How do I undo actions in a portal?

To undo actions in text areas of your portal, click the undo button. 

For some actions like deleting sections and changing banner color, you'll see a notification display in the corner of your portal and you can click Undo. Only one action can be undone.

Note that if you click the X to close the message, the action cannot be undone.
