All the Office programs let you click on undo to go back to the previous step if you have made a mistake. If you have you wondered how far back you can go then here's the answer:
Outlook - unlimited undos
Word - unlimited undos
Access – 1 undo
Excel – 16 undos
PowerPoint - 150 undos
Publisher - 20 undos
FrontPage - 30 undos
You can change the number of undos in Access and Excel by editing the registry. We don’t recocommend this though.
PowerPoint is set to 20 undos by default but you can change it if you like. It is not recommended that you increase it too much because it may cause problems in PowerPoint. Go to Tools, Options, Edit tab, and from there you can change the Maximum number of undos up to 150.
