# Undo & Redo

You may have made a mistake or applied an action that you come to later regret and wish to reverse. Or maybe you simply want to add something and then check how it looks on your live publication. Using the undo and redo options can solve both these issues.

The easiest way is to simply **click** the **left arrow or right arrow** at the **top right** of the **editor**. The left arrows undoes the last action and the right arrow redoes the last action.

Another method is simply **mouse over** the **options drop-down menu** in the **top right** of the **editor**. You will then see the **2 options named Undo and Redo**. Simply click undo to reverse an action you did, or redo to re-apply an action you may have undone.
