If you make a mistake or apply an action or an adjustment you do not like, it can be undone in most cases. This option is not available from the individual tools but from the main menu or a toolbar instead.
- Select the image or images in the Browser.
- Choose Edit -> Undo or press Cmd+Z/Ctrl+Z (macOS/Windows) or press the Undo icon (left-facing curved arrow in the toolbar). Continue with this command to undo all previous adjustments or actions.
- The Redo icon (right-facing curved arrow) will become active as soon as the Undo icon is pressed. Alternatively, choose Edit -> Redo, or press Shift+Cmd+Z/Ctrl+Y (macOS/Windows).
