Undo is typically the very first button most people learn to recognize on sight. There’s a good reason for that – we all make mistakes. Well, lucky for us, Access 2007 keeps track of everything we do so that in the event that we make a mistake, all it takes is the click of Undo button to set everything right. If you’re a keyboard fan, you can also press [CTRL] + Z.
And, if you click Undo one too many times, just click Redo to undo an undo. Both the Undo and Redo buttons can be found on the Quick Access toolbar located in the upper-left portion of your window.
