Hello, Leo.

Using [on key label] in VFP is not a very good idea most of the time, because in a very modeless environment it's hardly to predict where the user is located when she presses F1. You can use the KeyPress event instead, that's absolutely local to the control, unless you want to handle it at the form level (see the help on KeyPress for detailed information).

Anyway, I wouldn't recommend using F1, but some other key. F1 is the standard key in Windows for calling an application help (as in VFP). Maybe your app doesn't have one now, but it can be added some day.

I hope this helps,
