The ‘change tracking’ facility in MS Word record changes among different versions of a document.

You can access these by using the menu combination View | Toolbars | Reviewing (Word 2003) or the Review tab (Word 2007) to bring up the change tracking toolbar and then by clicking its “Track Changes” button. You can also choose Tools | Track Changes to track changes (without having the tool bar available, in Word 2003) or, finally, you can press Ctrl-Shift-E to toggle change tracking on and off. Note: make sure you are in the ‘print layout’ view so that comments and deletions appear in the document (View | Print Layout).

Three kinds of changes are possible:

1) Deleted text – is indicated by the text being moved to ‘balloons’ in the right hand margin and denoted as “Deleted”

2) Inserted text – is denoted by being underlined and presented in color different from the text

3) Comments – are indicated by a balloon in the right hand margin and denoted as a “Comment”. The text to which the comment is oriented is surrounded by parentheses.

Note: Make sure that the Store random number to improve merge accuracy check box is selected on the Security tab of the Options dialog box (click Options on the Tools menu)
