The important thing to remember is that AutoFormat is different from
AutoFormat As You Type. The former can be both helpful and infuriating
(depending on your settings), but both can be configured pretty
specifically. For example, if you want to use AutoFormat *just* to convert
email addresses and URLs in a document into clickable links, you can check
just that box in AutoFormat, clearing all the others, and run it over the
text.
You can definitely add a toolbar button for this. I honestly think it used
to be on the Formatting toolbar by default, but apparently it isn't in Word
2003 and is not even offered as one of the easy "Add Buttons" options, but
you can certainly add it using Tools | Customize, and I see from the "Add or
Remove Buttons" list that it has a built-in keyboard shortcut of Alt+Ctrl+K
(which I didn't know).
In its default configuration, AutoFormat does a surprisingly good job with
raw text that has had direct formatting applied (the sort you get from
someone who doesn't know how to use Word). You'll find that many "headings"
have been created out of single-line paragraphs, but it's pretty easy to
reverse the mistakes, and the cost/benefit ratio is satisfactory IMO.
