You may deactivate category links (e.g., change [[Category:Foobar]] to [[:Category:Foobar]] by inserting a colon) to prevent the page being inappropriately added to a discussed category. You may deactivate interlanguage links (e.g., change [[it:Foobar]] to [[:it:Foobar]] by inserting a colon) when the link to a page on another language's Wikipedia is meant to appear inline rather than to serve as an interlanguage link for the page. Hiding old code samples: You may redact (replace with a note, or collapse) large code samples once discussion of the sample has ended; for instance fulfilled {{Edit fully-protected}} requests.
