Multiple Undos in Camera Raw
QuickTips
If you press Command-Z (Windows: Ctrl-Z) it only undoes (or redoes) your last step by if you want real multiple undos (where you can undo step after step after step), then you’d press Option-Command-Z (Windows: Alt-Ctrl-Z). Each time you press that keyboard combination, it undoes another step, and keeps undoing (it’s not limited to just 20 undos like Photoshop’s History panel does by default).
