Feature request: Keyboard variant selector

[carbon-starlight]

I use Colemak (setxkbmap us -variant colemak). When I select my keyboard layout I can choose only the default keyboard layout for US.

I also often switch to a Cyrillic layout and back. It would be nice to see some way to switch between several favorite layouts with a shortcut.

@carbon-starlight What OS have you installed EDE on and how?
