Occasionally, you might make a change to the page that is unintentional or gives you an unintended or undesirable result. For these circumstances, you can use the Undo and Redo buttons up to 5 times.

Undo will revert the last change on the page. Redo will reverse the effect of the Undo.

The Undo and Redo buttons can be found on the top of the screen.
