When using an input source without Latin characters (e.g. Greek) Vintage command mode is unusable, since the commands are mapped to Latin characters. Vim has the same problem, but you can solve it by mapping every single Latin character to the Greek equivalent in the .vimrc (map a α; map b β; ...).
Since you can't do the same thing on Vintage mode, it should execute the appropriate command regardless of the input language, in the same vein that "cmd+φ" and "cmd+π" trigger the same action as "cmd+f" and "cmd+p".
