Motion may not work for laptop trackpads. Timeouts may not be a great
solution if the value is set too high. Set a low timeout and also use
a motion hysteresis:
Below a certain motion level, within the timeout period ==> click
Above a certain motion level, within the timeout period ==> scroll
Below a certain motion level, outside the timeout period ==> scroll
Above a certain motion level, outside the timeout period ==> scroll
This might work. It needs experimentation. In particular, a low timeout
value is going to lead to scrolling when mouse click was the intended
behaviour.
This allows the motion variable to dominate. It's equally possible to
let the timer dominate, in which case, change the scroll in the second
combination above to a click. This would allow even a mouse in constant
motion to be able to click ..
