Delete Smarttag Term in Word

I've defined a Smarttag for the Word "address". When I now click on the Smarttag and run an action I want to delete the typed word "address" and insert some other words.

Can somebody help me?
The Smarttag works, but I don't know how to delete the typed word.

Thank you,
Tom
