I've been using Adobe Acrobat Reader since version 4. While I am reading a PDF document, I can use the Back/Forward buttons to navigate between the previously browsed pages.
For example, I am on page 6 in Acrobat Reader, and I click a cross-referenced link to page 70; I can go BACK to page 6 by hitting the back button.
Is there any such functionality available in Microsoft Word 2003/2007? There has to be something like it, but I am unable to find it.
