Wikipedia:Tip of the day/May 6, 2006
Sometimes it is necessary to refer to a section of a page when linking, rather than the whole page. You can create a link to any subheading on any page in Wikipedia by including a # followed by the subheading at the end of a link. For example: Wikipedia:Community Portal#Things to do. In all section links, be sure to use a piped link for readability. Using a piped link, the previous example looks like this: Things to do. If a section title changes, rather than go red/inactive, the link will lead to the top of the linked page. Keep in mind that redirects do not follow section links, making it useless to include them there.
