How to undo, redo and replay a drawing

Ctrl+Z undoes and Ctrl+Shift+Z (or Ctrl+Y) redoes. Version history (Shift+H) shows every edit as a picture you can go back to. View › Replay drawing plays the page back the way it was drawn.

On a Mac, Ctrl is Cmd.

Each action is one step: a whole chain, a ring or a clean-up undoes in one press. Both are also in the Edit menu.
