# 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 monospace # bold_font auto # italic_font auto # bold_italic_font auto #: You can specify different fonts for the bold/italic/bold-italic #: variants. To get a full list of supported fonts use the `kitty #: +list-fonts` command. By default they are derived automatically, by #: the OSes font system. When bold_font or bold_italic_font is set to #: auto on macOS, the priority of bold fonts is semi-bold, bold, #: heavy. Setting them manually is useful for font families that have #: many weight variants like Book, Medium, Thick, etc. For example:: #: font_family Operator Mono Book #: bold_font Operator Mono Medium #: italic_font Operator Mono Book Italic #: bold_italic_font Operator Mono Medium Italic font_size 15.0 #: 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. # symbol_map #: E.g. 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. This option can be specified multiple times. #: The syntax is:: #: symbol_map codepoints Font Family Name # narrow_symbols #: E.g. narrow_symbols U+E0A0-U+E0A3,U+E0C0-U+E0C7 1 #: Usually, for Private Use Unicode characters and some symbol/dingbat #: characters, if the character is followed by one or more spaces, #: kitty will use those extra cells to render the character larger, if #: the character in the font has a wide aspect ratio. Using this #: option you can force kitty to restrict the specified code points to #: render in the specified number of cells (defaulting to one cell). #: This option can be specified multiple times. The syntax is:: #: narrow_symbols codepoints [optionally the number of cells] # disable_ligatures never #: Choose how you want to handle multi-character ligatures. The #: default is to always render them. You can tell kitty to not render #: them when the cursor is over them by using cursor to make editing #: easier, or have kitty never render them at all by using always, if #: you don't like them. The ligature strategy can be set per-window #: either using the kitty remote control facility or by defining #: shortcuts for it in kitty.conf, for example:: #: map alt+1 disable_ligatures_in active always #: map alt+2 disable_ligatures_in all never #: map alt+3 disable_ligatures_in tab cursor #: Note that this refers to programming ligatures, typically #: implemented using the calt OpenType feature. For disabling general #: ligatures, use the font_features option. # font_features #: E.g. font_features none #: Choose exactly which OpenType features to enable or disable. This #: is useful as some fonts might have features worthwhile in a #: terminal. For example, Fira Code includes a discretionary feature, #: zero, which in that font changes the appearance of the zero (0), to #: make it more easily distinguishable from Ø. Fira Code also includes #: other discretionary features known as Stylistic Sets which have the #: tags ss01 through ss20. #: For the exact syntax to use for individual features, see the #: HarfBuzz documentation . #: Note that this code is indexed by PostScript name, and not the font #: family. This allows you to define very precise feature settings; #: e.g. you can disable a feature in the italic font but not in the #: regular font. #: On Linux, font features are first read from the FontConfig database #: and then this option is applied, so they can be configured in a #: single, central place. #: To get the PostScript name for a font, use `kitty +list-fonts #: --psnames`: #: .. 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 in the bold font:: #: font_features FiraCode-Bold +zero #: Disable the normal ligatures, but keep the calt feature which (in #: this font) breaks up monotony:: #: font_features TT2020StyleB-Regular -liga +calt #: In conjunction with force_ltr, you may want to disable Arabic #: shaping entirely, and only look at their isolated forms if they #: show up in a document. You can do this with e.g.:: #: font_features UnifontMedium +isol -medi -fina -init # modify_font #: Modify font characteristics such as the position or thickness of #: the underline and strikethrough. The modifications can have the #: suffix px for pixels or % for percentage of original value. No #: suffix means use pts. For example:: #: modify_font underline_position -2 #: modify_font underline_thickness 150% #: modify_font strikethrough_position 2px #: Additionally, you can modify the size of the cell in which each #: font glyph is rendered and the baseline at which the glyph is #: placed in the cell. For example:: #: modify_font cell_width 80% #: modify_font cell_height -2px #: modify_font baseline 3 #: Note that modifying the baseline will automatically adjust the #: underline and strikethrough positions by the same amount. #: Increasing the baseline raises glyphs inside the cell and #: decreasing it lowers them. Decreasing the cell size might cause #: rendering artifacts, so use with care. # box_drawing_scale 0.001, 1, 1.5, 2 #: The sizes of the lines used for the box drawing Unicode characters. #: These values are in pts. They will be scaled by the monitor DPI to #: arrive at a pixel value. There must be four values corresponding to #: thin, normal, thick, and very thick lines. # undercurl_style thin-sparse #: The style with which undercurls are rendered. This option takes the #: form (thin|thick)-(sparse|dense). Thin and thick control the #: thickness of the undercurl. Sparse and dense control how often the #: curl oscillates. With sparse the curl will peak once per character, #: with dense twice. #: }}} #: Cursor customization {{{ # cursor #cccccc #: Default cursor color. If set to the special value none the cursor #: will be rendered with a "reverse video" effect. It's color will be #: the color of the text in the cell it is over and the text will be #: rendered with the background color of the cell. Note that if the #: program running in the terminal sets a cursor color, this takes #: precedence. Also, the cursor colors are modified if the cell #: background and foreground colors have very low