Looks great!

Couple of issues:

1. Holding "Q" to toggle between vibrate and normal profiles was left out.

2. "hold mute to lock keyboard" is kind of confusing. It locks the keyboard, but does not lock the phone itself. Holding "A" would put the phone into lock mode. This is important for people who's phones are password protected. Because pressing mute puts it into standby, which is not password protected.
