From a page move: This is a redirect from a page that has been moved (renamed). This page was kept as a redirect to avoid breaking links, both internal and external, that may have been made to the old page name.
From a stylization: This is a redirect from a stylized article title. It leads to the target in accordance with Wikipedia naming conventions for symbols and stylizations. This may help writing, searching, and international language issues.
Use this rcat to tag only mainspace redirects; when stylized titles are in other namespaces, use {{R from modification}} instead.
From numeral(s): This is a redirect from a title that includes the mathematical symbol of a number (or numbers) to an article with the word form of the number, or any other name of the number.
Mentioned in a hatnote: This is a redirect from a title that is mentioned in a hatnote at the redirect target. The mention is usually atop the target article. It may, however, be directly under a section header, or in another article's hatnote (whenever the hatnote is under a section, {{R to section}} should also be used).
The titles of redirects mentioned in hatnotes may refer to a subject other than that of the target page. It is possible that this redirect may need to be retargeted, or become an article under its own title (see {{R with possibilities}}). If the title is a good candidate for a Wiktionary link, it may also be added.