contrast. # cursor_text_color #111111 #: The color of text under the cursor. If you want it rendered with #: the background color of the cell underneath instead, use the #: special keyword: background. Note that if cursor is set to none #: then this option is ignored. # cursor_shape block #: The cursor shape can be one of block, beam, underline. Note that #: when reloading the config this will be changed only if the cursor #: shape has not been set by the program running in the terminal. This #: sets the default cursor shape, applications running in the terminal #: can override it. In particular, shell integration #: in kitty sets #: the cursor shape to beam at shell prompts. You can avoid this by #: setting shell_integration to no-cursor. # cursor_beam_thickness 1.5 #: The thickness of the beam cursor (in pts). # cursor_underline_thickness 2.0 #: The thickness of the underline cursor (in pts). # cursor_blink_interval -1 #: The interval to blink the cursor (in seconds). Set to zero to #: disable blinking. Negative values mean use system default. Note #: that the minimum interval will be limited to repaint_delay. # cursor_stop_blinking_after 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 or #: set to 0 if there is no cursor, for example, when showing the last #: command output. # scrollback_pager_history_size 0 #: Separate scrollback history size (in MB), used only for browsing #: the scrollback buffer with pager. This separate buffer is not #: available for interactive scrolling but will be piped to the pager #: program when viewing scrollback buffer in a separate window. The #: current implementation stores the data in UTF-8, so approximatively #: 10000 lines per megabyte at 100 chars per line, for pure ASCII, #: unformatted text. A value of zero or less disables this feature. #: The maximum allowed size is 4GB. Note that on config reload if this #: is changed it will only affect newly created windows, not existing #: ones. # scrollback_fill_enlarged_window no #: Fill new space with lines from the scrollback buffer after #: enlarging a window. # wheel_scroll_multiplier 5.0 #: Multiplier for the number of lines scrolled by the mouse wheel. #: Note that this is only used for low precision scrolling devices, #: not for high precision scrolling devices on platforms such as macOS #: and Wayland. Use negative numbers to change scroll direction. See #: also wheel_scroll_min_lines. # wheel_scroll_min_lines 1 #: The minimum number of lines scrolled by the mouse wheel. The scroll #: multiplier wheel_scroll_multiplier only takes effect after it #: reaches this number. Note that this is only used for low precision #: scrolling devices like wheel mice that scroll by very small amounts #: when using the wheel. With a negative number, the minimum number of #: lines will always be added. # touch_scroll_multiplier 1.0 #: Multiplier for the number of lines scrolled by a touchpad. Note #: that this is only used for high precision scrolling devices on #: platforms such as macOS and Wayland. Use negative numbers to change #: scroll direction. #: }}} #: Mouse {{{ # mouse_hide_wait 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, straight, double, curly, dotted, dashed. # open_url_with default #: The program to open clicked URLs. The special value default with #: first look for any URL handlers defined via the open_actions #: facility and if non #: are found, it will use the Operating System's default URL handler #: (open on macOS and xdg-open on Linux). # url_prefixes file ftp ftps gemini git gopher http https irc ircs kitty mailto news sftp ssh #: The set of URL prefixes to look for when detecting a URL under the #: mouse cursor. # detect_urls 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 that are #: legal in URLs are allowed. # show_hyperlink_targets no #: When the mouse hovers over a terminal hyperlink, show the actual #: URL that will be activated when the hyperlink is clicked. # copy_on_select no #: Copy to clipboard or a private buffer on select. With this set to #: clipboard, selecting text with the mouse will cause the text to be #: copied to clipboard. Useful on platforms such as macOS that do not #: have the concept of primary selection. You can instead specify a #: name such as a1 to copy to a private kitty buffer. Map a shortcut #: with the paste_from_buffer action to paste from this private #: buffer. For example:: #: copy_on_select a1 #: map shift+cmd+v paste_from_buffer a1 #: Note that copying to the clipboard is a security risk, as all #: programs, including websites open in your browser can read the #: contents of the system clipboard. # paste_actions quote-urls-at-prompt #: A comma separated list of actions to take when pasting text into #: the terminal. The supported paste actions are: #: quote-urls-at-prompt: #: If the text being pasted is a URL and the cursor is at a shell prompt, #: automatically quote the URL (needs shell_integration). #: confirm: #: Confirm the paste if bracketed paste mode is not active or there is more #: a large amount of text being pasted. #: filter: #: Run the filter_paste() function from the file paste-actions.py in #: the kitty config directory on the pasted text. The text returned by the #: function will be actually pasted. # strip_trailing_spaces never #: Remove spaces at the end of lines when copying to clipboard. A #: value of smart will do it when using normal selections, but not #: rectangle selections. A value of always will always do it. # select_by_word_characters @-./_~?