Have you ever made a mistake? I mean a mistake on the computer. You know, pasted the wrong picture into a Word document or messed up a table or a text box. The programmers of the Microsoft software (Word, Outlook, Excel, Publisher, etc.) knew we would make mistakes so they programmed in a couple of ways to “undo” them. Here are a few ways to undo your next mistake:
OPTION #1: On the menu bar select “Edit” and then “Undo.” This will eliminate the last action you took in the program. For example, if you just typed the wrong word “Edit” & “Undo” will make the word go away.
OPTION #2: There's also a keyboard shortcut to undo something you just did. Try using CTRL + Z to undo and CTRL + Y to bring something back that you undid.
If you just made lots of mistakes and want to go back and eliminate a lot of them try clicking the triangle next to the undo button to see a list of the most recent actions you have taken.
