interwiki

This filter provides a simplified, wiki-like syntax for linking to articles or search results on many commonly-used internet reference websites.

For example, [[w:public relations]] can create a hyperlink to the Wikipedia encyclopedia article on public relations; [[dict:public relations]] links to a dictionary definition of the term; and [[google:public relations]] links to a Google search on the phrase. The module also enables easy linking to a thesaurus and eBay, and additional resources can be custom-added as desired. It uses the same "interwiki" table as the MediaWiki software that powers Wikipedia, dKosopedia, and a number of other popular wikis.