&=%+# #: Characters considered part of a word when double clicking. In #: addition to these characters any character that is marked as an #: alphanumeric character in the Unicode database will be matched. # select_by_word_characters_forward #: Characters considered part of a word when extending the selection #: forward on double clicking. In addition to these characters any #: character that is marked as an alphanumeric character in the #: Unicode database will be matched. #: If empty (default) select_by_word_characters will be used for both #: directions. # click_interval -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 mapped to perform arbitrary actions. The #: syntax is: #: .. code-block:: none #: mouse_map button-name event-type modes action #: Where button-name is one of left, middle, right, b1 ... b8 with #: added keyboard modifiers. For example: ctrl+shift+left refers to #: holding the Ctrl+Shift keys while clicking with the left mouse #: button. The value b1 ... b8 can be used to refer to up to eight #: buttons on a mouse. #: event-type is one of press, release, doublepress, triplepress, #: click, doubleclick. modes indicates whether the action is performed #: when the mouse is grabbed by the program running in the terminal, #: or not. The values are grabbed or ungrabbed or a comma separated #: combination of them. grabbed refers to when the program running in #: the terminal has requested mouse events. Note that the click and #: double click events have a delay of click_interval to disambiguate #: from double and triple presses. #: You can run kitty with the kitty --debug-input command line option #: to see mouse events. See the builtin actions below to get a sense #: of what is possible. #: If you want to unmap an action, map it to no_op. For example, to #: disable opening of URLs with a plain click:: #: mouse_map left click ungrabbed no_op #: See all the mappable actions including mouse actions here #: . #: .. note:: #: Once a selection is started, releasing the button that started it will #: automatically end it and no release event will be dispatched. # clear_all_mouse_actions no #: Remove all mouse action definitions up to this point. Useful, for #: instance, to remove the default mouse actions. #: Click the link under the mouse or move the cursor # mouse_map left click ungrabbed mouse_handle_click selection link prompt #:: First check for a selection and if one exists do nothing. Then #:: check for a link under the mouse cursor and if one exists, click #:: it. Finally check if the click happened at the current shell #:: prompt and if so, move the cursor to the click location. Note #:: that this requires shell integration #:: to work. #: Click the link under the mouse or move the cursor even when grabbed # mouse_map shift+left click grabbed,ungrabbed mouse_handle_click selection link prompt #:: Same as above, except that the action is performed even when the #:: mouse is grabbed by the program running in the terminal. #: Click the link under the mouse cursor # mouse_map ctrl+shift+left release grabbed,ungrabbed mouse_handle_click link #:: Variant with Ctrl+Shift is present because the simple click based #:: version has an unavoidable delay of click_interval, to #:: disambiguate clicks from double clicks. #: Discard press event for link click # mouse_map ctrl+shift+left press grabbed discard_event #:: Prevent this press event from being sent to the program that has #:: grabbed the mouse, as the corresponding release event is used to #:: open a URL. #: Paste from the primary selection # mouse_map middle release ungrabbed paste_from_selection #: Start selecting text # mouse_map left press ungrabbed mouse_selection normal #: Start selecting text in a rectangle # mouse_map ctrl+alt+left press ungrabbed mouse_selection rectangle #: Select a word # mouse_map left doublepress ungrabbed mouse_selection word #: Select a line # mouse_map left triplepress ungrabbed mouse_selection line #: Select line from point # mouse_map ctrl+alt+left triplepress ungrabbed mouse_selection line_from_point #:: Select from the clicked point to the end of the line. #: Extend the current selection # mouse_map right press ungrabbed mouse_selection extend #:: If you want only the end of the selection to be moved instead of #:: the nearest boundary, use move-end instead of extend. #: Paste from the primary selection even when grabbed # mouse_map shift+middle release ungrabbed,grabbed paste_selection # mouse_map shift+middle press grabbed discard_event #: Start selecting text even when grabbed # mouse_map shift+left press ungrabbed,grabbed mouse_selection normal #: Start selecting text in a rectangle even when grabbed # mouse_map ctrl+shift+alt+left press ungrabbed,grabbed mouse_selection rectangle #: Select a word even when grabbed # mouse_map shift+left doublepress ungrabbed,grabbed mouse_selection word #: Select a line even when grabbed # mouse_map shift+left triplepress ungrabbed,grabbed mouse_selection line #: Select line from point even when grabbed # mouse_map ctrl+shift+alt+left triplepress ungrabbed,grabbed mouse_selection line_from_point #:: Select from the clicked point to the end of the line even when #:: grabbed. #: Extend the current selection even when grabbed # mouse_map shift+right press ungrabbed,grabbed mouse_selection extend #: Show clicked command output in pager # mouse_map ctrl+shift+right press ungrabbed mouse_show_command_output #:: Requires shell integration #:: to work. #: }}} #: }}} #: Performance tuning {{{ # repaint_delay 10 #: Delay between screen updates (in milliseconds). Decreasing it, #: increases frames-per-second (FPS) at the cost of more CPU usage. #: The default value yields ~100 FPS which is more than sufficient for #: most uses. Note that to actually achieve 100 FPS, you have to #: either set sync_to_monitor to no or use a monitor with a high #: refresh rate. Also, to minimize latency when there is pending input #: to be processed, this option is ignored. # input_delay 3 #: Delay before input from the program running in the terminal is #: processed (in milliseconds). Note that decreasing it will increase #: responsiveness, but also increase CPU usage and might cause flicker #: in full screen programs that redraw the entire screen on each loop, #: because kitty is so fast that partial screen updates will be drawn. # sync_to_monitor yes #: Sync screen updates to the refresh rate of the monitor. This #: prevents screen tearing #: when scrolling. #: However, it limits the rendering speed to the refresh rate of your #: