The colon trick is a method of providing a link to a category, image or interwiki link without adding the page to the category, displaying the image or adding the interwiki link to the interlanguage links. It also allows for linking to pages with titles beginning with a recognized external link prefix, such as http:// or //Hus.By adding a colon just inside the opening double square brackets of the link, the default behaviour of the MediaWiki software will be bypassed. It will appear as a conventional wikilink.A colon can also be used to transclude a page in mainspace, rather than template space. For example, {{The Beatles}} will transclude Template:The Beatles, but {{:The Beatles}} will transclude the mainspace article The Beatles. This is useful when the mainspace article has been specially formatted to be transcluded in other articles, by using <noinclude> or <includeonly> tags to indicate the portion that should be included when the article is transcluded.
