title: Which keycode for escape key with jQuery
body: <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>
