title: How close popup window on ESC keydown on javascript
body: <p>My problem is like this: <a href="https://stackoverflow.com/questions/1481626/how-to-handle-esc-keydown-on-javascript-popup-window">ESC-problem</a></p>
  
  <p>But the difference is that, I do not have access to content of child window( I cant put script in that).</p>
  
  <p>Is that possible that I handle <code>esc</code> keydown in parent window for child window.</p>
