The Universal Containers Administrator is editing the page layout for a new custom object when a text area field is inadvertently deleted from the page layout. What are three methods for restoring the

If the administrator has not yet saved the page layout changes, clicking the 'Undo' button or the 'Cancel' button will revert the layout to its previous state, restoring the deleted field.

Deleting a field from a page layout only removes its visibility from that layout, it does not delete the actual field definition from the object, so it won't be in the recycle bin.

The 'Fields' palette within the page layout editor displays all available fields for the object; the administrator can simply drag the inadvertently removed field back onto the layout.

Cloning a layout from another profile and using 'Save As' would create a new page layout, which would not restore the field to the specific page layout that was inadvertently edited.

If the changes were saved, deploying an older, correct version of the page layout from a sandbox environment (if one exists) can overwrite the modified layout and restore the field.
