Template:What links here/doc

This is a documentation subpage for Template:What links here.
It contains usage information, categories and other content that is not part of the original Template page.

This template is used on many pages.

To avoid large-scale disruption and unnecessary server load, any changes to this template should first be tested in its /sandbox or /testcases subpages or in your own user subpage. The tested changes can then be added to this page in one single edit.

Please consider discussing any changes on the talk page before implementing them.

This template creates a link to the special page What links here. A particular namespace can be specified, and the link can be given a title.

Usage

For all namespaces:

{{What links here|Example||all}} → Pages that link to "Example" in all namespaces

With no title, but specifying a namespace:

With a title and a namespace:

{{What links here|Example|Titled link with a namespace|Wikipedia}} → Titled link with a namespace

Only transclusions in the Template namespace:
