Removing keyboard interaction to Slider component

Hi,

I have used a slider using AS3 and I made it mouseEnabled. I want to operate this slider only with Mouse but when it gets focused, slider is also sensative to keyboard events (arrow keys). I have used following eventListener.

BezierSlider.addEventListener(SliderEvent.THUMB_DRAG, thumbDragHandler);

Is there a way from where I can disable keyboard input for this slider.

Any help in solving this trouble is greatly appreciated.

Thanks,
Suyog
