=== Miscellaneous ===

* [[Special:BadTitleBadtitle]]: The error message shown when attempting to access a page with an invalid title or with an incorrectly linked [[Help:Interwiki linking|interwiki]] prefix. See https://en.wikipedia.org/wiki/%23 (%23 represents the number sign, which is unsupported) and https://en.wikipedia.org/wiki/meatball:WikiPedia (meatball: cannot be directly linked in the URL) for examples. Note that this special page was intentionally and by design a red link.

* [[Special:BlankPage]]: a blank page.

* [[Special:BookSources]]: search sources for a book by inputting the book's [[ISBN]] number.

Line 174:

To present the list on a page, transclude the name:

* <code><nowiki>{{Special:PrefixIndex/HMS}}</nowiki></code>

However, some pages cannot be transcluded and would produce only a wikilink (e.g., <code><nowiki>{{Special:Random}}</nowiki></code> → {{Special:Random}}). When non-existent pages are linked or transcluded, a red link is produced (e.g., [[Special:RedLinkExample]]).{{efn|[[MediaWiki:Nospecialpagetext]] is the message displayed for non-existent special pages. However, [[Special:BadTitleBadtitle]] is peculiar as it has actual viewable content but is a red link, which is because this special page was intentionally and by design to be considered non-existent (unlike all other valid page names.) See [[:phab:T262959]] for more details.}}
