# vim:fileencoding=utf-8:foldmethod=marker #: Fonts {{{ #: kitty has very powerful font management. You can configure #: individual font faces and even specify special fonts for particular #: characters. font_family Fira Code Medium Nerd Font Complete bold_font Fira Code Bold Nerd Font Complete # 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. 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 10.0 #: 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 #: 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. # adjust_line_height 0 # adjust_column_width 0 #: Change the size of each character cell kitty renders. You can use #: either 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 interpreted 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+. You #: can specify multiple code points, separated by commas and ranges #: separated by hyphens. symbol_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 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 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 Ø. 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 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, these are read from the FontConfig database first and #: then this, setting is applied, so they can be configured in a #: single, central place. #: To get the PostScript name for a font, use kitty + list-fonts #: --psnames: #: .. code-block:: sh #: $ 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 #: 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. #: }}} #: Cursor customization {{{ # 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 {{{ # 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 scrollback buffer in a separate window. The current #: implementation stores the data in UTF-8, so approximatively 10000 #: lines per megabyte at 100 chars per line, for pure ASCII text, #: unformatted text. A value of zero or less 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 window. # 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 #: Wayland. Use negative numbers to change scroll direction. #: }}} #: Mouse {{{ # 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 #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 #: underline and the mouse cursor becomes a hand over them. Even if #: this option is disabled, URLs are still clickable. # url_excluded_characters #: Additional characters to be disallowed from URLs, when detecting #: URLs under the mouse cursor. By default, all characters legal in #: URLs are allowed. # copy_on_select no #: Copy to clipboard or a private buffer on select. With this set to #: clipboard, simply selecting text with the mouse will cause the text #: to be copied to clipboard. Useful on platforms such as macOS that #: do not have the concept of primary selections. You can instead #: specify a name such as a1 to copy to a private kitty buffer #: instead. Map a shortcut with the paste_from_buffer action to paste #: from this private buffer. For example:: #: map cmd+shift+v paste_from_buffer a1 #: Note that copying to the clipboard is a security risk, as all #: programs, including websites open in your browser can read the #: contents of the system clipboard. # strip_trailing_spaces never #: Remove spaces at the end of lines when copying to clipboard. A #: value of smart will do it when using normal selections, but not #: rectangle selections. always will always do it. # select_by_word_characters @-./_~?&=%+# #: 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: #: .. code-block:: none #: 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 #: .. 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 no #: You can have kitty remove all mouse actions seen up to this point. #: Useful, for instance, to remove the default mouse actions. # mouse_map left click ungrabbed mouse_click_url_or_select # mouse_map shift+left click grabbed,ungrabbed mouse_click_url_or_select # mouse_map ctrl+shift+left release grabbed,ungrabbed mouse_click_url #: Variant with ctrl+shift is present because the simple click based #: version has an unavoidable delay of click_interval, to disambiguate #: clicks from double clicks. # 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. # mouse_map middle release ungrabbed paste_from_selection # mouse_map left press ungrabbed mouse_selection normal # mouse_map ctrl+alt+left press ungrabbed mouse_selection rectangle # mouse_map left doublepress ungrabbed mouse_selection word # mouse_map left triplepress ungrabbed mouse_selection line #: Select the entire line # mouse_map ctrl+alt+left triplepress ungrabbed mouse_selection line_from_point #: Select from the clicked point to the end of the line # 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. # mouse_map shift+middle release ungrabbed,grabbed paste_selection # mouse_map shift+left press ungrabbed,grabbed mouse_selection normal # mouse_map shift+ctrl+alt+left press ungrabbed,grabbed mouse_selection rectangle # mouse_map shift+left doublepress ungrabbed,grabbed mouse_selection word # mouse_map shift+left triplepress ungrabbed,grabbed mouse_selection line #: Select the entire line # 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 # mouse_map shift+right press ungrabbed,grabbed mouse_selection extend #: }}} #: }}} #: Performance tuning {{{ # repaint_delay 10 #: Delay (in milliseconds) between screen updates. Decreasing it, #: increases frames-per-second (FPS) at the cost of more CPU usage. #: The default value yields ~100 FPS which is more than sufficient for #: most uses. Note that to actually achieve 100 FPS you have to either #: set sync_to_monitor to no or use a monitor with a high refresh #: rate. Also, to minimize latency when there is pending input to be #: processed, repaint_delay is ignored. # input_delay 3 #: Delay (in milliseconds) before input from the program running in #: the terminal is processed. 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 yes #: Sync screen updates to the refresh rate of the monitor. This #: prevents tearing (https://en.wikipedia.org/wiki/Screen_tearing) #: when scrolling. However, it limits the rendering speed to the #: refresh rate of your monitor. With a very high speed mouse/high #: keyboard repeat rate, you may notice some slight input latency. If #: so, set this to no. #: }}} #: Terminal bell {{{ # enable_audio_bell yes #: Enable/disable the audio bell. Useful in environments that require #: silence. # visual_bell_duration 0.0 #: Visual bell duration. Flash the screen when a bell occurs for the #: specified number of seconds. Set to zero to disable. # window_alert_on_bell 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. The environment variable #: KITTY_CHILD_CMDLINE can be used to get the program running in the #: window in which the bell occurred. #: }}} #: Window layout {{{ # 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_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 * #: 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 https://sw.kovidgoyal.net/kitty/overview/#layouts. # 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 visible. 