+# lines 25
+
+#: The number of lines shown in the panel. Ignored for background,
+#: centered, and vertical panels. If it has the suffix px then it sets
+#: the height of the panel in pixels instead of lines.
+
+# columns 80
+
+#: The number of columns shown in the panel. Ignored for background,
+#: centered, and horizontal panels. If it has the suffix px then it
+#: sets the width of the panel in pixels instead of columns.
+
+# edge top
+
+#: Which edge of the screen to place the panel on. Note that some
+#: window managers (such as i3) do not support placing docked windows
+#: on the left and right edges. The value background means make the
+#: panel the "desktop wallpaper". Note that when using sway if you set
+#: a background in your sway config it will cover the background drawn
+#: using this kitten. Additionally, there are three more values:
+#: center, center-sized and none. The value center anchors the panel
+#: to all sides and covers the entire display (on macOS the part of
+#: the display not covered by titlebar and dock). The panel can be
+#: shrunk and placed using the margin parameters. The value none
+#: anchors the panel to the top left corner and should be placed using
+#: the margin parameters. Its size is set by lines and columns. The
+#: value center-sized is just like none except that the panel is
+#: centered instead of in the top left corner and the margins have no
+#: effect.
+
+# background_opacity 0.85
+
+#: The background opacity of the window. This works the same as the
+#: kitty option of the same name, it is present here as it has a
+#: different default value for the quick access terminal.
+
+# hide_on_focus_loss no
+
+#: Hide the window when it loses keyboard focus automatically. Using
+#: this option will force focus_policy to on-demand.
+
+# grab_keyboard no
+
+#: Grab the keyboard. This means global shortcuts defined in the OS
+#: will be passed to kitty instead. Useful if you want to create an OS
+#: modal window. How well this works depends on the OS/window
+#: manager/desktop environment. On Wayland it works only if the
+#: compositor implements the inhibit-keyboard-shortcuts protocol
+#: <https://wayland.app/protocols/keyboard-shortcuts-inhibit-
+#: unstable-v1>. On macOS Apple doesn't allow applications to grab the
+#: keyboard without special permissions, so it doesn't work.
+
+# margin_left 0
+
+#: Set the left margin for the panel, in pixels. Has no effect for
+#: right edge panels. Only works on macOS and Wayland compositors that
+#: supports the wlr layer shell protocol.
+
+# margin_right 0
+
+#: Set the right margin for the panel, in pixels. Has no effect for
+#: left edge panels. Only works on macOS and Wayland compositors that
+#: supports the wlr layer shell protocol.
+
+# margin_top 0
+
+#: Set the top margin for the panel, in pixels. Has no effect for
+#: bottom edge panels. Only works on macOS and Wayland compositors
+#: that supports the wlr layer shell protocol.
+
+# margin_bottom 0
+
+#: Set the bottom margin for the panel, in pixels. Has no effect for
+#: top edge panels. Only works on macOS and Wayland compositors that
+#: supports the wlr layer shell protocol.
+
+# kitty_conf
+
+#: Path to config file to use for kitty when drawing the window. Can
+#: be specified multiple times. By default, the normal kitty.conf is
+#: used. Relative paths are resolved with respect to the kitty config
+#: directory.
+
+# kitty_override
+
+#: Override individual kitty configuration options, can be specified
+#: multiple times. Syntax: kitty_override name=value. For example:
+#: kitty_override font_size=20.
+
+# app_id kitty-quick-access
+
+#: On Wayland set the namespace of the layer shell surface. On X11 set
+#: the WM_CLASS assigned to the quick access window. (Linux only)
+
+# output_name
+
+#: The panel can only be displayed on a single monitor (output) at a
+#: time. This allows you to specify which output is used, by name. If
+#: not specified the compositor will choose an output automatically,
+#: typically the last output the user interacted with or the primary
+#: monitor. Run kitten panel --output-name list to get a list of
+#: available outputs. Use listjson for a json encoded output. Note
+#: that on Wayland the output can only be set at panel creation time,
+#: it cannot be changed after creation, nor is there anyway to display
+#: a single panel on all outputs. Please complain to the Wayland
+#: developers about this.
+
+# start_as_hidden no
+
+#: Whether to start the quick access terminal hidden. Useful if you
+#: are starting it as part of system startup.
+
+# focus_policy exclusive
+
+#: On a Wayland compositor that supports the wlr layer shell protocol,
+#: specify the focus policy for keyboard interactivity with the panel.
+#: Please refer to the wlr layer shell protocol documentation for more
+#: details. Note that different Wayland compositors behave very
+#: differently with exclusive, your mileage may vary. On macOS,
+#: exclusive and on-demand are currently the same.
