There would be no easy way to do this. Document 2 has the hyperlink, and the display text is set. How would Document 2 know that Document 1 has changed?
"Link" is a little bit of a misnomer. Activating Pointer is more accurate. There is no "link" really, in that there is no flow of information.
Again, how would Doc 2 know that Doc 1 changed?
If your links were well designed, using bookmarks, then it COULD be possible - with some fancy coding - to check and update this kind of thing. In Doc 2 you would have to:
1. Put the display text of the hyperlink into a variable
2. Pick up Address of hyperlink
3. Parse out the path and filename into a variable
4. Parse out the bookmark name into a variable
5. OPEN that file (Doc 1)
6. pick up the text of the bookmark
7. compare the display text and the bookmark text
8. if different, copy the current text to a variable
9. close Doc 1
10. if different, edit the hyperlink and change the display text to variable you got from Doc 1.
Is this do-able? Yes. Is it worth it? Maybe. How critical is this? There are some issues with how Word stores hyperlink addresses that would need to be worked out. Unless this was REALLY worth the effort...it seems like a lot of work to achieve this.
