It might also be helpful to add more comments to input.h or add something to the Documents directory. My current understanding: BTN_TOOL_FINGER: touch pad single finger BTN_TOOL_(DOUBLE|TRIPLE|QUAD)TAP: touch pad 2,3 and 4 fingers BTN_TOUCH: touch screen single finger BTN_[0-N]: not really for fingers. Are the taps at all appropriate for touch screens? How should the wacom non-screen tablets be treated, should they act like touch pads both for absolute and relative modes? Should there be any difference between pad and screen devices with respect to multitouch events (currently, I'm assuming not)?
