Help:Self link

A self link is a wikilink which targets the page where it is placed. To avoid any confusion, a self-link is not clickable: the text is only bolded (but still represented as a  tag ).

Examples:
 * gives
 * gives abc
 * gives |abc

Utility
In templates transcluded on several pages (typically navigational templates), a link can usefully become a self link when the template is transcluded on the link target page. This avoids the reader believe they will see another page clicking it.

Clickable self links
Some kinds of self links are clickable, because they are not a simple internal link with direct target.

Full URL
If you use external link syntax, providing the full URL of the page, the link is always clickable.

E.g. gives [ abc]

Link to self redirection
If you links a page which redirects to the current page, the link remains clickable and not bolded.

With interwiki project prefix
If you prefix the target page name with local interwiki prefix (i.e. for MediaWiki.org), the link remains clickable and not bolded.

E.g. gives abc

Link to a local section
If the target contains a fragment, even if the link target the current section, it remains clickable and not bolded.

E.g. gives.

The link is a convenient way to link back to the top of a long page, without leaving the reader confused about the link's purpose.
