
       derline and the mouse cursor becomes a hand over	them. Even if this op-
       tion is disabled, URLs are still	clickable.



       Additional characters to	be disallowed from URLs, when  detecting  URLs
       under  the  mouse  cursor. By default, all characters legal in URLs are


	  copy_on_select no

       Copy to clipboard or a private buffer on	select.	With this set to clip-
       board,  simply  selecting text with the mouse will cause	the text to be
       copied to clipboard. Useful on platforms	such as	macOS that do not have
       the  concept of primary selections. You can instead specify a name such
       as a1 to	copy to	a private kitty	buffer instead.	Map  a	shortcut  with
       the  paste_from_buffer  action  to paste	from this private buffer.  For

	  map cmd+shift+v paste_from_buffer a1

       Note that copying to the	clipboard is a security	risk, as all programs,
       including  websites  open  in your browser can read the contents	of the
       system clipboard.


	  strip_trailing_spaces	never

       Remove spaces at	the end	of lines when copying to clipboard. A value of
       smart will do it	when using normal selections, but not rectangle	selec-
       tions. always will always do it.


	  select_by_word_characters @-./_~?&=%+#

       Characters considered part of a word when double	clicking. In  addition
       to  these  characters  any  character that is marked as an alphanumeric
       character in the	unicode	database will be matched.


	  click_interval -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 no

       Set the active window to	the window under the  mouse  when  moving  the
       mouse around


	  pointer_shape_when_grabbed arrow

       The shape of the	mouse pointer when the program running in the terminal
       grabs the mouse.	Valid values are: arrow, beam and hand


	  default_pointer_shape	beam

       The default shape of the	mouse pointer. Valid values are:  arrow,  beam
       and hand


	  pointer_shape_when_dragging beam

       The default shape of the	mouse pointer when dragging across text. Valid
       values are: arrow, beam and hand

   Mouse actions
       Mouse buttons can be remapped to	perform	arbitrary actions. The	syntax
       for doing so is:

	  mouse_map button-name	event-type modes action

       Where button-name is one	of left, middle, right or b1 ... b8 with added
       keyboard	modifiers, for example:	ctrl+shift+left	refers to holding  the
       ctrl+shift  keys	 while clicking	with the left mouse button. The	number
       b1 ... b8 can be	used to	refer to upto eight buttons on a mouse.

       event-type is one press,	release, doublepress, triplepress,  click  and
       doubleclick.   modes indicates whether the action is performed when the
       mouse is	grabbed	by the program running in the terminal,	or not.	It can
       have  one  or  more or the values, grabbed,ungrabbed. grabbed refers to
       when the	program	running	in the terminal	has  requested	mouse  events.
       Note   that  the	 click	and  double  click  events  have  a  delay  of
       click_interval to disambiguate from double and triple presses.

       You can run kitty with the kitty	--debug-input command line  option  to
       see  mouse events. See the builtin actions below	to get a sense of what
       is possible.

       If you want to unmap an action map it to	no-op. For example, to disable
       opening of URLs with a plain click:

	  mouse_map left click ungrabbed no-op

	  Once	a  selection  is started, releasing the	button that started it
	  will automatically end it and	no release event will be dispatched.

       Click the link under the	mouse cursor when no selection is created

	  mouse_map left click ungrabbed mouse_click_url_or_select

       Click the link under the	mouse cursor when no selection is created even
       if grabbed

	  mouse_map shift+left click grabbed,ungrabbed mouse_click_url_or_select

       Click the link under the	mouse cursor

	  mouse_map ctrl+shift+left release grabbed,ungrabbed mouse_click_url

       Variant	with ctrl+shift	is present because the simple click based ver-
       sion has	an unavoidable delay of	click_interval,	to disambiguate	clicks
       from double clicks.

       Discard press event for link click

	  mouse_map ctrl+shift+left press grabbed discard_event

       Prevent	this  press  event  from  being	 sent  to the program that has
       grabbed the mouse, as the corresponding release event is	used to	open a

       Paste from the primary selection

	  mouse_map middle release ungrabbed paste_from_selection

       Start selecting text

	  mouse_map left press ungrabbed mouse_selection normal

       Start selecting text in a rectangle

	  mouse_map ctrl+alt+left press	ungrabbed mouse_selection rectangle

       Select a	word

	  mouse_map left doublepress ungrabbed mouse_selection word

       Select a	line

	  mouse_map left triplepress ungrabbed mouse_selection line

       Select the entire line

       Select line from	point

	  mouse_map ctrl+alt+left triplepress ungrabbed	mouse_selection	line_from_point

       Select from the clicked point to	the end	of the line

       Extend the current selection

	  mouse_map right press	ungrabbed mouse_selection extend

       Paste from the primary selection	even when grabbed

	  mouse_map shift+middle release ungrabbed,grabbed paste_selection

       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 shift+ctrl+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 the entire line

