Reserved for future use. This property is not currently supported.

Contains the character code value of the key pressed or released. The character code values are English keyboard values. For example, if you press Shift+3, charCode is # on a Japanese keyboard, just as it is on an English keyboard.

Note: When an input method editor (IME) is running, charCode does not report accurate character codes.

Indicates whether the Control key is active (true) or inactive (false).

Note: The Command key modifier on Macintosh systems must be represented using this key modifier.

The key code value of the key pressed or released.

Note: When an input method editor (IME) is running, keyCode does not report accurate key codes.

Indicates the location of the key on the keyboard. This is useful for differentiating keys that appear more than once on a keyboard. For example, you can differentiate between the left and right Shift keys by the value of this property: KeyLocation.LEFT for the left and KeyLocation.RIGHT for the right. Another example is differentiating between number keys pressed on the standard keyboard (KeyLocation.STANDARD) versus the numeric keypad (KeyLocation.NUM_PAD).

Indicates whether the Shift key modifier is active (true) or inactive (false).

Creates an Event object that contains specific information about keyboard events. Event objects are passed as parameters to event listeners.

Creates a copy of the KeyboardEvent object and sets the value of each property to match that of the original.

Returns a string that contains all the properties of the KeyboardEvent object. The string is in the following format:

[KeyboardEvent type=value bubbles=value cancelable=value ... shiftKey=value]

Instructs Flash Player to render after processing of this event completes, if the display list has been modified

Defines the value of the type property of a keyDown event object.

This event has the following properties:

Defines the value of the type property of a keyUp event object.

This event has the following properties:

1. It declares properties for later use in setting a square's background color and size.
2. It creates a new Sprite instance named child.
3. Using methods of Sprite, it draws a light-blue square that it displays on the Stage at default coordinates (0,0) by calling the addChild() method.
4. It adds two keyboard type event listeners:
• keyDown/keyDownHandler which is dispatched whenever any key is pressed. The subscriber method prints information about the event using the trace() statement.
• keyUp/keyUpHandler which is dispatched when a key is released.

In some instances, you may need to click the Stage for the keyboard events to work.