monitor. With a very high speed mouse/high keyboard repeat rate, #: you may notice some slight input latency. If so, set this to no. #: }}} #: Terminal bell {{{ # enable_audio_bell yes #: The audio bell. Useful to disable it in environments that require #: silence. # visual_bell_duration 0.0 #: The visual bell duration (in seconds). Flash the screen when a bell #: occurs for the specified number of seconds. Set to zero to disable. # visual_bell_color none #: The color used by visual bell. Set to none will fall back to #: selection background color. If you feel that the visual bell is too #: bright, you can set it to a darker color. # window_alert_on_bell yes #: Request window attention on bell. Makes the dock icon bounce on #: macOS or the taskbar flash on linux. # bell_on_tab "🔔 " #: Some text or a Unicode symbol to show on the tab if a window in the #: tab that does not have focus has a bell. If you want to use leading #: or trailing spaces, surround the text with quotes. See #: tab_title_template for how this is rendered. #: For backwards compatibility, values of yes, y and true are #: converted to the default bell symbol and no, n, false and none are #: converted to the empty string. # command_on_bell none #: Program to run when a bell occurs. The environment variable #: KITTY_CHILD_CMDLINE can be used to get the program running in the #: window in which the bell occurred. # bell_path none #: Path to a sound file to play as the bell sound. If set to none, the #: system default bell sound is used. Must be in a format supported by #: the operating systems sound API, such as WAV or OGA on Linux #: (libcanberra) or AIFF, MP3 or WAV on macOS (NSSound) #: }}} #: Window layout {{{ # remember_window_size yes # initial_window_width 640 # initial_window_height 400 #: If enabled, the OS Window size will be remembered so that new #: instances of kitty will have the same size as the previous #: instance. If disabled, the OS Window will initially have size #: configured by initial_window_width/height, in pixels. You can use a #: suffix of "c" on the width/height values to have them interpreted #: as number of cells instead of pixels. # enabled_layouts * #: The enabled window layouts. A comma separated list of layout names. #: The special value all means all layouts. The first listed layout #: will be used as the startup layout. Default configuration is all #: layouts in alphabetical order. For a list of available layouts, see #: the layouts . # window_resize_step_cells 2 # window_resize_step_lines 2 #: The step size (in units of cell width/cell height) to use when #: resizing kitty windows in a layout with the shortcut #: start_resizing_window. The cells value is used for horizontal #: resizing, and the lines value is used 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 #: borders that separate the window from a neighbor are drawn. Note #: that setting a non-zero window_margin_width overrides this and #: causes all borders to be drawn. # window_margin_width 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 to use when only a single window is visible (in #: pts). Negative values will cause the value of window_margin_width #: to be used instead. A single value sets all four sides. Two values #: set the vertical and horizontal sides. Three values set top, #: horizontal and bottom. Four values set top, right, bottom and left. # window_padding_width 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 #: only at 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 option when reloading config are undefined. # window_logo_path none #: Path to a logo image. Must be in PNG format. Relative paths are #: interpreted relative to the kitty config directory. The logo is #: displayed in a corner of every kitty window. The position is #: controlled by window_logo_position. Individual windows can be #: configured to have different logos either using the launch action #: or the remote control facility. # window_logo_position bottom-right #: Where to position the window logo in the window. The value can be #: one of: top-left, top, top-right, left, center, right, bottom-left, #: bottom, bottom-right. # window_logo_alpha 0.5 #: The amount the logo should be faded into the background. With zero #: being fully faded and one being fully opaque. # resize_debounce_time 0.1 #: The time to wait before redrawing the screen when a resize event is #: received (in seconds). On platforms such as macOS, where the #: operating system sends events corresponding to the start and end of #: a resize, this number is ignored. # resize_draw_strategy 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 initial_window_width #: and initial_window_height in number of cells, this option can be #: used to keep the margins as small as possible when resizing the OS #: window. Note that this does not currently work on Wayland. # visual_window_select_characters 1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ #: The list of characters for visual window selection. For example, #: for selecting a window to focus on with focus_visible_window. The #: value should be a series of unique numbers or alphabets, case #: insensitive, from the set [0-9A-Z]. Specify your preference as a #: string of characters. # confirm_os_window_close -1 #: Ask for confirmation when closing an OS window or a tab with at #: least this number of kitty windows in it by window manager (e.g. #: clicking the window close button or pressing the operating system #: shortcut to close windows) or by the close_tab action. A value of #: zero disables confirmation. This confirmation also applies to #: requests to quit the entire application (all OS windows, via the #: quit action). Negative values are converted to positive ones, #: however, with shell_integration enabled, using negative values #: means windows sitting at a shell prompt are not counted, only #: windows where some command is currently running. Note that if you #: want confirmation when closing individual windows, you can map the #: close_window_with_confirmation