       Select line from	point even when	grabbed

	  mouse_map shift+ctrl+alt+left	triplepress ungrabbed,grabbed mouse_selection line_from_point

       Select from the clicked point to	the end	of the line

       Extend the current selection even when grabbed

	  mouse_map shift+right	press ungrabbed,grabbed	mouse_selection	extend


	  repaint_delay	10

       Delay  (in  milliseconds)  between  screen  updates. Decreasing it, in-
       creases frames-per-second (FPS) at the cost of more CPU usage. The  de-
       fault  value  yields  ~100  FPS	which is more than sufficient for most
       uses. Note that to actually achieve 100 FPS  you	 have  to  either  set
       sync_to_monitor	to no or use a monitor with a high refresh rate. Also,
       to minimize latency when	there is pending input to  be  processed,  re-
       paint_delay is ignored.


	  input_delay 3

       Delay  (in  milliseconds)  before input from the	program	running	in the
       terminal	is processed. Note that	decreasing it  will  increase  respon-
       siveness,  but  also increase CPU usage and might cause flicker in full
       screen programs that redraw the entire screen  on  each	loop,  because
       kitty is	so fast	that partial screen updates will be drawn.


	  sync_to_monitor yes

       Sync  screen  updates to	the refresh rate of the	monitor. This prevents
       tearing ( when  scrolling.
       However,	it limits the rendering	speed to the refresh rate of your mon-
       itor. With a very high speed mouse/high keyboard	repeat rate,  you  may
       notice some slight input	latency.  If so, set this to no.


	  enable_audio_bell yes

       Enable/disable  the audio bell. Useful in environments that require si-


	  visual_bell_duration 0.0

       Visual bell duration. Flash the screen when a bell occurs for the spec-
       ified number of seconds.	Set to zero to disable.


	  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 yes

       Show a bell symbol on the tab if	a bell occurs in one of	the windows in
       the tab and the window is not the currently focused window


	  command_on_bell none

       Program to run when a bell occurs.

       remember_window_size, initial_window_width, initial_window_height

	  remember_window_size	yes
	  initial_window_width	640
	  initial_window_height	400

       If enabled, the window size will	be remembered so that new instances of
       kitty will have the same	size as	the previous  instance.	 If  disabled,
       the   window  will  initially  have  size  configured  by  initial_win-
       dow_width/height, in pixels. You	 can  use  a  suffix  of  "c"  on  the
       width/height values to have them	interpreted as number of cells instead
       of pixels.


	  enabled_layouts *

       The enabled window layouts. A comma separated list of layout names. The
       special	value  all  means all layouts. The first listed	layout will be
       used as the startup layout. Default configuration is all	layouts	in al-
       phabetical order. For a list of available layouts, see the layouts.

       window_resize_step_cells, window_resize_step_lines

	  window_resize_step_cells 2
	  window_resize_step_lines 2

       The step	size (in units of cell width/cell height) to use when resizing
       windows.	 The cells value is used for horizontal	resizing and the lines
       value for vertical resizing.


	  window_border_width 0.5pt

       The  width of window borders. Can be either in pixels (px) or pts (pt).
       Values in pts will be rounded to	the nearest number of pixels based  on
       screen  resolution.   If	 not  specified	the unit is assumed to be pts.
       Note that borders are displayed only when more than one window is visi-
       ble. They are meant to separate multiple	windows.


	  draw_minimal_borders yes

       Draw  only the minimum borders needed. This means that only the minimum
       needed borders for inactive windows are drawn. That is only the borders
       that  separate the inactive window from a neighbor. Note	that setting a
       non-zero	window margin overrides	this and  causes  all  borders	to  be


	  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 -1

       The window margin (in pts) to use when only a single window is visible.
       Negative	 values	will cause the value of	window_margin_width to be used
       instead.	A single value sets all	four sides. Two	values set the	verti-
       cal  and	horizontal sides. Three	values set top,	horizontal and bottom.
       Four values set top, right, bottom and left.


	  window_padding_width 0

       The window padding (in pts) (blank area between the text	and the	window
       border).	 A single value	sets all four sides. Two values	set the	verti-
       cal and horizontal sides. Three values set top, horizontal and  bottom.
       Four values set top, right, bottom and left.


	  placement_strategy center

       When  the  window  size	is not an exact	multiple of the	cell size, the
       cell area of the	terminal window	will have some extra  padding  on  the
       sides.  You  can	 control how that padding is distributed with this op-
       tion. Using a value of center means the cell area will be  placed  cen-
       trally.	A value	of top-left means the padding will be on only the bot-
       tom and right edges.