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 drawn. # 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 vertical 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 vertical 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 option. Using a value of center means the cell area will be #: placed centrally. A value of top-left means the padding will be on #: only the bottom and right edges. # active_border_color #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 #: occurred # 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 no #: Hide the window decorations (title-bar and window borders) with #: yes. On macOS, titlebar-only can be used to only hide the titlebar. #: Whether this works and exactly what effect it has depends on the #: window manager/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 system 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 window 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 #: confirmation. This confirmation also applies to requests to quit #: the entire application (all OS windows, via the quit action). #: }}} #: Tab bar {{{ # 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 #: Each tab's edges fade into the background color (see tab_fade) #: slant #: Tabs look like the tabs in a physical file #: separator #: Tabs are separated by a configurable separator (see tab_separator) #: powerline #: Tabs are shown as a continuous line with "fancy" separators (see tab_powerline_style) #: hidden #: The tab bar is hidden. If you use this, you might want to create a mapping #: for the https://sw.kovidgoyal.net/kitty/actions/#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 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 " ┇" #: The separator between tabs in the tab bar when using separator as #: the tab_bar_style. # tab_powerline_style angled #: The powerline separator style between tabs in the tab bar when #: using powerline as the tab_bar_style, can be one of: angled, #: slanted, or round. # tab_activity_symbol 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. # tab_title_template "{title}" #: A template to render the tab title. The default just renders the #: title. If you wish to include the tab-index as well, use something #: like: {index}: {title}. Useful if you have shortcuts mapped for #: goto_tab N. If you prefer to see the index as a superscript, use #: {sup.index}. In addition you can use {layout_name} for the current #: layout name, {num_windows} for the number of windows in the tab and #: {num_window_groups} for the number of window groups (not counting #: overlay windows) in the tab. Note that formatting is done by #: Python's string formatting machinery, so you can use, for instance, #: {layout_name[:2].upper()} to show only the first two letters of the #: layout name, upper-cased. If you want to style the text, you can #: use styling directives, for example: #: {fmt.fg.red}red{fmt.fg.default}normal{fmt.bg._00FF00}green #: bg{fmt.bg.normal}. Similarly, for bold and italic: #: {fmt.bold}bold{fmt.nobold}normal{fmt.italic}italic{fmt.noitalic}. # active_tab_title_template none #: Template to use for active tabs, if not specified falls back to #: tab_title_template. # 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 #: background color. #: }}} #: Color scheme {{{ # 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 escape #: codes to set the terminals default colors in a shell script to #: launch your editor. Be aware that using a value less than 1.0 is a #: (possibly significant) performance hit. If you want to dynamically #: change transparency of windows set dynamic_background_opacity to #: yes (this is off by default as it has a performance cost). Changing #: this setting when reloading the config will only work if #: dynamic_background_opacity was enabled in the original config. # background_image 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 used. # dynamic_background_opacity no #: Allow changing of the background_opacity dynamically, using either #: keyboard shortcuts (increase_background_opacity and #: decrease_background_opacity) or the remote control facility. #: Changing this setting by reloading the config is not supported. # background_tint 0.0 #: How much to tint the background image by the background color. The #: tint is applied only under the text area, not margin/borders. Makes #: it easier to read the text. Tinting is done using the current #: background color for each window. This setting applies only if #: background_opacity is set and transparent windows are supported or #: background_image is set. # dim_opacity 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 #: remaining 240 colors as color16 to color255. # color0 #000000 # color8 #767676 #: black # color1 #cc0403 # color9 #f2201f #: red # color2 #19cb00 # color10 #23fd00 #: green # color3 #cecb00 # color11 #fffd00 #: yellow # color4 #0d73cc # color12 #1a8fff #: blue # color5 #cb1ed1 # color13 #fd28ff #: magenta # color6 #0dcdcd # color14 #14ffff #: cyan # color7 #dddddd # color15 #ffffff #: white # 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) #: }}} #: }}} #: Advanced {{{ # 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. # editor . #: The terminal 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 (``$SHELL -l -i -c env``) to see if your #: shell config files set VISUAL or EDITOR. If that doesn't work, #: kitty will cycle through various known editors (``vim``, ``emacs``, #: etc) and take the first one that exists on your system. # close_on_child_death no #: Close the window when the child process (shell) exits. If no (the #: default), the terminal will remain open when the child exits as #: long as there are still processes outputting to the terminal (for #: example disowned or backgrounded processes). If yes, the window #: will close as soon as the child process exits. Note that setting it #: to yes means that any background processes still using the terminal #: can fail silently because their stdout/stderr/stdin no longer work. # allow_remote_control no #: Allow other programs to control kitty. If you turn this on other #: programs can control all aspects of kitty, including sending text #: to kitty windows, opening new windows, closing windows, reading the #: content of windows, etc. Note that this even works over ssh #: connections. You can chose to either allow any program running #: within kitty to control it, with yes or only programs that connect #: to the socket specified with the kitty --listen-on command line #: option, if you use the value socket-only. The latter is useful if #: you want to prevent programs running on a remote computer over ssh #: from controlling kitty. Reloading the config will not affect this #: setting. # listen_on none #: Tell kitty to listen to the specified unix/tcp socket for remote #: control connections. Note that this will apply to all kitty #: instances. It can be overridden by the kitty --listen-on command #: line flag. This option accepts only UNIX sockets, such as #: unix:${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. # env #: 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//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 #: overridden by using the kitty --session command line option for #: individual instances. See #: https://sw.kovidgoyal.net/kitty/overview/#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 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. The default is to allow writing to the #: clipboard and primary selection. 