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.
From a subtopic: This is a redirect from a subtopic of the target article.
To an article without mention: This is a redirect to an article without any mention of the redirected word or phrase.
For titles that are obvious omissions from target articles, check the rcat index for more specific templates to use instead of this rcat – examples: ((R from misspelling)) for misspellings of article titles or ((R from incorrect name)) for wrong names.
