Question

I’m not sure how to pass the specific keystroke through the bind method..

$(document).bind('keyup', event, keyup_handler(event));

This is my lucky failing guess..

This is the method it gets passed too..

var keyup_handler = function(e){
  if (e.keyCode == 27) {
    close_lightbox();
    return false;       
  };
};

Another failing variation :

    var keyup_handler = function(e){
      if (e.keyCode == 27) {
        close_lightbox();
        return false;       
      };
    };

$(document).bind('keyup', keyup_handler(e));

Which returns:

 e is not defined

I think you might misunderstand the bind API.

With your code, you’re telling jQuery to bind undefined to keyup:

• You immediately invoke keyup_handler by writing keyup_handler(...). It returns undefined, which is what is passed to the jQuery bind call.
• The second argument (event) is also undefined.

Instead,

$(document).bind('keyup', keyup_handler);
