Is there a way to use another key on the mogul as the power button???

[willieesco28]

I know there may not be a way to do this but um trying to save my self a trip to the sprint store. I recently dropped my mogul and the power key was completly damaged and now I can never put the phone to sleep. So I wanna know if there is a way to map another key to act as the power button?? Any help would be gladly appreciated.
