Editing Help/Categories (section)

===Sort key=== <!--T:22-->
</translate>
<translate><!--T:23--> By default, a page is sorted within a category under the first letter of its name — ''without the namespace''.</translate>
<translate><!--T:63--> Also, MediaWiki groups accented characters separately from their unaccented version, so pages starting by À, Á, Ä, will be listed under separate headings, instead of under heading A.</translate>
<translate><!--T:64--> (If you have shell access, these defaults can be changed using <tvar name=CategoryCollation></tvar>.)</translate>

<!--T:24-->
A ''sort key'' specifies under which letter heading, and where in the category list, the page will appear.

<!--T:76-->
There are two ways in which you can customise the category sortkey:
</translate>

* <translate><!--T:78--> Generically, for all categories, by adding the <tvar name=1></tvar>  magic word on the page.</translate> 
* <translate><!--T:79--> On an individual 'per category' basis, by placing the value inside the tag after a pipe character.</translate> <translate><!--T:80--> For example, the tag below will add the page under heading <tvar name=1><code>S</code></tvar>.</translate>
 <nowiki>[[</nowiki>:'''''<translate><!--T:25--> Name</translate>'''''|'''''<translate><!--T:26--> Sort</translate>''''']]

<translate><!--T:52--> Whether or not sort keys are case-sensitive depends on your configuration settings.</translate>
<translate><!--T:27--> The order of the sections within a category follows the Unicode sort order. The sort key does not change the page title displayed in the category.</translate>

Spaces and other characters are perfectly valid.
