Demonstration of reverting edits using rollback

 * 1) Add two or more edits to the page by clicking [ here].
 * 2) Go to the [ history page].
 * 3) Click on the blue-linked "rollback" ( rollback | undo ) at the right-hand side of the last edit string.
 * 4) This will roll back the page to the version prior to your edits.
 * 5) To see the difference between rollback and the undo tool, go back to the page history and click "undo" instead of rollback.
