Key HIT/press event

I want to take key press event, ut this is not on specific field, its on page/window.

Example:
While doing automation, on web page I have short-cut key suppose M (keyboard key). So how should I achieve this? If it can be achieved by inserting a JavaScript then how can I write it? I'm beginner in JavaScript.

As you want it on the window I would add a eventListener function direct on the window object like this. You can google the keyCode if you want to change keyCode. This works with and without jQuery library :) http://jsfiddle.net

window.addEventListener('keypress', function(e) {
    e = e || window.event;
    switch(e.which) {
        case 77:
            if (e.ctrlKey) { 
               alert( "M + ctrlKey is down" );
               // do some here
            }
            else {
                alert("M is down")
            }
        break;
    }

}, false);

Try the following code:

<script>
  function keyEvent (e) {
    if (!e)
      e = window.event;
    if (e.which) {
      keycode = e.which;
    } else if (e.keyCode) {
      keycode = e.keyCode;
    }
    if(keycode == 77){
      alert('Hi!');
    }
  }
  document.onkeydown = keyEvent;
</script>

Using jquery you can do this as follow.

 $(document).keydown(function(e){
            if (e.keyCode == 77) { 
               alert( "M key pressed" );
            }
        });
