In this informal YouTube segment, Paul Barnhurst highlights his favorite Excel shortcut, Ctrl+Z, explaining that it undoes recent actions. He notes that Excel imposes an undo limit of 100 steps, sharing a personal anecdote about trying to revert a mistake made long ago and being unable to do so because the limit was reached. The clip serves as a quick practical tip about the capabilities and constraints of the undo function in Excel.

The first one is favorite Excel shortcut. Ctrl+Z. And tell our audience, in case anyone doesn't know, what does Ctrl+Z do? Oops. Yeah, exactly. Undoes. Do you know how many times it will undo something before you can't do it anymore? Do I know how many times? I don't know the limit. There is a limit. 100. Okay. Sadly enough, I tried once because I screwed something up quite a while ago and I wonder if I can get back there. No luck.
