A TextArea component can be enabled or disabled in an application. In the disabled state, it cannot receive mouse or keyboard input. When enabled, it follows the same focus, selection, and navigation rules as an ActionScript TextField object. When a TextArea instance has focus, you can control it using the following keys:
|
Key |

|
