I'd like to lock keypad on microphone recorder

[KingMatt]

I've got a 8GB Sansa Clip+ and it would be lovely to be able to lock the keypad when you're recording with the microphone, so I can clip it to my shirt pocket, use the recorder and not worry about accidentally pressing buttons which might stop/pause the recording.  Maybe you could use Home+Select to activate/deactivate the lock, the same buttons as with music playback.
