iTunes’ built-in visualizer has been improved and changed many times over the years, but one thing that’s been constant in recent versions is a series of undocumented keyboard shortcuts for controlling it once the action’s started. While you can see a brief rundown by hitting the /? key, here’s a quick list: Tap M to change the current mode, P to change the palette, I to display track info, C to toggle auto-cycle on and off—it’s on by default—F to toggle freeze mode, N to toggle the mysterious “nebula” mode, and L to toggle the camera lock on and off. Now there’s no excuse for staring at a particularly nauseating color combo for longer than it take to tap a key.
