| External link to the current page's edit page, and styled to look like an internal link | <span class="plainlinks">[http://www.mediawiki.org/w/index.php?title=Help:Links&action=edit Edit this page]</span> The plainlinks class can be used in cases where you want an external link to look like an internal one, by suppressing the icon that normally appears after it. |
