I wonder if it would be possible to map vim keybindings to sounds and effectively drive the editor with the mouth when the hands are otherwise occupied. It might be possible to use sounds that compose into pronounceable words with minimal syllables for combinations. What would vim bindings look like as a concise command language suited to human vocalization?

E.g. maybe "dine" maps to d$ and "chine" to c$. So as in keyboard vim you can guess what "dend" and "chend" do.
