Track Changes is a way to keep track of the changes you make to a document. You can activate change tracking for the current document by choosing Track Changes button located on the Author toolbar. When Track Changes is enabled your modifications will be highlighted using a distinctive color. The name of the author who is currently making changes and the colors can be customized from the Review preferences page.
or by clicking theWhen hovering a change the tooltip will display information about the author and modification time.
If the selection in the Author contains track changes and you copy it the clipboard will contain the selection with all the changes accepted. This filtering will happen only if the selection is not entirely inside a tracked change.
You can associate a note or a comment to a selected area of text content. Comments can highlight virtually any content from your document, except read-only text. The difference between such comments and change tracking is that a comment can be associated to an area of text without modifying or deleting the text.
The actions for managing comments are Add Comment..., Edit Comment..., Delete Comment... and Manage Comments... and are available on the Author Comments toolbar and on the Review submenu of the contextual menu of Author editor.
Comments are persistent highlights with a colored background. The background color is customizable or can be assigned automatically by the application. This behaviour can be controlled from the Review options page.
