通过重写keyDownHandler()方法实现。

comps/MyAccordion.as   ：

/**

 */
package comps {
    import mx.containers.Accordion;
    import flash.events.KeyboardEvent;

    public class MyAccordion extends Accordion {
        public function MyAccordion() {
            super();
        }

        override protected function keyDownHandler(evt:KeyboardEvent):void {
        }
    }
}
