following:
In the Window group on the View tab, click View Side by Side to see two
different documents
Click New Window before clicking View Side by Side to see the same
document in two different windows
In the Window group, do any of the following:
If you want to scroll through the documents (or different windows containing
the same document) at the same time, click Synchronous Scrolling
If you want to reset the document windows to the positions they were in when
you first started comparing documents, click the Reset Window Position
