From other capitalisation: This is a redirect from a title with another method of capitalisation. It leads to the title in accordance with the Wikipedia naming conventions for capitalisation, or it leads to a title that is associated in some way with the conventional capitalisation of this redirect title. This may help writing, searching and international language issues.
If this redirect is an incorrect capitalisation, then {{R from miscapitalisation}} should be used instead, and pages that use this link should be updated to link directly to the target. Miscapitalisations can be tagged in any namespace.
Use this rcat to tag onlymainspace redirects; when other capitalisations are in other namespaces, use {{R from modification}}instead.
To a disambiguation page: This is a redirect to a disambiguation page. This redirect is intended for use in links from other articles that need to refer to the disambiguation page, rather than be disambiguated. Therefore, this template should only appear on a redirect page that has "(disambiguation)" at the end of its title. Ambiguous titles that do not have page names ending with "(disambiguation)" should use {{R from ambiguous term}} instead. For disambiguations that later prove to still be ambiguous (e.g. "(painter)" when there are multiple notable painters by the same name) and which redirect to disambiguation pages, then {{R from incomplete disambiguation}} is the appropriate rcat template.
