How do I replay how a doc was written?

Replay plays a Google Doc back from its first keystroke to now, the way someone reading its Version History would see it. It's in both Duey and Duey Pro, free.

To open it: with the doc open, open the Duey side panel and click Replay this doc. Replay opens in a new tab.

What you see:

• The doc's text, rebuilt revision by revision, with a play button, speed control and a slider. Skip idle time jumps over the gaps.
• Bands under the slider for each Version History entry. Google Docs starts a new entry only after 30 minutes with no edits (why).
• A summary: when writing started, the last edit, writing time, characters typed and deleted, and the number of revisions.
• How this doc was written: plain facts you can also check in the replay, such as paste-sized inserts (100 or more characters at once, marked on the slider), a long doc written in one Version History entry, no text deleted along the way, or no long pauses. There's no score.

What it needs: edit access to the doc, the same as Version History. It works on any Google Doc, typed by Duey or not.

Privacy: Replay reads the history straight from Google Docs in your browser. Nothing is uploaded to Duey.

"Replay may differ slightly from the current doc" means a few of the doc's changes couldn't be rebuilt exactly. The rest of the replay still plays.
