To all 'Cyrillic-writing' countris

[EOG]

I was always wandering how looks a keybord(on PC and mobile) in Cyrillic-writeing cluntries.
I mean do you have keybords with has latin/roman alphabeth(ABCDEF) or cyrillic alphabeth(??) or both.

If you have only one of this alpgabeth how do you know whith button is a letter in other alphabeth.

Different countries may have different standarts in the letters ordering. Here is Bulgarian standart:

Yeah, we have both alphabets on the keyboard. One key corresponds to a latin letter and to a cyrillic letter.
To change language, we use Alt+Shift or Ctrl+Shift.
