I can only assume a Wacom tablet's driver is faking keyboard events that are bound to specific buttons. If this is the case, I don't think you'll be able to distinguish them as -pointingDeviceID, -tabletID, and friends are only valid for mouse events (which a keyboard event - faked or real - is not).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
