Thank you very much, Ms. Mitchell,
This seems to work!
(Why couldn't I find this in Word Help where I entered "Table of Contents"
but did not get any reference at all?)
There's a help topic "about creating a table of contents" which is probably
most useful, and also "create a table of contents"--if you use the
assistant, you have to click "see more" to get to it. I would suggest
turning off the assistant (Help, use the Office Assistant) and then when you
go to help, you get a much better interface, and even if something is #6 on
the list of results, it's easier to see. That way help also retains the list
of all results and you can easily switch among them without having to redo
the search.
