The CAPS
key can be mapped to an escape key when pressed once, and a super
(mod4) key when used in combination with other keys.
Create the file /usr/share/X11/xkb/symbols/custom_opts
with the following:
// Make Caps an additional Escape
hidden partial modifier_keys
xkb_symbols "super_esc" {
key <CAPS> { [ Escape ] };
modifier_map Mod4 { <CAPS> };
};
Edit /usr/share/X11/xkb/rules/evdev
and add a new line in the
! option = symbols
section:
custom:super_esc = +custom_opts(super_esc)
Edit /usr/share/X11/xkb/rules/evdev.lst
and add a new line the ! option
section:
custom:super_esc Make Caps Lock an additional ESC and Mod4
Restart your X session and apply the setting using your DE's keyboard layout options.
Open dconf-editor, and navigate to org.gnome.desktop.input-sources
. Add
'custom:super_esc'
to the xkb-options
list. For example, if you have no
other options set, just use ['custom:super_esc']
. If you have other options
set, separate using commas like so: ['compose:ralt', 'custom:super_esc']
.
You can also use the gsettings
command to do this via commandline.
Edit /etc/default/keyboard
and add custom:super_esc
to the XKBOPTIONS
variable (comma-separated).
Most laptops have the alt key really close to the windows key, which can result
in accidental keypresses. I like to use the altwin:alt_win
xkb option (Alt is
mapped to Win and the usual Alt) to make both keys work as alt.
Sweet! Anyone know how to do this with wayland? Maybe libinput settings somehow?
