Based upon my XP and previous experience, you do this by:

[1] Inserting a Bookmark at the location to which you want to jump

[2] Inserting a hyperlink at the place you want to jump from.

with the cursor hovering over [2], hold the control keydown and clicking the mouse is supposed to jump you to location [1]

I say supposed to because it doesn't work for me under Vista. When I do that I get a message to the effect that: "This operation has been canceled due to restrictions in effect on this computer. Please contact your system administrator." This must be some Vista security setting that I have not been able to locate.

The process may work on your machine. It may be worth a try.
