All is in title.
Which browser or app are you using, which OS? So the default keyboard shortcuts, such as Quick Add (q) do not work?
Yes Quick Add (q) works only in english keyboard layout.
I assume you're using a Russian layout? If so, that's unfortunately correct, the app requires specifically the letter "q" to be used. It doesn't register the Cyrillic equivalent, but we'll look into this in the future.
