Button - selected state (CS4)

[Race Bannon]

How do I create and control a line of text that i turned into a button. I want to have a selected state built into the button. is that possible? Previously I created a light next to the text that changes color or highlights when the button had been selected, but I would like the text to change color when it is selected and have script that I can use to reset the button state when another button is selected.
current button:

S1.addEventListener(MouseEvent.MOUSE_DOWN,click_S1);
function click_S1(evt:Event):void {
    Truck.gotoAndStop(16);
}

thank you in advance for your help

Don't use buttons for these purposes. Use MovieClips, and this will do the trick.
Buttons are way too simple for this.
