        evt = (evt) ? evt: ((window.event) ? window.event: "");
        keyCode = evt.keyCode ? evt.keyCode: (evt.which ? evt.which: evt.charCode);
        if(keyCode == 13){
            $('embed').remove();           
            $('body').append('<embed autostart="true" loop="false" src="__PUBLIC__/Voice/OK.wav" hidden="true" VOLUME="100"></embed>');
