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 that may have been made, both internally and externally, to the old article title. This template automatically tags any redirect that results from a page move.Template:From incorrect name
From a template shortcut: This is a redirect from a template shortcut in any namespace to a page in template namespace.
If target page is not a template, then use Template:R from shortcut instead. Template shortcuts are wikilinked on community pages, talk pages and edit summaries, but not in mainspace articles.
Note:Template talk pages are in a talk namespace; they are not in the template namespace. All shortcuts to talk pages should be tagged with {{R from shortcut}}.
