From a shortcut: This is a redirect from a shortcut in any namespace to a page in any namespace except template namespace.
If target page is a template, then use {{R from template shortcut}} instead. 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}}.
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.
