I need to move back and forth between places I've edited in a document. Shift + F5 is not working for returning to the previous edit. I researched this quite a bit and concluded that it is a known and unsolvable problem in Word 2013 and maybe earlier versions. It worked fine in my Word 2003.

This is an extreme inconvenience in my work. I work with documents up to 150 pages and need to easily navigate between edits. Does anyone know of a solution? Thank you.
