In Excel, if you copy a cell into another cell, you've also changed it,  
usually; I like layered undo in that situation. Excel is a much easier  
environment in which to PROVIDE multiple undo, too.

Overall, though, I agree with Andrzej that good work habits are the best  
protection against errors.
