Changes to the document (diffs), messages, and comments show up in the thread on the left of every document. You can think of this thread as the "News Feed" of the document -- showing you the entire history chronologically if you scroll to the top of the thread.
Whenever a change is made to the document, it shows up in the thread. You can see who made the change, when they made it, and what device they used.
Changes are tracked differently:
- Text that has been deleted is highlighted in red with a line through the text.
- If a block of text contains both deletions and insertions, the inserted text is highlighted in green and underlined.
- If a block of text contains only insertions, the inserted text is underlined in green.
- When large sections of text have been removed, the text is grayed out.
If there have been multiple changes, there will be a stack of diffs. Click on the snippet to reveal the full set of changes made by a person at a particular time.
