__FORCETOC__  Usage This template provides for a uniform header for use on all redirect categories. Its parameters allow modifications of the template's default output so that each header can be customized for the specific redirect category where it is being used. To use, copy the following syntax and paste it atop the redirect category intended for its use:   Use  and (or)  to describe the purpose of the redirects in the category.  The  parameter names the  template in redirect categories.  Use  to list the associated redirect template (rcat) used with the Redirect category shell template, along with its parameters.  For , add  for the header to include an instruction to use {{DEFAULTSORT:}} in cases where appropriate.  Unused parameters may be removed or left, blank, in place; both conditions result in the template's rendering of the default output where each modification would otherwise occur.    Examples   With the syntax unaltered, (left blank), as copied above; ie: {{Redirect category|from=|to=|template=|parameters=|sortkey=}}  The default output produces:  When  is used; for example, as:  {{Redirect category|from=a subject that does not exist as a standalone article|to=|template=|parameters=|sortkey=}}  It produces:  Continuing the example, if  is also used; like shown:  {{Redirect category|from=a subject that does not exist as a standalone article|to=an  article, or subsection thereof, where the subject could be described, but presently is not|template=|parameters=|sortkey=}}  It produces:  When  is used; for example:  {{Redirect category|from=a subject that does not exist as a standalone article|to=an  article, or subsection thereof, where the subject could be described, but presently is not|template=Rcat shell|parameters=|sortkey=}}  It produces:  And with the specific  used in ; for example:  {{Redirect category|from=a subject that does not exist as a standalone article|to=an  article, or subsection thereof, where the subject could be described, but presently is not|template=Rcat shell|parameters={{tl|R to article without mention}}|sortkey=}}  It produces:  And if  is set to "yes"; for example:  {{Redirect category|from=a subject that does not exist as a standalone article|to=an  article, or subsection thereof, where the subject could be described, but presently is not|template=Rcat shell|parameters={{tl|R to article without mention}}|sortkey=yes}}  It produces:   Adding a shortcut   One shortcut can be installed within the lower maintenance banner; for example: {{Redirect category|from=a subject that does not exist as a standalone article|to=an  article, or subsection thereof, where the subject could be described, but presently is not|template=Rcat shell|parameters={{tl|R to article without mention}}|sortkey=yes|shortcut=CAT:RAW}}  It produces:   Categorisation   This template adds categories to :Category:All redirect categories, :Category:Hidden categories and :Category:Redirect tracking categories. If the template is transcluded on a page outside of the category namespace, then that page will not be added to these categories and will be added to  instead.   Language categorisation   This template is also used within two templates that are found on language category pages.  When a language category is created, one of the following two templates (depending on whether the category is for "from" or "to" language redirects) should be used to provide useful information about the new category:     These two templates will also automatically categorize the page into the correct parent category.  See the edit page for  for an example of template usage.   See also    Wikipedia:Template messages/Redirect pages
