Operating the mouse with your foot
Yes ladies and gentlemen, I am now operating my mouse with my foot. I'm using a freeware program called MouseTool (mentioned in my previous post) to automatically click whenever the mouse stops moving (it also has a way to let you drag, and there are buttons for making the next click a right-click or double-click). Now I never have to take my hands off the keyboard. MWA HA HA HA.
The Firefox Mouse Gestures extension is handy for opening a link in a new tab when you drag up (or in a new window when you drag down).
Note that you'll need to crank down your mouse sensitivity for this to be comfortable.
