found easter egg (incl releasing trigger) in as code, but no clue how to fire it

Question

I've been recently looking through decompiled AS3 code from Ubisoft's "The Settlers Online" and found an easter egg along with something that looked like trigger, but - as I have never read AS3 before, and even if - decompiled code is often too obscure to understand, even for experienced coders , not to say for me. so, here I came up with question: anyone has a clue how to trigger that easter contained in this tiny AS3 snippet:

package Utils
{
   import flash.events.KeyboardEvent;
   import flash.ui.Keyboard;
   import mx.core.UIComponent;

   public class RabbidCode
   {


      private var sequence:Array;

      public function RabbidCode()
      {
         while(true)
         {
            while(true)
            {
               switch(0)
               {
                  case 0:
                     super();
                     this.reset();
                     (global.getApplication() as UIComponent).stage.addEventListener(KeyboardEvent.KEY_UP,this.handleKeyUp);
                     return;
                  case 1:
                     continue;
               }
            }
         }
      }

      private function handleKeyUp(param1:KeyboardEvent) : void
      {
         while(false)
         {
         }
         var _loc2_:int = this.sequence.shift();
         if(param1.keyCode == _loc2_)
         {
            if(this.sequence.length == 0)
            {
               this.action();
            }
            else
            {
               return;
            }
         }
         this.reset();
      }

      private function action() : void
      {
         while(true)
         {
            while(true)
            {
               switch(0)
               {
                  case 0:
                     var _loc1_:* = ["Graubart","Pandur","Amaris","Helene","Ravel","EnglishFellow","Shark","AJ","David","Ferhat","Kalle","Buan","Franck","Alexandra","Bine","Nils","ZockenMitKatze","Aenlin","Miriam","Crystaliq","Buddy","Céline","Ally","Jason","Omris","Orowa","Lyedra","Anna","Talamira","Taku","Throril","Naknaknak","Infran","Linki","Henning","Dzan","Sandra","Pherlin","Andreas","Alexander","Angel","Bogdan","Carlos","Chris","Claudiu","Denis","Ignacio","Linda","Marcel","Matthias","Michael","Mirco","Oliver","Paul","Catalin","Bob","Rudi","Ruslan","Simon","Sonja","Stefan","Tobias","Jakub","Violeta","Maggie","Clara","Erkan","Sabrina","Sebastian","Patrick","Aeyline","Penelopa","Ondgrund","Belegha","Acadma","Omris","Amta","Maxhylere","Kumakun","Orowa","Saqui","Nanuq","Taku","Aylea","Anash","Zoltan","Grubur","Veythyru"];
                     global.ui.mCurrentPlayerZone.mSettlerKIManager.setNameList(_loc1_);
                     return;
                  case 1:
                     continue;
               }
            }
         }
      }

      private function reset() : void
      {
         while(false)
         {
         }
         this.sequence = [Keyboard.UP,Keyboard.UP,Keyboard.DOWN,Keyboard.DOWN,Keyboard.LEFT,Keyboard.RIGHT,Keyboard.LEFT,Keyboard.RIGHT,"B".charCodeAt(0),"A".charCodeAt(0)];
      }
   }
}

Answer 1

This combination (up, up, down, down, left, right, left, right, A, B) is a well known Konami code so just pressing those keys should trigger it.

The real question here is when, or if at all this code is loaded so that it actually is hooked-up and can be triggered.
