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, both internal and external, that may have been made to the old page name.
From other capitalisation: This is a redirect from a title with another method of capitalisation. It leads to the title in accordance with the Wikipedia naming conventions for capitalisation, or it leads to a title that is associated in some way with the conventional capitalisation of this redirect title. This may help writing, searching and international language issues.
If this redirect is an incorrect capitalisation, then {{R from miscapitalisation}} should be used instead, and pages that use this link should be updated to link directly to the target. Miscapitalisations can be tagged in any namespace.
Use this rcat to tag onlymainspace redirects; when other capitalisations are in other namespaces, use {{R from modification}}instead.
From a modification: This is a redirect from a modification of the target's title or a closely related title. For example, the words may be rearranged.
In cases of modification from distinctly longer or shorter names, please use {{R from long name}} or {{R from short name}}, respectively. An abbreviation should be tagged with {{R from initialism}} or, if it can be spoken like a word such as NASA and RADAR, use {{R from acronym}}.
Use this rcat instead of {{R from other capitalisation}} and {{R from plural}} in namespaces other than mainspace for those types of modification. This may also apply to several other subcategories of modification; please check those templates' output before saving if using outside of mainspace.
