I don't know of any specific fields tutorial, but here's an approach that
will get you a good bit of the way:
1. Open the Insert | Field dialog and click on the ? Help button. This will
open the "About fields" Help topic, which is a good starting point.
2. Look over the list of fields and note a few that look interesting to you.
3. In Word's "Type a question for help" box, type the name of the field and
the word "field" (for example, "EQ field" or "LISTNUM field"). Somewhere in
the resulting list of topics (but almost certainly not listed first) will be
the general article you want, such as "Field codes: Eq (Equation) field."
(In fact, if you use "EQ field" as your search text, you get that field
first, plus hits for a *lot* of other fields.)
4. Read these Help topics and experiment with fields you are interested in.
Part of learning to use fields is developing awareness of what fields are
behind the features you already use in Word. For example, when you insert a
page number, it is a PAGE field; if you use "Page X of Y," the Y part is a
NUMPAGES field. When you create a table of contents or index, it is a TOC or
INDEX field, and the index entries are XE fields. A date may be a DATE,
CREATEDATE, SAVEDATE, or PRINTDATE field. Understanding these fields and how
to customize them with switches will greatly increase your command of Word.