	  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	#cccccc

       The color for the border	of inactive windows


	  bell_border_color #ff5a00

       The  color  for	the border of inactive windows in which	a bell has oc-


	  inactive_text_alpha 1.0

       Fade the	text in	inactive windows by the	specified amount (a number be-
       tween zero and one, with	zero being fully faded).


	  hide_window_decorations no

       Hide the	window decorations (title-bar and window borders) with yes. On
       macOS, titlebar-only can	be used	to only	 hide  the  titlebar.  Whether
       this  works  and	 exactly what effect it	has depends on the window man-
       ager/operating system. Note that	the effects of changing	 this  setting
       when reloading config are undefined.


	  resize_debounce_time 0.1

       The time	(in seconds) to	wait before redrawing the screen when a	resize
       event is	received. On platforms such as macOS, where the	operating sys-
       tem  sends  events corresponding	to the start and end of	a resize, this
       number is ignored.


	  resize_draw_strategy static

       Choose how kitty	draws a	window while a resize is in progress. A	 value
       of  static  means draw the current window contents, mostly unchanged. A
       value of	scale means draw the current window contents scaled.  A	 value
       of blank	means draw a blank window. A value of size means show the win-
       dow size	in cells.


	  resize_in_steps no

       Resize the OS window in steps as	large as the cells,  instead  of  with
       the  usual  pixel  accuracy.  Combined with an initial_window_width and
       initial_window_height in	number of cells, this option can  be  used  to
       keep the	margins	as small as possible when resizing the OS window. Note
       that this does not currently work on Wayland.


	  confirm_os_window_close 0

       Ask for confirmation when closing an OS window or a  tab	 that  has  at
       least this number of kitty windows in it. A value of zero disables con-
       firmation. This confirmation also applies to requests to	quit  the  en-
       tire application	(all OS	windows, via the quit action).


	  tab_bar_edge bottom

       Which edge to show the tab bar on, top or bottom


	  tab_bar_margin_width 0.0

       The margin to the left and right	of the tab bar (in pts)


	  tab_bar_margin_height	0.0 0.0

       The  margin  above  and below the tab bar (in pts). The first number is
       the margin between the edge of the OS Window and	the tab	 bar  and  the
       second number is	the margin between the tab bar and the contents	of the
       current tab.


	  tab_bar_style	fade

       The tab bar style, can be one of: fade, separator, powerline,  or  hid-
       den.  In	 the  fade  style,  each  tab's	edges fade into	the background
       color, in the separator style, tabs are	separated  by  a  configurable
       separator,  and	the powerline shows the	tabs as	a continuous line.  If
       you use the hidden style, you might want	to create a  mapping  for  the
       select_tab action which presents	you with a list	of tabs	and allows for
       easy switching to a tab.


	  tab_bar_min_tabs 2

       The minimum number of tabs that must exist before the tab bar is	shown


	  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 0.25	0.5 0.75 1

       Control how each	tab fades into the background when using fade for  the
       tab_bar_style. Each number is an	alpha (between zero and	one) that con-
       trols how much the corresponding	cell fades into	the  background,  with
       zero  being  no fade and	one being full fade. You can change the	number
       of cells	used by	adding/removing	entries	to this	list.


	  tab_separator	" a"

       The separator between tabs in the tab bar when using separator  as  the


	  tab_powerline_style angled

       The  powerline  separator  style	between	tabs in	the tab	bar when using
       powerline as the	tab_bar_style, can be  one  of:	 angled,  slanted,  or


	  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.


	  tab_title_template "{title}"

       A template to render the	tab title. The default just renders the	title.
       If  you wish to include the tab-index as	well, use something like: {in-
       dex}: {title}. Useful if	you have shortcuts mapped for goto_tab	N.  If
       you prefer to see the index as a	superscript, use {sup.index}. In addi-
       tion you	 can  use  {layout_name}  for  the  current  layout  name  and
       {num_windows}  for  the number of windows in the	tab. Note that format-
       ting is done by Python's	string formatting machinery, so	you  can  use,
       for instance, {layout_name[:2].upper()} to show only the	first two let-
       ters of the layout name,	upper-cased. If	you want to  style  the	 text,
       you can use styling directives, for example: {}red{
       fault}normal{}green  bg{}.  Similarly,   for
       bold	    and		italic:		{fmt.bold}bold{fmt.nobold}nor-


	  active_tab_title_template none

       Template	to use for  active  tabs,  if  not  specified  falls  back  to

       active_tab_foreground,	active_tab_background,	active_tab_font_style,
       inactive_tab_foreground,		inactive_tab_background,	 inac-

