<input>to activate the numpad seems sound and could be extended to 2nd button for an alpha keypad. Or maybe there's a button in the [modified] jQuery.NumPad to switch to alpha mode. Either way QuickKeys really isn't well-suited to showing a QWERTY keyboard.
Notifiermodule would work. The right hand column would be a little wider to accommodate the buttons but if the screen is huge who cares
