public class Key
extends Object

The Key class is a top-level class whose methods and properties you can use without a constructor. Use the methods of the Key class to build an interface that can be controlled by a user with a standard keyboard. The properties of the Key class are constants representing the keys most commonly used to control applications, such as Arrow keys, Page Up, and Page Down.

A Flash application can only monitor keyboard events that occur within its focus. A Flash application cannot detect keyboard events in another application.

Availability: ActionScript 1.0; Flash Player 6
