I want to set up a template for users that will display instructions when
they go to specific areas of the document.  For example, when they begin to
enter text in the area labeled Summary, I want to display information on what
should be included in the Summary.

I'm uncertain of the best way to go about doing this. I'm considering
setting it up as a form and have a macro execute which displays a dialog box
containing the instructions when they click on a specific area of the
document, such as the Summary.  

Another idea I have is to just create a custom toolbar with buttons they can
manually click to retrieve the instructions on particular areas of the
document.

Anybody have any suggestions?
