title: Keep focus after insertHtml with CKEditor
body: <p>I made a simple plugin to insert HTML into an inline CKEditor. But after every insert, the editor loses focus. Is there a way to keep focus and keep the cursor active after inserting the HTML?</p>
  
  <pre><code>editor
      .addCommand("InsertHtml",
      {
          exec: function ()
          {
              editor.insertHtml("&lt;span&gt;xxx&lt;/span&gt;");
          }
      });
  </code></pre>
