Is there a jQuery selector to get all elements that can get focus?
<p><a href="http://stackoverflow.com/questions/1599660/which-html-elements-can-receive-focus/1600194#1600194">This answer</a> tells which HTML elements can receive focus. Is there a jQuery selector that matches exactly these elements?</p>

<p>For now I'm just using <code>$('input,select,textarea,a')</code>, but I wonder if there's something more precise.</p>
