From an ambiguous term: This is a redirect from an ambiguous page 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.
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.
