title: What does return super.onOptionsItemSelected(item) do?
body: <ol>
  <li><p>It's given in the android docs of onOptionItemSelected that <code>When you successfully handle a menu item, return true. If you don't handle the menu item, you should call the superclass implementation of onOptionsItemSelected() (the default implementation returns false).</code>.But I don't get what the last one means. what does it mean by saying <code>call the superclass implementation of onOptionItemSelected</code>. What does calling the superclass do</p></li>
  <li><p>Also please do explain what <code>return.super.onOptionsItemSelected(item)</code> do?</p></li>
  </ol>
