When used with the "Redirect category shell" (Rcat shell) template:
This page is a redirect. The following categories are used to track and monitor this redirect:
From an ambiguous sort name: This is a redirect from an ambiguous sort name to a page or list that disambiguates it. These redirects are pointed to by links that should always be disambiguated. Therefore, this template should never appear on a page that has "(disambiguation)" in its title – in that case use {{R to disambiguation page}}instead.
When appropriate, protection levels are automatically sensed, described and categorized.
Template {{Redirect category shell}} may be used to add one or more rcat templates, along with their parameters and categories, to a redirect. For more information see the documentation page below.
When used by itself:
From an ambiguous sort name: This is a redirect from an ambiguous sort name to a page or list that disambiguates it. These redirects are pointed to by links that should always be disambiguated. Therefore, this template should never appear on a page that has "(disambiguation)" in its title – in that case use {{R to disambiguation page}}instead.
If you plan to make breaking changes to this template, move it, or nominate it for deletion, please notify Twinkle's users and maintainers at Wikipedia talk:Twinkle as a courtesy, as the standard installation of Twinkle adds and removes this template. Thank you!
Please do not alter the printworthy settings of this rcat without first notifying the Version 1.0 Editorial Team, who are responsible for any and all materials, including redirects, that go into a printed version of Wikipedia.
Add this rcat to a redirect in the following manner:
#REDIRECT[[(target page name)]]{{Rcat shell|{{R from ambiguous sort name|1=(sortkey)|2=(sortkey)}}{{R printworthy}}}}
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 ambiguous sort name|1=(sortkey)|2=(sortkey)}}
Use this rcat on any redirect from an ambiguous sort name to a disambiguation page. These redirects are pointed to by links that should always be disambiguated. Therefore, this template should never appear on any page that has "(disambiguation)" in its title unless the target page also has "(disambiguation)" in its title. For those redirects use {{R to disambiguation page}}instead.
As shown above, two category sortkeys should be added whenever this rcat tags a redirect. The first parameter's sortkey is the first letter of the redirect title. For example, on the redirect Johnson, Frank the first sortkey is "J" (sortkeys are always in uppercase capital letters, please). The second parameter's sortkey is the first letter of the target article, in this case Frank Johnson, so the second sortkey is "F". Please remember to include these sortkeys. This example would appear as follows:
Johnson, Frank (page title of redirect)
#REDIRECT[[Frank Johnson]]{{Rcat shell|{{R from ambiguous sort name|J|F}}{{R printworthy}}}}
In this example, the redirect populates the following categories:
