From a page move: This is a redirect from a page that has been moved (renamed) or is the result of a page move. One reason this page was kept as a redirect is to avoid breaking links, both internal and external, that may have been made to the old page name. Any redirect with a page move logged on its history page should be tagged with this rcat template.
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.
Please note that there are many more specific templates. Please use {{R from alternative spelling}} for spelling changes (including punctuation and spacing); see subcategories of Category:Redirects from modifications for other options (capitals, abbreviations, diacritics, plurals, stylizations, transliteration, ligatures, different parts of speech, etc.). If you are unsure which to use, this template is fine; someone will make it more specific later if necessary.
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.
When appropriate, protection levels are automatically sensed, described and categorized.
