Patterns you can use in a "passage" (n.b. very much like 'markdown' syntax)
[[xxxx]][[a link to some topic]] generates a clickable link or hyperlink matching the preamble to the Twine "passage" of the same title (a link to some topic), or assume you wish to create a new passage with that text as the title name.
[[ xxxxx|xx]][[a link to a topic when you click on this text |the new topic title]] will hyperlink the preamble text to a Twine "passage" titled "the new topic title", or assume you wish to create a new passage with that title name.
Some examples from the Twine guide showing how this pattern has been extended...
The arrow indicates where (which passage) the clickable text links to.
[[Open the cage door->Devoured by Lions]]
[[Devoured by Lions<-Open the cage door]]
Introduce a random element to the narrative (sticking with built-in story format "Harlowe")
The referee reveals that the coin is (either:"heads","tails").
Use HTML markup to include images i.e.:
<img src="the URL of your image" width="500" height="300" alt="Two foxes">
