event.shiftKey is a boolean. true if the Shift key is being pressed, false if not. altKey and ctrlKey work the same way.
So basically you just need to detect the keydown as normal with onkeydown, and check those properties as needed.

I think this one is more informative than the selected answer, as it actually describes the behavior of the proper functionality, whereas the OA just presents a bunch of browser hacks for making sure this functionality works.

people should use event.key or event.code, beware of deprecation
Jeton Thaçi
what exactly is deprecated @AkinHwan can you give us reference!?
var onkeydown = (function (ev) { var key; var isShift; if (window.event) { key = window.event.keyCode; isShift = !!window.event.shiftKey; // typecast to boolean } else { key = ev.which; isShift = !!ev.shiftKey; } if ( isShift ) { switch (key) { case 16: // ignore shift key break; default: alert(key); // do stuff here? break; } } });

All of this code is not needed (anymore). Please see the other answer.
