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 page name)]]
{{R from incomplete name}}
This is in accord with instructions found at WP:REDCAT.
Use this rcat to tag any redirect in any namespace that is titled with an incomplete name. It targets a page that is titled with the complete name of the subject. If the redirect is a short name, not an incorrect, incomplete name, for example, Elvis for Elvis Presley, then use {{R from short name}} instead. Examples of incomplete names are:
