Special pages filter
FilterSpecialPages enables easy filtering of the list of special pages.
The functionality provided by this extension can be found on Special:SpecialPages.
It adds a search box at the top of the page. Typing in this field provides search-as-you-type functionality, and will refine the list of special pages to match the search term.
Clicking Enter when there is only one page in the search results opens the target page.
Clicking the Esc button highlights the text in the search field so it can be replaced easily.
FilterSpecialPages is an extension for MediaWiki. BlueSpice is not required. FilterSpecialPages can be used with the Vector skin, too.
