From outside userspace: This is a redirect from a page outside the user namespace to a user page (not to a user talk page). If this redirect targets a user talk page, then use {{R to talk page}} instead. This redirect page must be outside the user namespace. If this redirect is in the user namespace, then instead of the expected category, it will populate Category:Pages with templates in the wrong namespace.
From a shortcut: This is a redirect from a shortcut in any namespace to a page in any 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.
