Vista – enter autotext

New PC with Vista and 2007 office suite — no time this week for “training” but have numerous docs to create, dupe, revise, etc. I always insert the path/filename at the bottom of each doc — used to be part of autotext feature under headers/footers — can’t find it now. Need help asap — 1 — where to find and 2 — how to add it to ribbon — later I’ll get to creating macros.

Thanks a million in advance
