This template is primarily used on Wikipedia guideline and policy pages to show the shortest alias of a given page. For example, [[WP:V]] redirects to [[Wikipedia:Verification]]
Please '''do not use''' this template on other templates, e.g. to state that the shortcut to [[Template:Foo]] is in fact <nowiki>{{Foo}}</nowiki>. There's no need to state the obvious like that, '''each''' template uses its own name as a shortcut, by default.