	  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 none

       Background  color for the tab bar. Defaults to using the	terminal back-
       ground color.

       foreground, background

	  foreground #dddddd
	  background #000000

       The foreground and background colors


	  background_opacity 1.0

       The opacity of the background. A	number between 0 and  1,  where	 1  is
       opaque and 0 is fully transparent.  This	will only work if supported by
       the OS (for instance, when using	a compositor under X11). Note that  it
       only  sets  the	background color's opacity in cells that have the same
       background color	as the default terminal	background. This  is  so  that
       things  like  the status	bar in vim, powerline prompts, etc. still look
       good.  But it means that	if you use a color  theme  with	 a  background
       color  in your editor, it will not be rendered as transparent.  Instead
       you should change the default background	color in your kitty config and
       not  use	 a background color in the editor color	scheme.	Or use the es-
       cape codes to set the terminals default colors in  a  shell  script  to
       launch  your  editor.   Be  aware that using a value less than 1.0 is a
       (possibly significant) performance hit.	If  you	 want  to  dynamically
       change  transparency  of	 windows set dynamic_background_opacity	to yes
       (this is	off by default as it has a performance	cost).	Changing  this
       setting	  when	  reloading    the    config   will   only   work   if
       dynamic_background_opacity was enabled in the original config.


	  background_image none

       Path to a background image. Must	be in PNG format.


	  background_image_layout tiled

       Whether to tile or scale	the background image.


	  background_image_linear no

       When background image is	scaled,	whether	linear interpolation should be


	  dynamic_background_opacity no

       Allow changing of the background_opacity	dynamically, using either key-
       board shortcuts (ctrl+shift+a_m and ctrl+shift+a_l) or the remote  con-
       trol  facility.	Changing  this	setting	by reloading the config	is not


	  background_tint 0.0

       How much	to tint	the background image by	the background color. The tint
       is  applied only	under the text area, not margin/borders. Makes it eas-
       ier to read the text. Tinting is	 done  using  the  current  background
       color for each window.  This setting applies only if background_opacity
       is set and transparent windows are  supported  or  background_image  is


	  dim_opacity 0.75

       How much	to dim text that has the DIM/FAINT attribute set. One means no
       dimming and zero	means fully dimmed (i.e. invisible).


	  selection_foreground #000000

       The foreground for text selected	with the mouse.	A value	of none	 means
       to leave	the color unchanged.


	  selection_background #fffacd

       The background for text selected	with the mouse.

   The color table
       The  256	 terminal  colors.  There are 8	basic colors, each color has a
       dull and	bright version,	for the	first 16 colors. You can set  the  re-
       maining 240 colors as color16 to	color255.

       color0, color8

	  color0 #000000
	  color8 #767676


       color1, color9

	  color1 #cc0403
	  color9 #f2201f


       color2, color10

	  color2  #19cb00
	  color10 #23fd00


       color3, color11

	  color3  #cecb00
	  color11 #fffd00


       color4, color12

	  color4  #0d73cc
	  color12 #1a8fff


       color5, color13

	  color5  #cb1ed1
	  color13 #fd28ff


       color6, color14

	  color6  #0dcdcd
	  color14 #14ffff


       color7, color15

	  color7  #dddddd
	  color15 #ffffff



	  mark1_foreground black

       Color for marks of type 1


	  mark1_background #98d3cb

       Color for marks of type 1 (light	steel blue)


	  mark2_foreground black

       Color for marks of type 2


	  mark2_background #f2dcd3

       Color for marks of type 1 (beige)


	  mark3_foreground black

       Color for marks of type 3


	  mark3_background #f274bc

       Color for marks of type 3 (violet)


	  shell	.

       The shell program to execute. The default value of . means to use what-
       ever shell is set as the	default	shell for the current user. Note  that
       on  macOS  if  you change this, you might need to add --login to	ensure
       that the	shell starts in	interactive mode  and  reads  its  startup  rc


	  editor .

