function fireEvent(type, element) {
    var evt;

    if(document.createEvent) {
        evt = document.createEvent("HTMLEvents");
        evt.initEvent(type, true, true);
    } else {
        evt = document.createEventObject();
        evt.eventType = type;
    }

    evt.eventName = type;
    evt.keyCode = 13;
    evt.which = 13;

    if(document.createEvent) {
        element.dispatchEvent(evt);
    } else {
        element.fireEvent("on" + evt.eventType, evt);
    }
}

fireEvent('keydown', document.
