Undo the Last Operation
 
The Undo command undoes anything you do in PowerPoint, such as formatting text, typing and deleting text, formatting - all of it. You can allow running free the Undo command in two helpful ways:
 
One way is Press Ctrl+Z.
 
You can also access Undo option by Click the Undo command button on the Quick Access Toolbar.
 
An advantage of using the Undo command button is that it sports a drop-down menu that helps you evaluate the past several things you've done, or that can be undone.
 
. Unfortunately, you cannot pick and choose from the Undo command button's drop-down menu; the menu simply allows you to undo multiple instances of things all at one time.

. At periodic times, Undo doesn't work. PowerPoint warns you, though.

. The Undo command doesn't work when there's nothing to undo, or if something simply cannot be undone.
