From the wiki page View history link, you can view any saved revision or revert to it. Reverting to it will create another revision of the page.
You can't revert to one of the two pages while you're viewing a comparison of them.
- On the wiki Table of contents, click the page you want to check.
- Click History. The revision list appears.
- Click the link for the revision you want to view. The revision page appears, with links at the top to view the current version or revert to this version.
- Click Revert to this version. The page version you're viewing becomes the current version, and the version you reverted from becomes a previous version.
