Use this rcat template on mainspace redirects only.
This redirect category (rcat) template populates Category:Redirects from symbols by default. Add this rcat to a redirect page (not a talk-page redirect) in the following manner:
#REDIRECT [[(target article title)]]
{{Rcat shell|
{{R from symbol}}
}}
Template {{Rcat shell}} is an alias for the Redirect category shell template, which may be used to add as many appropriate rcats as needed, usually from one to seven, along with their parameters, to a redirect. For more information see the documentation on its template page. This rcat may also tag a redirect individually:
#REDIRECT [[(target article title)]]
{{R from symbol}}

Some rcats automatically populate either Category:Printworthy redirects or Category:Unprintworthy redirects by default. Others, like this rcat, do not, and that means it is up to editors to choose which of those categories, Printworthy or Unprintworthy, is appropriate and should be populated. The rcats that are used separately to populate those categories are:
