    #: Fonts {{{

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

    font_family Hasklug Nerd Font Mono
    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 14.0

    #: 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
    #: <https://github.com/fribidi/fribidi#executable> 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

    #: 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+<code point in hexadecimal>. 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

    # 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
    #: setting you can force kitty to restrict the specified code points
    #: to render in the specified number of cells (defaulting to one
    #: cell). 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 setting.

    # 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 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 <https://harfbuzz.github.io/harfbuzz-hb-
    #: common.html#hb-feature-from-string>.

    #: 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. 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

    #: 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. Note that if cursor is set to none
    #: then this setting 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,
    #: https://sw.kovidgoyal.net/kitty/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

    #: 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 10000

    #: 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, 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,
    #: 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. 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

    #: 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, straight, double, curly, dotted, dashed

    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 (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 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 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. Possibilities 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 https://sw.kovidgoyal.net/kitty/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. 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.

    #: 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

    #: 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

    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

    #: 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

    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

    #: this setting when reloading config are undefined.

    # window_logo_path none

    #: Path to a logo image. Must be in PNG format. Relative paths are

    #: 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 (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.

    visual_window_select_characters 1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ

    #: The list of characters to use for visual window selection (for

    #: tab_title_template for how this is rendered.

    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}. 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.tab}normal{fmt.bg._00FF00}green
    #: bg{fmt.bg.tab}. Similarly, for bold and italic:

    #: 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,

    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.

    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

    # exe_search_path

    #: Control where kitty looks to find programs to run. The default
    #: search order is: First search the system wide PATH, then

    #: 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::

    # clipboard_control write-clipboard write-primary read-clipboard-ask read-primary-ask

    #: Allow programs running in kitty to read and write from the

    #: set of possible actions is: 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 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.

    # file_transfer_confirmation_bypass

    #: A 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 programs running on
    #: the remote machine to read/write to the local filesystem, without
    #: permission.

    # allow_hyperlinks yes

    #: 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, 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, 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. Note that kitty itself
    #: always treats Option the same as Alt. This means you cannot use
    #: this setting 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 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. See
    #: :opt`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 global menubar. Values less than one mean there is no maximum.

    # 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

    #: 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 modifier keys, the names
    #: are ctrl (control, ⌃), shift (⇧), alt (opt, option, ⌥), super (cmd,
    #: command, ⌘). See also: GLFW mods
    #: <https://www.glfw.org/docs/latest/group__mods.html>

    #: On Linux you can also use XKB key names to bind keys that are not
    #: supported by GLFW. See XKB keys
    #: <https://github.com/xkbcommon/libxkbcommon/blob/master/include/xkbcommon/xkbcommon-
    #: keysyms.h> 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

    #: 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, using the syntax below::

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

    #: For example::

    #: map kitty_mod+e combine : new_window : next_layout

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

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

    #: map key1>key2>key3 action

    #: For example::

    #: map ctrl+f>2 set_font_size 20

    #: The full list of actions that can be mapped to key presses is
    #: available here </actions>.

    # 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 definitions seen 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 aliases to avoid repeating the same options in multiple
    #: mappings. Aliases can be defined for any action. Aliases are
    #: 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.

    #: Reset background opacity

    # map kitty_mod+a>d set_background_opacity default

    #: Reset the terminal

    # map kitty_mod+delete clear_terminal reset active
    # map opt+cmd+r clear_terminal reset active

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

    #:: # Reset the terminal
    #:: map f1 clear_terminal reset active
    #:: # Clear the terminal screen by erasing all contents
    #:: map f1 clear_terminal clear active
    #:: # Clear the terminal scrollback by erasing it
    #:: map f1 clear_terminal scrollback active
    #:: # Scroll the contents of the screen into the scrollback
    #:: map f1 clear_terminal scroll active
    #:: # Clear everything up to the line with the cursor
    #:: map f1 clear_terminal to_cursor active

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

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

    #:: .. code-block:: sh

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

    #: Clear up to cursor line

    # map cmd+k clear_terminal to_cursor active

    #: Reload kitty.conf

    # map kitty_mod+f5 load_config_file
    # map ctrl+cmd+, load_config_file

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

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

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

    #: Debug kitty configuration

    # map kitty_mod+f6 debug_config
    # map opt+cmd+, debug_config

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

    #: Send arbitrary text on key presses

    #:: E.g. map ctrl+shift+alt+h send_text all Hello World

    #:: 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
