GX1 programmable button problem
There are a fairly limited number of functions you can add to the Q Menu for easy access. Unfortunately, focus assist isn't one of them. You might try setting it as part of a custom shooting mode (C1 or C2 on the mode dial). I don't have the camera with me right now or I'd be able to try it and tell you.