       The console editor to use when editing the kitty	config file or similar
       tasks. A	value of . means to use	the environment	variables  VISUAL  and
       EDITOR in that order. Note that this environment	variable has to	be set
       not just	in your	shell startup scripts but system-wide, otherwise kitty
       will not	see it.


	  close_on_child_death no

       Close  the  window when the child process (shell) exits.	If no (the de-
       fault), the terminal will remain	open when the child exits as  long  as
       there  are still	processes outputting to	the terminal (for example dis-
       owned or	backgrounded processes). If yes, the window will close as soon
       as the child process exits.  Note that setting it to yes	means that any
       background processes still using	the terminal can fail silently because
       their stdout/stderr/stdin no longer work.


	  allow_remote_control no

       Allow  other  programs to control kitty.	If you turn this on other pro-
       grams can control all aspects of	kitty, including sending text to kitty
       windows,	 opening  new windows, closing windows,	reading	the content of
       windows,	etc.  Note that	this even works	over ssh connections. You  can
       chose  to  either allow any program running within kitty	to control it,
       with yes	or only	programs that connect to the socket specified with the
       kitty   --listen-on   command   line  option,  if  you  use  the	 value
       socket-only. The	latter is useful if you	want to	prevent	programs  run-
       ning  on	 a  remote  computer over ssh from controlling kitty. Changing
       this option by reloading	the config will	only affect newly created win-


	  listen_on none

       Tell  kitty  to listen to the specified unix/tcp	socket for remote con-
       trol connections. Note that this	will apply to all kitty	instances.  It
       can  be overridden by the kitty --listen-on command line	flag. This op-
       tion accepts only UNIX sockets, such  as	 unix:${TEMP}/mykitty  or  (on
       Linux)	unix:@mykitty.	 Environment   variables   are	 expanded.  If
       {kitty_pid} is present then it is replaced by  the  PID	of  the	 kitty
       process,	 otherwise  the	 PID  of  the kitty process is appended	to the
       value, with a hyphen. This  option  is  ignored	unless	you  also  set
       allow_remote_control  to	 enable	remote control.	See the	help for kitty
       --listen-on for more details. Changing this  option  by	reloading  the
       config is not supported.



       Specify	environment variables to set in	all child processes. Note that
       environment variables are expanded recursively, so if you use:

	  env MYVAR1=a
	  env MYVAR2=${MYVAR1}/${HOME}/b

       The value of MYVAR2 will	be a/<path to home directory>/b.


	  update_check_interval	24

       Periodically check if an	update to kitty	is available. If an update  is
       found a system notification is displayed	informing you of the available
       update. The default is to check every 24	hrs, set to zero  to  disable.
       Changing	this option by reloading the config is not supported.


	  startup_session none

       Path  to	a session file to use for all kitty instances. Can be overrid-
       den by using the	kitty --session	command	line option for	individual in-
       stances.	See sessions in	the kitty documentation	for details. Note that
       relative	paths are interpreted with respect to the kitty	config	direc-
       tory.   Environment  variables  in the path are expanded. Changing this
       option by reloading the config is not supported.


	  clipboard_control write-clipboard write-primary

       Allow programs running in kitty to read and write from  the  clipboard.
       You  can	control	exactly	which actions are allowed. The set of possible
       actions is: write-clipboard read-clipboard write-primary	 read-primary.
       You  can	additionally specify no-append to disable kitty's protocol ex-
       tension for clipboard concatenation. The	default	is to allow writing to
       the  clipboard  and  primary selection with concatenation enabled. Note
       that enabling the read functionality is a security  risk	 as  it	 means
       that  any program, even one running on a	remote server via SSH can read
       your clipboard.


	  allow_hyperlinks yes

       Process hyperlink (OSC 8) escape	sequences. If disabled	OSC  8	escape
       sequences  are ignored. Otherwise they become clickable links, that you
       can click by holding down ctrl+shift and	clicking with the  mouse.  The
       special value of	ask means that kitty will ask before opening the link.


	  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, de-
       pending on what programs	you run, and how different  the	 terminal  you
       are  changing  it to is,	various	things from key-presses, to colors, to
       various advanced	features may not work. Changing	this option by reload-
       ing the config will only	affect newly created windows.


	  wayland_titlebar_color system

       Change the color	of the kitty window's titlebar on Wayland systems with
       client side window decorations such as GNOME. A value of	 system	 means
       to use the default system color,	a value	of background means to use the
       background color	of the currently active	window and finally you can use
       an arbitrary color, such	as #12af59 or red.


	  macos_titlebar_color system

       Change  the  color  of the kitty	window's titlebar on macOS. A value of
       system means to use the default system color,  a	 value	of  background
       means  to  use  the background color of the currently active window and
       finally you can use an arbitrary	color, such as #12af59 or  red.	 WARN-
       ING: This option	works by using a hack, as there	is no proper Cocoa API
       for it. It sets the background color of the entire window and makes the
       titlebar	   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 no

