Oh poor Office 2007: Wherefore art thou undo?
Looking for undo & redo in the new Office 2007 ribbon?
It ain’t in the ribbon, it is in the quick access toolbar. But hey didn’t the ribbon replace toolbars!

Ctrl-Z works fine - thankfully they didn’t change this.

Good one - we all know that short cut Ctrl-Z for Undo, but what is it for Redo ??? this one we forget (by the way: it is Ctrl-Y)
