+To add a new shortcut, use the `shortcut`
+[[ikiwiki/PreprocessorDirective]]. In the url, "%s" is replaced with the
+text passed to the named shortcut, after url-encoding it, and '%S' is
+replaced with the raw, non-encoded text. The optional `desc` parameter
+controls the description of the link.
+
+Remember that the `name` you give the shortcut will become a new
+[[ikiwiki/PreprocessorDirective]]. Avoid using a `name` that conflicts
+with an existing directive.
