Wikify wisely Don't over-wikify → Redlinks → Self links → Section linking

Section headings allow for linkage directly to a specific part of an article.

For example, if you want to link to the episode "The Cave of Skulls", you can link directly to that section at An Unearthly Child. Just type: [[An Unearthly Child (TV story)#The Cave of Skulls (2)]] This is not the same as: [[An Unearthly Child (TV story)#The cave of skulls (1)]]. However, both will produce blue-links, and therefore appear to be valid links.

It's vital to capitalise the subhead precisely as it is in the article.

Additionally, the article in question must be the root article name. In other words, linking to sections through a redirect won't work. For example, if you wanted to link to the synopsis on the page The Massacre of St Bartholomew's Eve, you have to type [[The Massacre of St Bartholomew's Eve#Synopsis]]. Even though The Massacre is by far the more common name of the story, and a valid redirect exists there, the following just won't work: [[The Massacre#Synopsis]].
