True for me. Using spacemacs which uses vi style keybindings, so most shortcuts are key sequences instead of chords. I think its faster for me to press two or three characters on the keyboard my fingers are already on before I move them into place on another keyboard.

Adding a second keyboard and using the Russian layout is a cool method to use a 2nd keyboard that doesn't just duplicate the keys of the first, and likely has more fun applications than just adding more shortcuts to your text editor.