       Use  the	 option	key as an alt key. With	this set to no,	kitty will use
       the macOS native	Option+Key = unicode  character	 behavior.  This  will
       break any Alt+key keyboard shortcuts in your terminal programs, but you
       can use the macOS unicode input technique.  You	can  use  the  values:
       left, right, or both to use only	the left, right	or both	Option keys as
       Alt, instead. Changing this setting by reloading	the config is not sup-


	  macos_hide_from_tasks	no

       Hide  the  kitty	 window	 from running tasks (^a+Tab) on macOS. Changing
       this setting by reloading the config is not supported.


	  macos_quit_when_last_window_closed no

       Have kitty quit when all	the top-level windows are closed. By  default,
       kitty  will stay	running, even with no open windows, as is the expected
       behavior	on macOS.


	  macos_window_resizable yes

       Disable this if you want	kitty top-level	(OS) windows to	not be	resiz-
       able  on	macOS. Changing	this setting by	reloading the config will only
       affect newly created windows.


	  macos_thicken_font 0

       Draw an extra border around the font with the given width, to  increase
       legibility  at  small font sizes. For example, a	value of 0.75 will re-
       sult in rendering that looks similar to sub-pixel antialiasing at  com-
       mon font	sizes.


	  macos_traditional_fullscreen no

       Use  the	 traditional  full-screen transition, that is faster, but less


	  macos_show_window_title_in all

       Show or hide the	window title in	the macOS window or menu-bar. A	 value
       of window will show the title of	the currently active window at the top
       of the macOS window. A value of menubar will show the title of the cur-
       rently  active  window  in  the macOS menu-bar, making use of otherwise
       wasted space. all will show the title everywhere	and none hides the ti-
       tle in the window and the menu-bar.


	  macos_custom_beam_cursor no

       Enable/disable  custom  mouse cursor for	macOS that is easier to	see on
       both light and dark backgrounds.	WARNING: this might  make  your	 mouse
       cursor invisible	on dual	GPU machines. Changing this setting by reload-
       ing the config is not supported.


	  linux_display_server auto

       Choose between Wayland and X11 backends.	 By  default,  an  appropriate
       backend	based  on  the system state is chosen automatically. Set it to
       x11 or wayland to force the choice. Changing this setting by  reloading
       the config is not supported.

       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 func-
       tional.	For a list of modifier names, see: GLFW	mods

       On Linux	you can	also use XKB key names to bind keys that are not  sup-
       ported  by  GLFW. See XKB keys for a list of key	names. The name	to use
       is the part after the XKB_KEY_ prefix. Note that	you can	 only  use  an
       XKB key name for	keys that are not known	as GLFW	keys.

       Finally,	 you  can use raw system key codes to map keys,	again only for
       keys that are not known as GLFW keys. To	see the	system key code	for  a
       key,  start  kitty with the kitty --debug-input option. Then kitty will
       output some debug text for every	key event. In that text	look  for  na-
       tive_code  the  value of	that becomes the key name in the shortcut. For

	  on_key_input:	glfw key: 65 native_code: 0x61 action: PRESS mods: 0x0 text: 'a'

       Here, the key name for the A key	is 0x61	and you	can use	it with:

	  map ctrl+0x61	something

       to map ctrl+a to	something.

       You can use the special action no_op to unmap a keyboard	shortcut  that
       is assigned in the default configuration:

	  map kitty_mod+space no_op

       You  can	combine	multiple actions to be triggered by a single shortcut,
       using the syntax	below:

	  map key combine <separator> action1 <separator> action2 <separator> action3 ...

       For example:

	  map kitty_mod+e combine : new_window : next_layout

       this will create	a new window and switch	to the next available layout

       You can use multi-key shortcuts using the syntax	shown below:

	  map key1>key2>key3 action

       For example:

	  map ctrl+f>2 set_font_size 20


	  kitty_mod ctrl+shift

       The value of kitty_mod is used as the modifier for all  default	short-
       cuts,  you can change it	in your	kitty.conf to change the modifiers for
       all the default shortcuts.


	  clear_all_shortcuts no

       You can have kitty remove all  shortcut	definition  seen  up  to  this
       point. Useful, for instance, to remove the default shortcuts.


	  kitten_alias hints hints --hints-offset=0

       You can create aliases for kitten names,	this allows overriding the de-
       faults for kitten options and can also be used to shorten repeated map-
       pings of	the same kitten	with a specific	group of options. For example,
       the above alias changes	the  default  value  of	 kitty	+kitten	 hints
       --hints-offset to zero for all mappings,	including the builtin ones.

