[AS2] Using Arrow Keys for selection [HELP PLS!]

I’m in need of some help.

I am trying to create a four button system that is controlled using either your mouse or arrow keys.

I need to create a Key Listener to allow the highlighting and selecting of each button . The arrow keys allow you to select button when you reach the last button it returns to the first button, and the enter key allows you to select the button.

I just can’t figure this out…any help would be appreciated!
