you can do this with java script.

　　to hide toolbar, menu ... etc., open your web application with this JS function that you can set according to your needs :

　　 window.open("yourZKWebPage","windowName","width=200,height=100,toolbar=no,location=no,directories=no ,status=yes,menubar=no,scrollbars=no,resizable=yes");

　　And here, is an old code to intercept keyboard input, you can also customize it according to your needs :

　　function keydown() {

　　if ((window.event.ctrlKey) || (window.event.shiftKey) || (window.event.keyCode==18) || ((window.event.keyCode>=112) && (window.event.keyCode<=123))) {

　　if (window.confirm("Shortcuts are not allowed ! \nDo you want to exit this great site " ))

　　top.close();

　　else {

　　setTimeout("form.focus();",30);

　　window.event.returnValue = false;

　　}

　　}

　　}

　　document.onkeydown= keydown //All Keys are checked
