First I removed the default Word custom.dic file and created my own (jfaughnan.dic) file in a folder I backup and control. So no more lost dictionary when I change machines. I then created a Google Apps document  to hold a copy of the dictionary. I will periodically merge  that with my other application specific dictionaries -- which are particularly important on handheld devices . Imperfect, but good enough.
Then I finally paid attention to the Word settings for "smart"  Edit and cut/paste, turning off most of the default behaviors.
So I recommend the book (though it doesn't include Word 2007), but I don't agree with their recommendation to use Styles for everything. That's what every book on Word says, and they're all wrong. Styles are too broken to seriously contemplate unless you're a technical writer  .
 Incredibly annoying pink color scheme today. I wish Google spent less time being cute and more time fixing their #@$!$ buggy products (such as their custom search widget, which is broken as of this morning).
 Ironically Google Docs has its OWN dictionary, so the text file shows a spelling error indicator for every entry! There's no way to edit that dictionary. One day perhaps.
 In the long forgotten glory days Palm had a great auto-complete tool with a custom dictionary. Emily's BlackBerry has one too - very important for word completion.
 Copy/paste to TextPad, sort and delete dupes, copy/paste back.

 Most of them hate Word even more than I do.
 Word 2007 includes a complete do-over of Styles but it requires a (funny that) new file format that's incompatible with everything in the megaverse.
