[qubes-users] How do you safely add foreign language keyboard input to Qubes OS?

Basically I want to be able to switch from the standard Keyboard (English) to Russian and Spanish phonetic keyboards without accidentally locking myself out of the default option (English). I’m working on my Russian so I need to be able to type in Russian, and I also speak Spanish so having that keyboard setup would be nice as well.

Any advice on this topic would be appreciated. Thank you all.
