It is true that slot control is MT related, but I am looking at this from the perspective of future expansions like KEY_MT, KEY_REL, and such, finding a way to signal to user space which events are handled via slots. If we had ABS_MT_SLOT, we would most likely get applications which store ABS_MT_SLOT as an attribute of the slot together with ABS_MT_POSITION_X, ABS_MT_TOUCH_MAJOR, etc, which is just not right. So the proposal is ABS_SLOT. May we have your verdict, please. :-) Henrik
