Thanks Balinor... I have experimented a little with "webmaster" mode. It is a useful tool for "finding" things. I also discovered page 344 of the manual. it has a nice layout of which templates are responsible for what.
I had been somewhat reluctant to dig into a 435 page document which has no side index (
Why did they do that?). It's way to big for me to print on my little inkjet printer!
One little trick I found useful while using the webmaster mode: The little pop-up window that shows the list of templates... if you click in that window and do a select-all <Ctrl-A>,then paste that into a text document... you end up with a nicely indented template structure of that page.
Tiime to roll up the sleeves and get to work!
