Did you just recently upgrade from Office 2003 to 2010 or are you just having problems finding some obscure feature from Office 2003 in 2010?
Well, try this on for size;

It’s actually really cool, you get to select the feature in the Office 2003 gui and is shown an animation of how to find it in 2010. And as 2010 and 2007 are very alike then this may also work for Office 2007.
