I don't think there is a public API for dealing with the keyboard at that level. It's quite a big effort (because of international keyboards) but one option would be to listen to UIKeyboardWillShow notifications and overlay the keyboard with transparent UIViews for the buttons you want to listen to. You could capture the touch, then pass it on to the views below (the keyboard) and let it do its thing.

You could even override (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event; in your transparent button. So you capture the fact that it's been touch but return NO anyway so that the keyboard gets the touch.

The difficulty is then to know where each key is, depending on the keyboard types you need to support.
