Now I have
setxkbmap -model acer_laptop -layout lang1,lang2 -variant , setxkbmap -option -option grp:caps_toggle
in a startup script. It works well for two languages.
I want to have 4 languages (like as in
-layout lang1,lang2,lang3,lang4), hovewer I want Caps Lock to keep on switching between lang1 and lang2 and use some other method to loop thought all input languages.
How to do it? Can I call "setxkbmap" to only set current language (not affecting the Caps Lock cycle) so I can bind it to a keystroke?
