Save a named version
Open a practice copy. Open the deck menu and Version history, then save a version named ‘Before my experiment’. Version history belongs to this deck in this browser.
Check: Your named version appears in the list.
- 02
Try the change
Edit the cover heading or move an object. Use Undo for a recent edit. For the saved point, open Version history and select it to preview the earlier deck.
Check: You can compare the earlier appearance before restoring it.
- 03
Restore and download
Choose Restore to return to that version. Restoring is itself undoable. Download the HTML when you want an independent file; local browser history is not a substitute for your own saved files.
Check: The earlier heading is back, and your downloaded HTML contains it.
