I notice that the Magic key (or Setup key for some of you guys) on the Cinema7 can function as a shift key and I mapped something to the shifted PrevChannel button using the following sequence:

Magic*_**9*9*4* **Magic*x*x*x*Magic*PrevCh* **

now whenever I press Magic*PrevCh* it will send discrete off signal to my DVD player. This is all fine and dandy until the time when I want to clean up that button. According to the instruction, I have to do the Magic 994 and press the PrevCh twice, but it only set the normal PrevCh button back to default, shifted PrevCh still turns off my DVD.

What can I do to get ride of the mapping?
