Relevant Code Excerpt:

// listen to the click event
google.earth.addEventListener(placemark, 'click', function(event) {
  var text = 'Click:';

  function addToMessage(append1, append2) { 
   text += ' ' + append1 + ': ' + append2 + '\n' ;
  }

  addToMessage('target type', event.getTarget().getType());
  addToMessage('currentTarget type', 
               event.getCurrentTarget().getType());
  addToMessage('button', event.getButton());
  addToMessage('clientX', event.getClientX());
  addToMessage('clientY', event.getClientY());
  addToMessage('screenX', event.getScreenX());
  addToMessage('screenY', event.getScreenY());
  addToMessage('latitude', event.getLatitude());
  addToMessage('longitude', event.getLongitude());
  addToMessage('altitude', event.getAltitude());
  addToMessage('didHitGlobe', event.getDidHitGlobe());
  addToMessage('altKey', event.getAltKey());

  // Prevent default balloon from popping up for marker placemarks
  event.preventDefault(); 

  // wrap alerts in API callbacks and event handlers
  // in a setTimeout to prevent deadlock in some browsers
  setTimeout(function() {
    alert(text);
  }, 0);
});
