track changes
The Track Changes feature is turned on.
In order for Word to indicate that changes have been made in a document, you must have the Track Changes feature enabled. The three ways in which it indicates that changes have been made are through colored underlines, a bar in the margin and the presence of notes in the extended margin.
Open the Tools menu, click Options, and then select the Track Changes tab.

It allows a user to show the changes they have made, like deleting or editing text. It is particularly useful when more than one person is working on the same document. People can see their own changes and changes made by others and they can choose to revert the changes or to keep them.
Well, if you have track changes on, then it can indicate by color, by a bar in the margin, and by actual notes in an extended margin (if you turn it on... otherwise down at the botton in a notes area) showing what was changed. If you don't have track changes on, you could still compare two documents (new and old) to see what changed by doing a merge... then it will mark up the document as though it had track changes on. It will be a little messier though, especially if you are using automatically updated fields... those will all appear as changes.

When more than one person is working on a document it enables people to know what changes have been made and who made them. It also allows you to reverse the changes. Even if one person is using it, it can be useful to track changes.
