You create a text link either using the text section or the Markdown section. But instead of linking to a website like you normally would by entering http://website.com , you put in the following link syntax show:pagelabel . The first part of the syntax page: you type just like that, and the page label is the label of the page you wish to navigate to.
You must ensure that the page label in the link syntax and your page label you have entered in the page section are exactly the same including space and upper or lower case characters as they are case sensitive.
