The Undo tool within the Text Editor allows you to undo or reverse your last action. You can undo more than one action. The Redo tool within the Text Editor allows you to reverse your last Undo action. This means that you can reverse more than one action that has been undone. You can only use the Redo tool after the Undo tool has been used.
This can be helpful if you have accidentally deleted something or have added something in error. Please note that you can only use these tools while you are in the Text Editor and before you have saved your changes.
