I've been moving bits of text around in a document I'm doing cleanup on, and
I noticed that Word automatically inserts a space after a comma. I don't
mind that Word does this, but I like to know where and how such behavior
could be turned off if I decided I didn't like it. I looked at the various
"auto" options and tried to search in Help (on "comma"?) but couldn't find
this covered. Anyone know?

And, in a broader context, does anyone know of any reference (book, website)
that takes a philosophical/comprehensive approach to navigating the waters
of Word customization? For example, I mostly work on .docs created by other
people, I'm often unsure of whether idiosyncratic formatting/customization
is coming from local documents (strangely behaving paragraph returns, for
instance) or whether I turned something on or off several projects ago.

Thanks in advance, and sorry for being open-ended or vague in my questions.
