        $('body').keypress(function(e){
            alert(e.which);
            if(e.which == 27){
                // Close my modal window
            }
        });

Answer 1

check for keyCode && which & keyup || keydown

$(document).keydown(function(e){
   var code = e.keyCode ? e.keyCode : e.which;
   alert(code);
});

Answer 2

$(document).keyup(function(e) {

  if (e.keyCode == 27) { <DO YOUR WORK HERE> }   // esc
});

Answer 3

either use .keydown() or .keyup()...

Answer 4

The keydown event will work fine for Escape and has the benefit of allowing you to use keyCode in all browsers. Also, you need to attach the listener to document rather than the body:

document.onkeydown = function(evt) {
    evt = evt || window.event;
    if (evt.keyCode == 27) {
        alert("Escape");
    }
};
