I've never authored a book - well, sort-of yes, but not with such an index.
 So I don't know what's so difficult about it or how you're using it.

I'm not asking for an explanation here as I won't be an author anytime soon!

But I can imagine Steve writing a how-to for troubleshooters.com  My
imagination is wild and badly mannered - sorry about that!  :-)
