How to add a popup hyperlink (small text box) in a word Doc

[John Davy]

Hi

I am writing a training document and have some terms in the text that may
need defining. I would like to have a small popup window with the definition
of th term that is hyperlinked.

If you already have a hyperlink to the term, you can add some brief text as
the "ScreenTip" for the hyperlink.
