PowerClicks is $3
"PowerClicks is a cdev that can replace mouse click and mouse
click-holding with self-defined keyboard combinations. For example, I use
my right hand to move the mouse around, and use my left hand to press F1
for mouse click, and F2 for mouse click- holding." - Charles Hsieh
Mouse2 makes the mouse move twice as fast, so that your hand doesn't have
to move as far.
