From a merge: This is a redirect from a page that was merged into another page. This redirect was kept in order to preserve this page's edit history after its content was merged into the target page's content. Please do not remove the tag that generates this text (unless the need to recreate content on this page has been demonstrated) or delete this page.
For redirects with substantive page histories that did not result from page merges use {{R with history}} instead.
To a help page: This is a redirect from any page inside or outside of help namespace to a page in that namespace.
The above category link leads to a list of redirects from inside help namespace. For redirects from outside help space, see Category:Redirects to help namespace.
From a shortcut: This is a redirect from a shortcut in any namespace to a page in any namespace except template namespace.
Shortcuts are wikilinked on community pages, talk pages, and edit summaries, but not in mainspace articles.
When appropriate, protection levels are automatically sensed, described and categorized.
