How to Use the Undo and Redo Commands


The "Undo" and "Redo" commands are relatively universal throughout most platforms and programs, and are quick, easy ways to help users fix mistakes or alter any changes they made to a document or in an application. Once you learn these simple commands, they will eventually become second nature.

Step 1

Review the "Help" files of whatever application you are using to make sure that the "Undo" and "Redo" commands are available within that application. Most standardized applications like web browsers, word processors and graphic editing programs have this feature, but it's always best to check, especially if you've had difficulty with correcting mistakes in the past.

Step 2

Recognize your mistakes quickly. Some programs only offer one-step undo commands, which means that it will only correct the very last alteration you made to a document. If you make multiple mistakes and don't catch it until you've changed something several times, the program may only correct the last instance of that mistake.

Step 3

Hold the "Control" key, and then press the "Z" key to undo the action if you use a PC Windows platform.

Step 4

Hold the "Apple" key, called the "Command" key, and then press the letter "Z" key to undo any mistakes if you use a Macintosh operating system.

Step 5

Repeat the process multiple times to undo several mistakes in a row, starting with the most recent.

Step 6

Redo an action that you have undone by holding down the "Control" key and pressing the "Y" key.

Step 7

Press and hold the "Command" key, and then press the "Y" key to redo an action if you are using a Mac platform.

Tips & Warnings

  • If you are use a program that is limited to one undo function, then you will wind up redoing an action that you had previously undone if you press the "Undo" command more than once. You must alter the document again between undo commands in order for the program to reset and offer you another undo option. Otherwise, you'll simply go back and forth with the exact same mistake you tried to fix the first time.
  • Make sure anything you undo is what you really wanted in the document before you do anything else to change the document. Once an action is undone, altering the document will then reset the undo commands, making it difficult to recover whatever it was you undid.