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. See #: also clipboard_max_size. # clipboard_max_size 64 #: The maximum size (in MB) of data from programs running in kitty #: that will be stored for writing to the system clipboard. See also #: clipboard_control. A value of zero means no size limit is applied. # 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, 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. #: }}} #: OS specific tweaks {{{ # 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. WARNING: This option works by using a hack, as #: there is no proper Cocoa API for it. It sets the background color #: of the entire window and makes the titlebar 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 supported. # macos_hide_from_tasks no #: Hide the kitty window from running tasks (⌘+Tab) on macOS. Changing #: this setting by reloading the config is not supported. # macos_quit_when_last_window_closed 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 #: resizable 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 result in rendering that looks similar to sub-pixel #: antialiasing at common font sizes. # macos_traditional_fullscreen no #: Use the traditional full-screen transition, that is faster, but #: less pretty. # 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 currently active window in the macOS menu-bar, making #: use of otherwise wasted space. all will show the title everywhere #: and none hides the title 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 reloading 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. #: }}} #: 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 https://sw.kovidgoyal.net/kitty/keyboard- #: protocol/#functional-key-definitions. For a list of modifier names, #: see: GLFW mods #: On Linux you can also use XKB key names to bind keys that are not #: supported by GLFW. See XKB keys #: for a list of key names. The name to use is the part #: after the XKB_KEY_ prefix. 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 ``native_code`` the value of that becomes the key #: name in the shortcut. For example: #: .. code-block:: none #: 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 action1 action2 action3 ... #: For example:: #: map kitty_mod+e combine : new_window : next_layout #: this will create a new window and switch to the next available #: layout #: 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 #: The full list of actions that can be mapped to key presses is #: available here . # kitty_mod ctrl+shift #: The value of kitty_mod is used as the modifier for all default #: shortcuts, 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 #: defaults for kitten options and can also be used to shorten #: repeated mappings of the same kitten with a specific group of #: options. For example, the above alias changes the default value of #: kitty +kitten hints --hints-offset to zero for all mappings, #: including the builtin ones. #: Clipboard {{{ # map kitty_mod+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. # map kitty_mod+v paste_from_clipboard # map kitty_mod+s paste_from_selection # map kitty_mod+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 #: }}} #: Scrolling {{{ # map kitty_mod+up scroll_line_up # map kitty_mod+down scroll_line_down # map kitty_mod+page_up scroll_page_up # map kitty_mod+page_down scroll_page_down # map kitty_mod+home scroll_home # map kitty_mod+end scroll_end # map kitty_mod+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 #: programs, see launch. #: }}} #: Window management {{{ # map kitty_mod+enter new_window #: 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. # map kitty_mod+n new_os_window #: Works like new_window above, except that it opens a top level OS #: kitty window.

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 {{{ # map kitty_mod+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 function 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. # map kitty_mod+equal change_font_size all +2.0 # map kitty_mod+minus change_font_size all -2.0 # map kitty_mod+backspace change_font_size all 0 #: 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. # map kitty_mod+e open_url_with_hints #: Open a currently visible URL using the keyboard. The program used #: to open the URL is specified in open_url_with. # map kitty_mod+p>f kitten hints --type path --program - #: Select a path/filename and insert it into the terminal. Useful, for #: instance to run git commands on a filename output from a previous #: git command. # map kitty_mod+p>shift+f kitten hints --type path #: Select a path/filename and open it with the default open program. # map kitty_mod+p>l kitten hints --type line --program - #: Select a line of text and insert it into the terminal. Use for the #: output of things like: ls -1 # map kitty_mod+p>w kitten hints --type word --program - #: Select words and insert into terminal. # map kitty_mod+p>h kitten hints --type hash --program - #: Select something that looks like a hash and insert it into the #: terminal.

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. # map kitty_mod+f6 debug_config #: Show details about exactly what configuration kitty is running with #: and its host environment. Useful for debugging issues. #: 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 is a python string literal so you #: can use escapes like \x1b to send control codes or \u21fb to send #: unicode characters (or you can just input the unicode characters #: directly as UTF-8 text). The first argument to send_text is the #: keyboard modes in which to activate the shortcut. The possible #: values are normal or application or kitty or a comma separated #: combination of them. The special keyword all means all modes. The #: modes normal and application refer to the DECCKM 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 #: }}} #: }}}