action. #: }}} #: Tab bar {{{ # tab_bar_edge bottom #: The 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. #: 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 also tab_fade) #: slant #: Tabs look like the tabs in a physical file. #: separator #: Tabs are separated by a configurable separator. (See also #: tab_separator) #: powerline #: Tabs are shown as a continuous line with "fancy" separators. #: (See also tab_powerline_style) #: custom #: A user-supplied Python function called draw_tab is loaded from the file #: tab_bar.py in the kitty config directory. For examples of how to #: write such a function, see the functions named draw_tab_with_* in #: kitty's source code: kitty/tab_bar.py. See also #: this discussion #: for examples from kitty users. #: hidden #: The tab bar is hidden. If you use this, you might want to create a mapping #: for the select_tab action which presents you with a list of tabs and #: allows for easy switching to a tab. # tab_bar_align left #: The horizontal alignment of the tab bar, can be one of: left, #: center, right. # 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, 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. See #: tab_title_template for how this is rendered. # tab_title_max_length 0 #: The maximum number of cells that can be used to render the text in #: a tab. A value of zero means that no limit is applied. # tab_title_template "{fmt.fg.red}{bell_symbol}{activity_symbol}{fmt.fg.tab}{title}" #: A template to render the tab title. The default just renders the #: title with optional symbols for bell and activity. If you wish to #: include the tab-index as well, use something like: {index}:{title}. #: Useful if you have shortcuts mapped for goto_tab N. If you prefer #: to see the index as a superscript, use {sup.index}. All data #: available is: #: title #: The current tab title. #: index #: The tab index useable with goto_tab N goto_tab shortcuts. #: layout_name #: The current layout name. #: num_windows #: The number of windows in the tab. #: num_window_groups #: The number of window groups (not counting overlay windows) in the tab. #: tab.active_wd #: The working directory of the currently active window in the tab (expensive, #: requires syscall). Use active_oldest_wd to get the directory of the oldest foreground process rather than the newest. #: tab.active_exe #: The name of the executable running in the foreground of the currently active window in the tab (expensive, #: requires syscall). Use active_oldest_exe for the oldest foreground process. #: max_title_length #: The maximum title length available. #: Note that formatting is done by Python's string formatting #: machinery, so you can use, for instance, {layout_name[:2].upper()} #: to show only the first two letters of the layout name, upper-cased. #: If you want to style the text, you can use styling directives, for #: example: #: `{fmt.fg.red}red{fmt.fg.tab}normal{fmt.bg._00FF00}greenbg{fmt.bg.tab}`. #: Similarly, for bold and italic: #: `{fmt.bold}bold{fmt.nobold}normal{fmt.italic}italic{fmt.noitalic}`. #: Note that for backward compatibility, if {bell_symbol} or #: {activity_symbol} are not present in the template, they are #: prepended to it. # active_tab_title_template 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. # tab_bar_margin_color none #: Color for the tab bar margin area. Defaults to using the terminal #: background color for margins above and below the tab bar. For side #: margins the default color is chosen to match the background color #: of the neighboring tab. #: }}} #: Color scheme {{{ # foreground #dddddd # background #000000 #: The foreground and background colors. # background_opacity 1.0 #: The opacity of the background. A number between zero and one, where #: one is opaque and zero is fully transparent. This will only work if #: supported by the OS (for instance, when using a compositor under #: X11). Note that it only sets the background color's opacity in #: cells that have the same background color as the default terminal #: background, so that things like the status bar in vim, powerline #: prompts, etc. still look good. But it means that if you use a color #: theme with a background color in your editor, it will not be #: rendered as transparent. Instead you should change the default #: background color in your kitty config and not use a background #: color in the editor color scheme. Or use the escape codes to set #: the terminals default colors in a shell script to launch your #: editor. Be aware that using a value less than 1.0 is a (possibly #: significant) performance hit. If you want to dynamically change #: transparency of windows, set dynamic_background_opacity to yes #: (this is off by default as it has a performance cost). Changing #: this option when reloading the config will only work if #: dynamic_background_opacity was enabled in the original config. # background_image none #: Path to a background image. Must be in PNG format. # background_image_layout tiled #: Whether to tile, scale or clamp the background image. The value can #: be one of tiled, mirror-tiled, scaled, clamped or centered. # background_image_linear 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 option by reloading the config is not supported. # background_tint 0.0 #: How much to tint the background image by the background color. This #: option makes it easier to read the text. Tinting is done using the #: current background color for each window. This option applies only #: if background_opacity is set and transparent windows are supported #: or background_image is set. # background_tint_gaps 1.0 #: How much to tint the background image at the window gaps by the #: background color, after applying background_tint. Since this is #: multiplicative with background_tint, it can be used to lighten the #: tint over the window gaps for a *separated* look. # dim_opacity 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 # selection_background #fffacd #: The foreground and background