Daedalus,
I've just changed to Word 2007. First impressions are that it's different. Can't figure out yet how to do the Change Case trick, which was simple enough in the previous version.
If I remember correctly, which may not be the case, you highlight the relevant section, then click on Format - Change case. It gives you various options, most of which are reasonably self-explanatory.
Reasonably simple, honest.
