Hi,

I am using overlib.js lib to display the popups when clicked on a link. I am tyring to close the popup using ESC key.

The blow code works but when I tab over the link and hit enter key to open the popup I have to press ESC key twice.

Can I make it close by pressing ESC key only once?

function addEvent(obj, evType, fn, useCapture){
  if (obj.addEventListener){
    obj.addEventListener(evType, fn, useCapture);
    return true;
  } else if (obj.attachEvent){
    var r = obj.attachEvent("on"+evType, fn);
    return r;
  } else {
    alert("Handler could not be attached");
  }
}

var Try = {
  these: function() {
    var returnValue;
	
    for (var i = 0; i < arguments.length; i++) {
      var lambda = arguments[i];
      try {
        returnValue = lambda();
        break;
      } catch (e) {}
    }
	
    return returnValue;
  }
}

function closeInfo(event){
 var e = event || window.event
 var characterCode = e.which || e.keyCode;
 if(characterCode == 27){
   return Try.these(
        function() {return nd();},
		function() {return nd();}
