Excellent resource on line for the Ribbon
 

If anyone needs a superb step-by-step manual on how to learn about
customizing the Ribbon in Excel 2007, I would very highly recommend Nick
Hodge's most outstanding web site at:

His crystal clear examples opened up this new world to me and summarily
ended weeks of frustration! Thanks Nick!
