Which keycode for escape key with jQuery
<p>I have two functions.  When enter is pressed the functions runs correctly but when escape is pressed it doesn't. What's the correct number for the escape key?  </p>

<pre><code>$(document).keypress(function(e) { 
    if (e.which == 13) { $('.save').click(); }    // enter (works as expected)
    if (e.which == 27) { $('.cancel').click(); }  // esc   (does not work)
});
</code></pre>
