Should the plugin do something special when it gets
                focus?</p></li></ul></div><p>Recall that the plugin core class must extend <a class="ulink" href="../api/org/gjt/sp/jedit/EditPlugin.html" target="_top">
        <code class="classname">EditPlugin</code></a>. In QuickNotepad's plugin core
        class, there are no special initialization or shutdown chores to
        perform, so we will not need a <code class="function">start()</code> or
        <code class="function">stop()</code> method.</p><p>The resulting plugin core class is lightweight and straightforward
        to implement:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><div class="informalexample"><pre class="programlisting">public class QuickNotepadPlugin extends EditPlugin {
  public static final String NAME = "quicknotepad";
  public static final String OPTION_PREFIX = "options.quicknotepad.";
}
</pre></div><p>The class has been simplified since 4.1, and all we
                defined here were a couple of <code class="classname">String</code> data
                members to enforce consistent syntax for the name of properties
                we will use throughout the plugin.</p></li><li class="listitem"><p>These names are used in <code class="filename">actions.xml</code>
                for each of the menu choices. This file is discussed in more
                detail in <a class="xref" href="plugin-implement-actions.html" title="The Actions.xml Catalog">the section called “The Actions.xml Catalog”</a>. Each
