No problem, but it's generally better to try to find the answer by yourself
first :)

These icons are geared towards Windows applications which don't necessarily
have similar controls. Feel free to choose whatever shortcuts you would use
yourself. That said, the pencil +/- probably mean brush size, or next/previous
brush.

It looks reasonable.

You don't really need getPAD as a function just write this:

PAD=`xsetwacom --list | grep pad | awk '{print  $5  }'`

This is likely due to some special meaning that is assigned to buttons 4-7
and/or xf86-input-evdev behavior.

I would guess every user would like to have their own mappings. Additionally,
they can change GIMP shortcut assignments and other applications would use
different shortcuts.

There's also the imwheel tool which can remap buttons to actions/shortcuts but
it is quite old, doesn't seem to support buttons past #9 and I didn't manage
to make it work.
