Editing Help:Diff (section)

=== Internal links ===
Although external links are easy to copy and paste, they can be long and unwieldy. Diffs can be wikilinked using <nowiki>[[</nowiki>Special:Diff/<var><code>diff</code></var><nowiki>]]</nowiki> (e.g. [[Special:Diff/123456789]]) or <nowiki>[[</nowiki>Special:Diff/<var><code>oldid</code></var>/<var><code>diff</code></var><nowiki>]]</nowiki> (e.g. [[Special:Diff/100000001/123456789]]) where you should replace <var><code>oldid</code></var> and <var><code>diff</code></var> with appropriate values seen in the URL. This syntax is easy and can even be used in [[WP:EDSUM|edit summaries]].
