Documentation for ActionScript classes includes syntax, usage information, and code samples for methods, properties, and event handlers and listeners that belong to a specific class in ActionScript (as opposed to global functions or properties). The classes are listed alphabetically and include classes that were new in Flash Player 8 and are found in the flash.* packages. If you are not sure to which class a certain method or property belongs, you can look it up in the Index.
