THE MULTIPLE UNDO SHORTCUT

Need to back up a few steps to readjust a setting? Piece of cake. Here's a shortcut to do just that. You can step back through your History palette (found under the Window menu) by pressing Command-Option-Z (PC: Control-Alt-Z) a few times. This doesn't delete the items, but takes you back a step in the History palette each time you apply the shortcut.
