I was just playing with iTunes and hit some random keys while visual effects were on (as you do.) And the keys did stuff! Now I might be a bit slow on this, but, chances are, there are others out there who didn't know about this. So here's a list of what the keys do when visual effects are on: H or ?: help F: show/hide frame rate T: toggle frame rate capping B: show Apple I: track info Q or W: change pattern A or S: change shape Z or X: change colour N: toggle high contrast colours R: random config C: current config M: freeze config D: defaults Cool, eh?
