Predefinição:Shortcut
This template is primarily used on Meta process and policy pages to show the shortest alias of a given page. For example, WM:DP redirects to Meta:Deletion policy. The optional parameter is typically a link to a shortcut. This behaviour is inconsistent with Wikipedia {{shortcut}}, which expects different parameter (you use WP:MOS there, instead of [[WP:MOS]] link).
For usage within other templates no parameter results in no output.
