I have just added the CodeHighlighterPlugin for my blog. So as to take it for the test run, I am posting it here. Below are some actionscript code to see everything works fine.

package  
{
	import flash.display.MovieClip;
	import flash.display.Sprite;
	import flash.events.MouseEvent;
	
	import flash.external.ExternalInterface;
	
	/**
	 * @version 0.1
	 * @author Saumya
	 */
	public class FlashMenu extends MovieClip
	{
		public var btnOne:Sprite;
		public var btnTwo:Sprite;
		public var btnThree:Sprite;
		
		public function FlashMenu() 
		{
			this.init();
		}
		
		private function init():void
		{
			trace(this, ' : init : ');
			this.btnOne.addEventListener(MouseEvent.CLICK, onUserClick);
			this.btnTwo.addEventListener(MouseEvent.CLICK, onUserClick);
			this.btnThree.addEventListener(MouseEvent.CLICK, onUserClick);
		}

Happy living
