Did you delete something on a page and want to get it back? Use the undo button!

The Undo button is located on the top toolbar in the EDONext page designer, and the Redo button is right next to it.

Clicking on the Undo button will reverse any edits you made on your page. Clicking the Redo button will allow you to recreate the last action that was undone.
 

On Keyboard:
