The problem that I'm trying to solve is to have one callback handler for buttons with layout like Qwerty keyboard (we only have
a touch panel and need a keyboard device).

The alphabetic buttons can be upper or lower case, depending on
the case toggle button. I would sure be nice to service over 50
buttons (keys on keyboard) with one callback routine.

The problem is that Button only takes THISBACK and not THISBACK1, so there's no way of sending an argument identifying the key that is pressed.

Also, there is a way to set the label on the button, but not a way to get the lable. Handler could have simply used this, if it knew which key to access.

Is simple way of writing this (sure don't like writing 50 callbacks that all do just about the same thing) ?
