title: How can I handle shortcuts when LSUIElement is set to YES?
body: <p>When <code>LSUIElement</code> is set to <code>NO</code> most of shortcuts are handled by application's main menu. But when <code>LSUIElement</code> is set to <code>YES</code>, there is no main menu and then no common shortcuts are forwarded to a first responder.</p>
  
  <p>The naive solution would be overriding <code>performKeyEquivalent:</code> for each view/window class. But I only want to handle common shortcuts, not special one. So, I'm looking for a better solution.</p>