colors for text selected with the #: mouse. Setting both of these to none will cause a "reverse video" #: effect for selections, where the selection will be the cell text #: color and the text will become the cell background color. Setting #: only selection_foreground to none will cause the foreground color #: to be used unchanged. Note that these colors can be overridden by #: the program running in the terminal. #: The color table {{{ #: The 256 terminal colors. There are 8 basic colors, each color has a #: dull and bright version, for the first 16 colors. You can set the #: remaining 240 colors as color16 to color255. # color0 #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 based text editor (such as vim or nano) to use when #: editing the kitty config file or similar tasks. #: The default value of . means to use the environment variables #: VISUAL and EDITOR in that order. If these variables aren't set, #: kitty will run your shell ($SHELL -l -i -c env) to see if your #: shell startup rc files set VISUAL or EDITOR. If that doesn't work, #: kitty will cycle through various known editors (vim, emacs, etc.) #: and take the first one that exists on your system. # close_on_child_death no #: Close the window when the child process (shell) exits. With the #: default value no, the terminal will remain open when the child #: exits as long as there are still processes outputting to the #: terminal (for example disowned or backgrounded processes). When #: enabled with yes, the window will close as soon as the child #: process exits. Note that setting it to yes means that any #: background processes still using the terminal can fail silently #: because their stdout/stderr/stdin no longer work. # remote_control_password #: Allow other programs to control kitty using passwords. This option #: can be specified multiple times to add multiple passwords. If no #: passwords are present kitty will ask the user for permission if a #: program tries to use remote control with a password. A password can #: also *optionally* be associated with a set of allowed remote #: control actions. For example:: #: remote_control_password "my passphrase" get-colors set-colors focus-window focus-tab #: Only the specified actions will be allowed when using this #: password. Glob patterns can be used too, for example:: #: remote_control_password "my passphrase" set-tab-* resize-* #: To get a list of available actions, run:: #: kitty @ --help #: A set of actions to be allowed when no password is sent can be #: specified by using an empty password, for example:: #: remote_control_password "" *-colors #: Finally, the path to a python module can be specified that provides #: a function is_cmd_allowed that is used to check every remote #: control command. See rc_custom_auth #: #: for details. For example:: #: remote_control_password "my passphrase" my_rc_command_checker.py #: Relative paths are resolved from the kitty configuration directory. # allow_remote_control no #: Allow other programs to control kitty. If you turn this on, other #: programs can control all aspects of kitty, including sending text #: to kitty windows, opening new windows, closing windows, reading the #: content of windows, etc. Note that this even works over SSH #: connections. The default setting of no prevents any form of remote #: control. The meaning of the various values are: #: password #: Remote control requests received over both the TTY device and the socket are #: confirmed based on passwords, see remote_control_password. #: socket-only #: Remote control requests received over a socket are accepted unconditionally. #: Requests received over the TTY are denied. See listen_on. #: socket #: Remote control requests received over a socket are accepted unconditionally. #: Requests received over the TTY are confirmed based on password. #: no #: Remote control is completely disabled. #: yes #: Remote control requests are always accepted. # listen_on none #: Listen to the specified UNIX socket for remote control connections. #: Note that this will apply to all kitty instances. It can be #: overridden by the kitty --listen-on command line option, which also #: supports listening on a TCP socket. This option accepts only UNIX #: sockets, such as unix:${TEMP}/mykitty or unix:@mykitty (on Linux). #: Environment variables are expanded and relative paths are resolved #: with respect to the temporary directory. If {kitty_pid} is present, #: then it is replaced by the PID of the kitty process, otherwise the #: PID of the kitty process is appended to the value, with a hyphen. #: See the help for kitty --listen-on for more details. Note that this #: will be ignored unless allow_remote_control is set to either: yes, #: socket or socket-only. Changing this option by reloading the config #: is not supported. # env #: Specify the environment variables to be set in all child processes. #: Using the name with an equal sign (e.g. env VAR=) will set it to #: the empty string. Specifying only the name (e.g. env VAR) will #: remove the variable from the child process' environment. Note that #: environment variables are expanded recursively, for example:: #: env VAR1=a #: env VAR2=${HOME}/${VAR1}/b #: The value of VAR2 will be /a/b. # watcher #: Path to python file which will be loaded for watchers #: . Can be #: specified more than once to load multiple watchers. The watchers #: will be added to every kitty window. Relative paths are resolved #: relative to the kitty config directory. Note that reloading the #: config will only affect windows created after the reload. # exe_search_path #: Control where kitty finds the programs to run. The default search #: order is: First search the system wide PATH, then ~/.local/bin and #: ~/bin. If still not found, the PATH defined in the login shell #: after sourcing all its startup files is tried. Finally, if present, #: the PATH specified by the env option is tried. #: This option allows you to prepend, append, or remove paths from #: this search order. It can be specified