Tips on playing java games on E71

Are you frustrated that everytime when you are playing java games on E71, you need to press the function key (the bottom left most key) to use the num pad (0-9, *, #) ?

Fred not here is the solution! When you are in game, just press the function key 2 times and you can use the num pad for as long as you wish. Double press again to revert back.
