When you’re incorporating comments and suggestions, it helps to keep track of what you’ve done and what you’re still working on.
In Word 2013, you can mark a comment as done to show you’ve addressed it.
After you update the document based on a comment, right-click the comment.
Click Mark Comment Done.
Tip: To mark a reply to a comment, right-click just the reply and click Mark Comment Done.
The comment appears faded and shrinks to one line, so it’s easier to see what’s left to do.
