@persichini - I also found myself needing to disable/enable the Finger Touch feature. Recently, lvlrdka22 suggested in
this post a good way to do that. You may map a key to disable touch, and another key to enable touch, on your BT clicker. (I used Button Mapper to trigger the two intents using double-clicks.)
Separately, for the NeoReader app that works the best with Boox devices - I assume panning with keyboard is not implemented. I paired a mouse with a Boox device, and the wheels on it does not work at all - the mouse have both vertical and horizontal wheels, and neither worked.
