in button mode the touchpad is split into a 3x3 grid for 9 seperate buttons which can be used by the action system like real buttons.
Unify the keymap file for the touchpads in button mode. the target keymap file only needs to worry about real buttons.
(As these ports mature each screen will need to be fixed seperatly to be able to use stylus mode (the lists can already but don't change mode just yet.)