multiple times for multiple #: paths. A simple path will be prepended to the search order. A path #: that starts with the + sign will be append to the search order, #: after ~/bin above. A path that starts with the - sign will be #: removed from the entire search order. For example:: #: exe_search_path /some/prepended/path #: exe_search_path +/some/appended/path #: exe_search_path -/some/excluded/path # update_check_interval 24 #: The interval to periodically check if an update to kitty is #: available (in hours). If an update is found, a system notification #: is displayed informing you of the available update. The default is #: to check every 24 hours, set to zero to disable. Update checking is #: only done by the official binary builds. Distro packages or source #: builds do not do update checking. Changing this option by reloading #: the config is not supported. # startup_session none #: Path to a session file to use for all kitty instances. Can be #: overridden by using the kitty --session command line option for #: individual instances. See sessions #: in the kitty #: documentation for details. Note that relative paths are interpreted #: with respect to the kitty config directory. Environment variables #: in the path are expanded. Changing this option by reloading the #: config is not supported. # clipboard_control write-clipboard write-primary read-clipboard-ask read-primary-ask #: Allow programs running in kitty to read and write from the #: clipboard. You can control exactly which actions are allowed. The #: possible actions are: write-clipboard, read-clipboard, write- #: primary, read-primary, read-clipboard-ask, read-primary-ask. The #: default is to allow writing to the clipboard and primary selection #: and to ask for permission when a program tries to read from the #: clipboard. Note that disabling the read confirmation is a security #: risk as it means that any program, even the ones running on a #: remote server via SSH can read your clipboard. See also #: clipboard_max_size. # clipboard_max_size 512 #: The maximum size (in MB) of data from programs running in kitty #: that will be stored for writing to the system clipboard. A value of #: zero means no size limit is applied. See also clipboard_control. # file_transfer_confirmation_bypass #: The password that can be supplied to the file transfer kitten #: to skip the #: transfer confirmation prompt. This should only be used when #: initiating transfers from trusted computers, over trusted networks #: or encrypted transports, as it allows any programs running on the #: remote machine to read/write to the local filesystem, without #: permission. # allow_hyperlinks yes #: Process hyperlink escape sequences (OSC 8). If disabled OSC 8 #: escape sequences are ignored. Otherwise they become clickable #: links, that you can click with the mouse or by using the hints #: kitten . The #: special value of ask means that kitty will ask before opening the #: link when clicked. # shell_integration enabled #: Enable shell integration on supported shells. This enables features #: such as jumping to previous prompts, browsing the output of the #: previous command in a pager, etc. on supported shells. Set to #: disabled to turn off shell integration, completely. It is also #: possible to disable individual features, set to a space separated #: list of these values: no-rc, no-cursor, no-title, no-cwd, no- #: prompt-mark, no-complete. See Shell integration #: for details. # allow_cloning ask #: Control whether programs running in the terminal can request new #: windows to be created. The canonical example is clone-in-kitty #: . #: By default, kitty will ask for permission for each clone request. #: Allowing cloning unconditionally gives programs running in the #: terminal (including over SSH) permission to execute arbitrary code, #: as the user who is running the terminal, on the computer that the #: terminal is running on. # clone_source_strategies venv,conda,env_var,path #: Control what shell code is sourced when running clone-in-kitty in #: the newly cloned window. The supported strategies are: #: venv #: Source the file $VIRTUAL_ENV/bin/activate. This is used by the #: Python stdlib venv module and allows cloning venvs automatically. #: conda #: Run conda activate $CONDA_DEFAULT_ENV. This supports the virtual #: environments created by conda. #: env_var #: Execute the contents of the environment variable #: KITTY_CLONE_SOURCE_CODE with eval. #: path #: Source the file pointed to by the environment variable #: KITTY_CLONE_SOURCE_PATH. #: This option must be a comma separated list of the above values. #: This only source the first valid one in the above order. # 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 #: 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 #: The color of the kitty window's titlebar on macOS. A value of #: system means to use the default system color, light or dark can #: also be used to set it explicitly. A value of background means to #: use the background color of the currently active window and finally #: you can use an arbitrary color, such as #12af59 or red. WARNING: #: This option works by using a hack when arbitrary color (or #: background) is configured, as there is no proper Cocoa API for it. #: It sets the background color of the entire window and makes the #: titlebar transparent. As such it is incompatible with #: background_opacity. If you want to use both, you are probably #: better off just hiding the titlebar with hide_window_decorations. # macos_option_as_alt no #: Use the Option key as an Alt key on macOS. With this set to no, #: kitty will use the macOS native Option+Key to enter Unicode #: character behavior. This will break any Alt+Key keyboard shortcuts #: in your terminal programs, but you can use the macOS Unicode input #: technique. You can use the values: left, right or both to use only #: the left, right or both Option keys as Alt, instead. Note that #: kitty itself always treats Option the same as Alt. This means you #: