Do you “undo” a lot in MS PowerPoint?
Ever run out of undo steps and wish for more?
If your response was yes, here’s what you need to know about PowerPoint to get a few (or a lot) more undo steps added to your list.
Use the Office Button / File tab of the Ribbon, PowerPoint Options button, to get to the Options dialog box.

We need the Advanced category of options, Editing section.

Set a value between 3 and 150 in the Maximum number of undos: field.
Click OK.
That’s it. You now have the power to undo more steps than you can probably even remember!
And… as a special bonus, you can use this technique in other MS Office programs to increase the number of available undos… one trick, many places of application.
