Amazing! The spoken demo reminds me of Victor Borge's Phonetic Punctuation. This would be such a great way to spend so much time getting slightly more efficient...

I saw her at a keyboard meetup in NYC. She blew my mind with her vim setup: chords representing commands meant that the keystrokes didn't exactly matter: you could have the chord represent an arbitrarily annoying set of keystrokes and have a correspondingly complicated vimrc to handle them. Very cool!!
