jquery - How to handle ESC keydown on javascript popup window

Question

I have a javascript window.open popup, and I want the popup to close itself when the user presses the ESC key. I can't figure out how to hook the keydown event (and on what object?) so that I can catch the ESC key.

I'm using jQuery.

Try something like this:

$(document).keydown(function(e) {
    // ESCAPE key pressed
    if (e.keyCode == 27) {
        window.close();
    }
});
