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 an alternative name: This is a redirect from a title that is another name or identity such as an alter ego, a nickname, or a synonym of the target, or of a name associated with the target.
This redirect leads to the title in accordance with the naming conventions for common names to aid searches and writing. It is not necessary to replace these redirected links with a piped link.
If this redirect is an incorrect name for the target, then {{R from incorrect name}} should be used instead.
To a section: This is a redirect from a topic that does not have its own page to a section of a page on the subject. For redirects to embedded anchors on a page, use {{R to anchor}} instead.
