Flash Navigation - TV Remote control

Question

What would be the best way to set up a navigation system that acts like a TV remote control using Flash and AS3? I'm building an interactive demo that will simulate playing content and voting on your TV, using navigation similiar to say "Direct TV's remote control". Navigating each page through your remote with assigned keyboard commands.

The remote arrow keys will move your selection up, down, right, left, etc...

How would you approach this, before I get to deep I want to know if there's a better approach. Am I on track or would you do it differently? I was thinking of making each page an array and its nested movieclips in there own array -- will be used to navigate through them. But as I start to add more pages, the code is getting really long and confusing. Here is some of what I have.... The ControllerLogic AS file contains the order of the pages as

 /* The ControllerLogic.as file contains an array of the order of the pages. Methods are stored for global access */
public static var myVoteSequence:Array = new Array("select", 
             "question", 
             "poll_result",
             "phone",
             "thanx",
             "rating");