cannot use this option to configure different kitty shortcuts for #: Option+Key vs. Alt+Key. Also, any kitty shortcuts using #: Option/Alt+Key will take priority, so that any such key presses #: will not be passed to terminal programs running inside kitty. #: Changing this option by reloading the config is not supported. # macos_hide_from_tasks no #: Hide the kitty window from running tasks on macOS (⌘+Tab and the #: Dock). Changing this option by reloading the config is not #: supported. # macos_quit_when_last_window_closed no #: Have kitty quit when all the top-level windows are closed on macOS. #: By default, kitty will stay running, even with no open windows, as #: is the expected behavior on macOS. # macos_window_resizable yes #: Disable this if you want kitty top-level OS windows to not be #: resizable on macOS. Changing this option by reloading the config #: will only affect newly created OS windows. # macos_thicken_font 0 #: Draw an extra border around the font with the given width, to #: increase legibility at small font sizes on macOS. For example, a #: value of 0.75 will result in rendering that looks similar to sub- #: pixel antialiasing at common font sizes. # macos_traditional_fullscreen no #: Use the macOS traditional full-screen transition, that is faster, #: but less pretty. # macos_show_window_title_in all #: Control where the window title is displayed on macOS. A value of #: window will show the title of the currently active window at the #: top of the macOS window. A value of menubar will show the title of #: the currently active window in the macOS global menu bar, making #: use of otherwise wasted space. A value of all will show the title #: in both places, and none hides the title. See #: macos_menubar_title_max_length for how to control the length of the #: title in the menu bar. # macos_menubar_title_max_length 0 #: The maximum number of characters from the window title to show in #: the macOS global menu bar. Values less than one means that there is #: no maximum limit. # macos_custom_beam_cursor no #: Use a custom mouse cursor for macOS that is easier to see on both #: light and dark backgrounds. Nowadays, the default macOS cursor #: already comes with a white border. WARNING: this might make your #: mouse cursor invisible on dual GPU machines. Changing this option #: by reloading the config is not supported. # macos_colorspace srgb #: The colorspace in which to interpret terminal colors. The default #: of srgb will cause colors to match those seen in web browsers. The #: value of default will use whatever the native colorspace of the #: display is. The value of displayp3 will use Apple's special #: snowflake display P3 color space, which will result in over #: saturated (brighter) colors with some color shift. Reloading #: configuration will change this value only for newly created OS #: windows. # linux_display_server auto #: Choose between Wayland and X11 backends. By default, an appropriate #: backend based on the system state is chosen automatically. Set it #: to x11 or wayland to force the choice. Changing this option by #: reloading the config is not supported. #: }}} #: Keyboard shortcuts {{{ #: Keys are identified simply by their lowercase Unicode characters. #: For example: a for the A key, [ for the left square bracket key, #: etc. For functional keys, such as Enter or Escape, the names are #: present at Functional key definitions #: . #: For modifier keys, the names are ctrl (control, ⌃), shift (⇧), alt #: (opt, option, ⌥), super (cmd, command, ⌘). See also: 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, #: 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: 0x61 native_code: 0x61 action: PRESS mods: none text: 'a' #: Here, the key name for the A key is 0x61 and you can use it with:: #: map ctrl+0x61 something #: to map Ctrl+A to something. #: You can use the special action no_op to unmap a keyboard shortcut #: that is assigned in the default configuration:: #: map kitty_mod+space no_op #: If you would like kitty to completely ignore a key event, not even #: sending it to the program running in the terminal, map it to #: discard_event:: #: map kitty_mod+f1 discard_event #: You can combine multiple actions to be triggered by a single #: shortcut with combine action, using the syntax below:: #: map key combine 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 with the syntax shown below:: #: map key1>key2>key3 action #: For example:: #: map ctrl+f>2 set_font_size 20 #: The full list of actions that can be mapped to key presses is #: available here . # kitty_mod ctrl+shift #: Special modifier key alias for default shortcuts. You can change #: the value of this option to alter all default shortcuts that use #: kitty_mod. # clear_all_shortcuts no #: Remove all shortcut definitions up to this point. Useful, for #: instance, to remove the default shortcuts. # action_alias #: E.g. action_alias launch_tab launch --type=tab --cwd=current #: Define action aliases to avoid repeating the same options in #: multiple mappings. Aliases can be defined for any action and will #: be expanded recursively. For example, the above alias allows you to #: create mappings to launch a new tab in the current working #: directory without duplication:: #: map f1 launch_tab vim #: map f2 launch_tab emacs #: Similarly, to alias kitten invocation:: #: action_alias hints kitten hints --hints-offset=0 # kitten_alias #: E.g. kitten_alias hints hints --hints-offset=0 #: Like action_alias above, but specifically for kittens. Generally, #: prefer to use action_alias. This option is a legacy version, #: present for backwards compatibility. It causes all invocations of #: the aliased kitten to be substituted. So the example above will #: cause all invocations of the hints kitten to have the --hints- #: offset=0 option applied. #: Clipboard {{{ #: Copy to clipboard # map kitty_mod+c copy_to_clipboard # map cmd+c copy_to_clipboard #:: There is also a copy_or_interrupt action that can be optionally #:: mapped to Ctrl+C.
