Slides gets asked about less than Docs, and behaves the same way. Every change to a deck is recorded, the panel is three clicks away, and a pasted block of text is as visible there as it is in a document.
Yes. File, then Version history, then See version history, same as Google Docs. Revisions are grouped by time and author and you can restore or name any of them. Pasted text appears as a large change at one timestamp, in slide text boxes and speaker notes alike. Version history does not survive making a copy of the deck.
Yes, and it works identically to Google Docs version history. Open File, then Version history, then See version history. The panel opens on the right listing revisions by date and author.
You need edit access to the deck. The keyboard shortcut is the same as in Docs: Ctrl+Alt+Shift+H, or Cmd+Option+Shift+H on a Mac.
Clicking a revision shows the deck as it stood at that point. You can restore that version, or name it so it is easy to find later, both from the three-dot menu beside the revision.
Yes, and in the same shape as in Docs. A pasted paragraph appears as a revision in which a large amount of text exists that did not exist a moment earlier, with the timestamps either side seconds apart. Text typed in appears as several smaller revisions across a longer period.
Speaker notes behave no differently from slide text here. Both are recorded, and a long note arriving in one instant looks like exactly what it is.
If you want text to arrive in a deck the way typing arrives, that is covered in how to auto-type into Google Slides.
Version history is strong evidence about how a particular deck came together and weak evidence about anything beyond that. Worth knowing in both directions.
Yes. Open File, then Version history, then See version history, or press Ctrl+Alt+Shift+H. It works identically to Google Docs and requires edit access.
Yes. Revisions are listed by date and author, colour-coded by collaborator, covering text, slides added or reordered, and objects moved.
Yes. A paste appears as one revision containing a large amount of text that did not exist moments before. Typed text appears as several smaller revisions over a longer period.
Yes. Open version history, click the revision you want, and use Restore this version from the three-dot menu beside it. You can also name versions to find them later.
No. File, then Make a copy, creates a new presentation whose version history starts at that moment. The original history stays with the original deck.