       Copy to clipboard

	  map ctrl+shift+c copy_to_clipboard

       There  is also a	copy_or_interrupt action that can be optionally	mapped
       to Ctrl+c. It will copy only if there is	a selection and	send an	inter-
       rupt  otherwise.	 Similarly,  copy_and_clear_or_interrupt will copy and
       clear the selection or send an interrupt	if there is no selection.

       Paste from clipboard

	  map ctrl+shift+v paste_from_clipboard

       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
       using  pass_selection_to_program. By default, the system's open program
       is used,	but you	can specify your own, the selection will be passed  as
       a command line argument to the program, for example:

	  map kitty_mod+o pass_selection_to_program firefox

       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

       Scroll line up

	  map ctrl+shift+up scroll_line_up
	  map ctrl+shift+k scroll_line_up
	  map alt+cmd+page_up scroll_line_up dh
	  map cmd+up scroll_line_up dh

       Scroll line down

	  map ctrl+shift+down scroll_line_down
	  map ctrl+shift+j scroll_line_down
	  map alt+cmd+page_down	scroll_line_down dh
	  map cmd+down scroll_line_down	dh

       Scroll page up

	  map ctrl+shift+page_up scroll_page_up
	  map cmd+page_up scroll_page_up dh

       Scroll page down

	  map ctrl+shift+page_down scroll_page_down
	  map cmd+page_down scroll_page_down dh

       Scroll to top

	  map ctrl+shift+home scroll_home
	  map cmd+home scroll_home dh

       Scroll to bottom

	  map ctrl+shift+end scroll_end
	  map cmd+end scroll_end dh

       Browse scrollback buffer	in less

	  map ctrl+shift+h show_scrollback

       You can pipe the	contents of the	current	screen	+  history  buffer  as
       STDIN  to  an arbitrary program using the launch	function. For example,
       the following opens the scrollback buffer in less in an overlay window:

	  map f1 launch	--stdin-source=@screen_scrollback --stdin-add-formatting --type=overlay	less +G	-R

       For more	details	on piping screen and buffer contents to	external  pro-
       grams, see launch.

   Window management
       New window

	  map ctrl+shift+enter new_window
	  map cmd+enter	new_window dh

       You can open a new 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	 by prefixing the command line with @.
       Any programs running in that window will	be allowed to  control	kitty.
       For example:

	  map ctrl+enter launch	--allow-remote-control some_program

       You can open a new window next to the currently active window or	as the
       first window, with:

	  map ctrl+n launch --location=neighbor	some_program
	  map ctrl+f launch --location=first some_program

       For more	details, see launch.

       New OS window

	  map ctrl+shift+n new_os_window
	  map cmd+n new_os_window dh

       Works like new_window above, except that	it opens a top level OS	 kitty
       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 dh

       Next window

	  map ctrl+shift+] next_window

       Previous	window

	  map ctrl+shift+[ previous_window

       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 dh

   Tab management
       Next tab

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

       Previous	tab

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

       New tab

	  map ctrl+shift+t new_tab
	  map cmd+t new_tab dh

       Close tab

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

       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	dh

       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	use 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

   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 dh
	  map cmd+equal	change_font_size all +2.0 dh
	  map cmd+shift+equal change_font_size all +2.0	dh

       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 dh
	  map cmd+shift+minus change_font_size all -2.0	dh

       Reset font size

	  map ctrl+shift+backspace change_font_size all	0
	  map cmd+0 change_font_size all 0 dh

       To setup	shortcuts for specific font sizes:

	  map kitty_mod+f6 change_font_size all	10.0

       To setup	shortcuts to change only the current OS	window's font size:

	  map kitty_mod+f6 change_font_size current 10.0

   Select and act on visible text
       Use the hints kitten to select text and either pass it to  an  external
       program or insert it into the terminal or copy it to the	clipboard.

       Open URL

	  map ctrl+shift+e kitten hints

       Open  a	currently  visible URL using the keyboard. The program used to
       open the	URL is specified in open_url_with.

       Insert selected path

	  map ctrl+shift+p>f kitten hints --type path --program	-

       Select a	path/filename and insert it into the terminal. Useful, for in-
       stance  to  run	git  commands on a filename output from	a previous git

       Open selected path

	  map ctrl+shift+p>shift+f kitten hints	--type path

       Select a	path/filename and open it with the default open	program.

       Insert selected line

	  map ctrl+shift+p>l kitten hints --type line --program	-

       Select a	line of	text and insert	it into	the terminal. Use for the out-
       put of things like: ls -1

       Insert selected word

	  map ctrl+shift+p>w kitten hints --type word --program	-

       Select words and	insert into terminal.

