MS Access utilizes an "on change event" to fire off some VBA code every time
specific object text is changed.  

I have a Word VBA Macro which copies field information to various places
within my word document.  I would like this macro to run whenever a user
makes a change to the field information of specific cells, similarly to how
the Access "On Change event" works.

How can this be done?  All ideas are welcomed.

Thanks,

Jim in MD
