Unpatrolled edits will display a ! on Special:Recentchanges. To patrol an edit, usually you'll need to click (diff) and, after reviewing the edit, click [Mark as patrolled]. This will apply only to that specific edit. For newly created articles, [Mark this article as patrolled] will appear on the page itself.
This feature is available only to users who are in the junior administrator usergroup, or a higher usergroup.
