Undo reverses your last action
⌘Z (Mac) or Ctrl+Z (Windows) steps back through your recent edits — one press per action. Most apps keep a long undo history, so you can press it repeatedly to walk back through many changes.
Redo brings it back
Changed your mind? Redo with ⌘⇧Z on Mac. On Windows most apps use Ctrl+Y, though some (Office, browsers) also accept Ctrl+Shift+Z. Redo only works until you make a new edit.
