Notes

• The redirect will automatically be tagged with {{R from television episode}}, {{R from fictional character}}, {{R from fictional element}}, {{R from fictional location}} or {{R from song}} depending on the type of redirect, and be placed in the relevant category.
• Using the series parameters will place the redirect in a series-specific category: [[Category:(series) (object) redirects to lists]], such as Category:Arrow (TV series) character redirects to lists.
• If the redirect does not use one of the following correct disambiguation — (series), (series) episode, (series) character, (series) element or (series) character — the redirect will be tagged with {{R from incorrect disambiguation}} and {{R unprintworthy}}.
• If the redirect is using one of the unprintworthy templates, it will be categorized as {{R unprintworthy}}. If not, it will be categorized as {{R printworthy}}.
• If the redirect is using one of the templates marked above as not {{R with possibilities}}, it won't be categorized with it.
• For episode redirects, a short description will be added only to the primary redirect. Additionally, If |series_name2= (or higher) is used, a short description won't be added.
