Is it possible to detect ctrl key state on dblclick event

I am using Google maps API version 3. I would like my double click event handler to work as follows: google.maps.event.addListener(map, 'dblclick', function(e) { if (/* ctrl is pressed */) { doSomething(e) } else { doSomethingElse(e) } }); It looks the the event handler only provides a MouseEvent which does not contain information about the keyboard state. I need the LatLng information so I doubt that I can use JQuery's event handling. Am I out of luck here?
I suppose you could keep a global variable that says if ctrl is pressed down and update it using jQuery event handling