       Insert selected hash

	  map ctrl+shift+p>h kitten hints --type hash --program	-

       Select  something  that looks like a hash and insert it into the	termi-
       nal. Useful with	git, which uses	sha1 hashes to identify	commits

       Open the	selected file at the selected line

	  map ctrl+shift+p>n kitten hints --type linenum

       Select something	that looks like	filename:linenum and open it in	vim at
       the specified line number.

       Open the	selected hyperlink

	  map ctrl+shift+p>y kitten hints --type hyperlink

       Select a	hyperlink (i.e.	a URL that has been marked as such by the ter-
       minal program, for example, by ls --hyperlink=auto).

       The hints kitten	has many more modes of operation that you can  map  to
       different shortcuts. For	a full description see kittens/hints.

       Toggle fullscreen

	  map ctrl+shift+f11 toggle_fullscreen

       Toggle maximized

	  map ctrl+shift+f10 toggle_maximized

       Unicode input

	  map ctrl+shift+u kitten unicode_input
	  map cmd+ctrl+space kitten unicode_input dh

       Edit config file

	  map ctrl+shift+f2 edit_config_file
	  map cmd+, edit_config_file dh

       Open the	kitty command shell

	  map ctrl+shift+escape	kitty_shell window

       Open  the  kitty	shell in a new window/tab/overlay/os_window to control
       kitty using commands.

       Increase	background opacity

	  map ctrl+shift+a>m set_background_opacity +0.1

       Decrease	background opacity

	  map ctrl+shift+a>l set_background_opacity -0.1

       Make background fully opaque

	  map ctrl+shift+a>1 set_background_opacity 1

       Reset background	opacity

	  map ctrl+shift+a>d set_background_opacity default

       Reset the terminal

	  map ctrl+shift+delete	clear_terminal reset active
	  map cmd+option+r clear_terminal reset	active dh

       You can create shortcuts	to clear/reset the terminal. For example:

	  # Reset the terminal
	  map kitty_mod+f9 clear_terminal reset	active
	  # Clear the terminal screen by erasing all contents
	  map kitty_mod+f10 clear_terminal clear active
	  # Clear the terminal scrollback by erasing it
	  map kitty_mod+f11 clear_terminal scrollback active
	  # Scroll the contents	of the screen into the scrollback
	  map kitty_mod+f12 clear_terminal scroll active

       If you want to operate on all windows instead of	just the current  one,
       use all instead of active.

       It  is  also possible to	remap Ctrl+L to	both scroll the	current	screen
       contents	into the scrollback buffer and clear the  screen,  instead  of
       just  clearing  the  screen,  for example, for ZSH add the following to

	  scroll-and-clear-screen() {
	      printf '\n%.0s' {1..$LINES}
	      zle clear-screen
	  zle -N scroll-and-clear-screen
	  bindkey '^l' scroll-and-clear-screen

       Reload kitty.conf

	  map ctrl+shift+f5 load_config_file
	  map cmd+control+, load_config_file dh

       Reload kitty.conf, applying any changes since  the  last	 time  it  was
       loaded.	 Note that a handful of	settings cannot	be dynamically changed
       and require a full restart of kitty.  You can also map a	keybinding  to
       load a different	config file, for example:

	  map f5 load_config /path/to/alternative/kitty.conf

       Note  that  all	setting	from the original kitty.conf are discarded, in
       other words the new conf	settings replace the old ones.

       Debug kitty configuration

	  map ctrl+shift+f6 debug_config
	  map cmd+option+, debug_config	dh

       Show details about exactly what configuration kitty is running with and
       its host	environment. Useful for	debugging issues.

       Send arbitrary text on key presses

       You can tell kitty to send arbitrary (UTF-8) encoded text to the	client
       program when pressing specified shortcut	keys. For example:

	  map ctrl+alt+a send_text all Special text

       This will send "Special text" when you press the	ctrl+alt+a key	combi-
       nation.	 The text to be	sent is	a python string	literal	so you can use
       escapes like \x1b to send control codes or \u21fb to send unicode char-
       acters  (or you can just	input the unicode characters directly as UTF-8
       text). The first	argument to send_text is the keyboard modes  in	 which
       to activate the shortcut. The possible values are normal	or application
       or kitty	or a comma separated combination of them.  The special keyword
       all means all modes. The	modes normal and application refer to the DEC-
       CKM cursor key mode for terminals, and  kitty  refers  to  the  special
       kitty extended keyboard protocol.

       Another	example,  that outputs a word and then moves the cursor	to the
       start of	the line (same as pressing the Home key):

	  map ctrl+alt+a send_text normal Word\x1b[H
	  map ctrl+alt+a send_text application Word\x1bOH

       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.
