The procedure is the same as with a shape. Good info under Help, search for
hyperlinks.
Basically, create your text, either go to menu bar > insert > hyperlinks or
press cntl-K. New menu comes up, pretty much self-explanatory. Once
hyperlink is created, right click on the text and you should see new window
with your link. Click the link and it will open your word doc.
