 The <<.op cycle>> operator requires at least one parameter.
 
 ```
-[toggle[<titles>],[step-size]]
+[cycle[<titles>],[step-size]]
 ```
 * ''titles'' : a title list to toggle in the input list cyclically. If no title from the parameter is present in the input, the first title is added. If a title from the parameter is present in the input, it is replaced with the next title from the parameter. Note that all titles specified in this parameter should be unique.
 * ''step-size'': (optional). Defaults to 1. Specifies the number of steps in the parameter list to move each time. Can be a negative number.
