One of the {TOC} switches is \x which is said to preserve a
newline character. I am formatting a long toc with TC fields and
I would like a blank line in the toc periodically.

Where in the TC does the newline character go, is it enter or
shift-enter and does the resulting empty line follow or precede
the entry that contains the newline character? I can get the
effect by entering a return manually, but this method will not
survive an update.

I did not find any definitive statements on this subject when I
searched the microsoft.public.word.* newsgroups on Google.
