So let me know how do you write 5 languages properly…

I don't understand what you're asking or why it's relevant to what I said. Did you mean to reply to someone else, or did you think that I was the same commenter as someone else?

Are you talking about changing keymaps or just different keymaps?

The last you setup in your DE and the first you use xkb as before. (Or at least that’s how I did it before)

I am not trying to change layout, no.

Bravo, e come fai con Øåä e questo genere di lettere?
