+</span> * @class Ext.Action
+ * <p>An Action is a piece of reusable functionality that can be abstracted out of any particular component so that it
+ * can be usefully shared among multiple components. Actions let you share handlers, configuration options and UI
+ * updates across any components that support the Action interface (primarily {@link Ext.toolbar.Toolbar}, {@link Ext.button.Button}
+ * and {@link Ext.menu.Menu} components).</p>
+ * <p>Use a single Action instance as the config object for any number of UI Components which share the same configuration. The
+ * Action not only supplies the configuration, but allows all Components based upon it to have a common set of methods
+ * called at once through a single call to the Action.</p>
+ * <p>Any Component that is to be configured with an Action must also support
+ * the following methods:<ul>
+ * <li><code>setText(string)</code></li>
+ * <li><code>setIconCls(string)</code></li>
+ * <li><code>setDisabled(boolean)</code></li>
+ * <li><code>setVisible(boolean)</code></li>
