Pogue takes a look at several Macro programs for both Mac and PC (a Macro program is one that allows you to assign certain actions to corresponding key strokes. Launch an app with a push of a button, have a script fire off, things of that nature). He takes Keyboard Maestro, iKey, and QuicKeys for a spin on the Mac side. They all fare well, but QuicKeys is the one the gets the highest marks, and the one that spawned the tip which has me believing in Pogue all over again. QuicKeys allows you to remap the tilde key (pictured to the right) to any button you would like. David uses it as a left hand delete button so he doesn't have to move his hand off the mouse whilst editing. Brilliant.
