A couple of years ago I created an automatic TOC in Word 2010. I've since upgraded to 2013, and I am now working on that document in the new version. I frankly have no recollection of how I created that TOC in the first place, and I am now faced with the problem of having to change just one page number in it. Can this be done, or do I have to re-create the entire TOC.

Thanks for any guidance.
