4Description: This controls if mouse clicks should be generated if the trackpoint is quickly pressed. How fast this press has to be
5 is being controlled by press_speed.
6 Values are 0 or 1.

23Description: This setting controls if the mouse click events generated by pressing the trackpoint (if press_to_select is enabled) generate
24 a left or right mouse button click.
25 Values are 0 or 1.
