Tips
If you accidentally delete a slide, immediately choose Edit > Undo, or press .
Another way to roll back to an earlier version of your Keynote file is to choose File > Revert to Saved, which will restore the last saved version of your file.
If you delete the first slide in a group of slides (see "Grouping Slides" later in this chapter), all the slides indented below it will also be deleted. Be careful!
