Three pedals are preprogrammed for mouse button actions. The X-keys mouse click foot pedal offers all the same capabilities as our standard X-keys USB foot pedal. The user can rest a foot on the main pedal without activating it and click with just slight additional pressure from the toe or ankle. The outside pedals' rear provides instant additional functions easily reached to the left or right of the main pedal.
