This should do it..

$(document).keyup(function(e){
   if (e.which == 27){
     $('#closeButtonId').trigger('click');
   }
});

assuming that your cross button has a click handler attached that closes the overlay..

$('#closeButtonId').click(function(){
   $('#overlay').hide();
});

      if (e.keyCode ==27){
            $('#your x-button').click();
    }
