It’s not programming, but I use Karabiner to remap my Mac’s caps lock to command-opt-shift, and fn to command-alt. If I had another meta key over there I’d map it to command-shift, and be able to hit all the shortcuts I’ve assigned to menu items in Illustrator with one hand. My right hand stays on my Wacom stylus, whose two barrel buttons are set to double-click and right-click. Except when I’m in a browser, where command-click to open in new tab is much more useful than double-click.
