Question: what does command z do in photoshop?
Answer: 1. Either click "Edit" and then "Undo" in the top menu, or press "CTRL" + "Z," or "command" + "Z" on Mac, on your keyboard. 2. Photoshop allows for multiple undos, so that each time you click "Undo" or use the shortcut on your keyboard, you undo the next most recent action, stepping back through your action history.
