Microsoft Word is a complex program that can do thousands of things.
I've dabbled with it over the years, doing small, easy things. When Word 2007 was released it had a new interface, called the Ribbon. I can't comment on whether the Ribbon is an improvement or not, but I can pass along some sites with tips to help you work with the newer versions of Word. Most of these tips work with Word 2007 and Word 2010. If something applies to only one version it's mentioned in the article.
Without further ado, here are the various tips I've gathered, in no particular order.
