That original post came from me. After you added the function, did you go to "Modify the XML" for that button function you just added? It has been a while since I did this, but it was pretty straightforward. You do however add the "Change Button Mapping" to every activity where you want this to work (In my case about 20 activities), then you really want to relabel the "Change Button Function", since you have to edit the XML in each of the button functions, and you'll never keep them straight if they don't have descriptive names.

I added (and renamed) all of "Change Button Functions", and then did the XML edit on all of them, one after another. That way all I had to do was to highlight the old XML, and paste the new command in its place.

Also keep in mind that the opening parenthesis are really "<", but I could not post them like that.

Hope this helps. If not, let me know and I'll try to be more specific.
