Track Changes is a feature in Word that allows you to view changes made to a document by you or other users. Word tracks changes to both text and formatting, and you have the option to accept or reject them. These changes appear in different colors or styles to separate them from other text.
Use comments to make suggestions in a document without changing the text. Visually, they appear in balloons inside the margins. You can reply to or delete comments.
You can turn Track Changes on or off, as well as hide or unhide comments. You must turn Track Changes on to view changes to your document.
Both Track Changes and Comments are accessible with JAWS. You can review them using the keyboard.
Here is a document which explain how to use these features which was shared by Sight and Sound with TAVIP in April 2025.
