        return %^The second responsibility of a component is to handle user interface behavior.  This usually means having a method for each link or submit button it displays.  The Counter class has two such methods: <tt>#increment</tt>, which maps to the ++ link, and <tt>#decrement</tt>, which maps to the -- link.  Their implementations are very simple:
      <pre>
      <b>increment</b>
        count := count + 1

      <b>decrement</b>
        count := count - 1
      </pre>
      #{counter}
      Methods that are directly mapped to links or buttons are sometimes known as <i>action</i> methods
      <p>
      You can use this editor to modify the <tt>#increment</tt> action method.  For example, you can try changing it to
      <pre>
      <b>increment</b>
        count := count + 2
      </pre>
      Test your changes with the counter above
      #{incrementEditor}
      ^
