-===== About Links ===== 
-**Links** are the player'​s means of moving between [[passage]]s and affecting the story. They are the equivalent of being told to turn to another page in a nonlinear book; in gamebooks, for example, you do this to make decisions for the main character. But this isn't the only possible kind of link. Deena Larsen describes a whole taxonomy of links in [[http://​​fundamentals/​|Fundamentals:​ A Rhetorical Devices for Electronic Literature]]. 
-Links are marked like so:  
->​%%[[%%//​displayed text//​|//​title of passage//​%%]]%% 
-The two square brackets enclose the whole link, and the pipe symbol separates the displayed text from the passage title. ​ 
-There is also a shorter form of the link syntax... 
->​%%[[%%//​passage title//​%%]]%% 
-...where the displayed link text matches the title of the passage it links to. 
-If a story has a broken link in it, it is displayed with a red background in your story, and clicking it shows this message: 
-//The passage 'The newspaper'​ doesn'​t exist.// 
-====External links==== 
-You may also add links to external sites. These links look like this: 
-You may link to any address that a reader'​s web browser will understand. ​ 
-====Setting variables with setter-links==== 
-When you develop more complex stories that use [[variable]]s,​ it can be very useful to make certain variables be altered by the act of clicking a link. You can accomplish this by inserting an additional square bracket pair into the syntax like so: 
->​%%[[%%//​displayed text|title of passage//​%%][%%//​$variable = expression//​%%]]%% 
-The '​code'​ portion of the link syntax is treated as if it was a [[<<​set>>​]] [[macro]] - consult that page to learn about the syntax to use. A link with a piece of code attached like this is called a **setter link**, and the attached code is called its **tail**.
