如何在ipython qtconsole中打开括号的自动完成功能

在我的Jupyter笔记本电脑中，我喜欢的括号会自动完成。

如果我进入终端并运行，jupyter qtconsole则控制台将打开。它是这个版本：

Jupyter QtConsole 4.2.1 Python 2.7.11 | Anaconda 2.1.0（32位）| （默认值，2015年12月6日，18:08:45）键入“版权”，“信用”或“许可证”以获取更多信息。

IPython 4.2.0-增强的交互式Python

在qtconsole中，括号不会自动完成-引号也不会。我可以打开它们吗？

我有以下文件：
/home/myname/.jupyter/custom/custom.js
/home/jason/.ipython/profile_default/static/custom/custom.js

在custom.js下面的内容中-我可以添加到这些文件中以获得自动完成行为吗？

 *
 *
 * Placeholder for custom user javascript
 * mainly to be overridden in profile/static/custom/custom.js
 * This will always be an empty file in IPython
 *
 * User could add any javascript in the `profile/static/custom/custom.js` file
 * (and should create it if it does not exist).
 * It will be executed by the ipython notebook at load time.
 *
 * Same thing with `profile/static/custom/custom.css` to inject custom css into the notebook.
 *
 * Example :
 *
 * Create a custom button in toolbar that execute `%qtconsole` in kernel
 * and hence open a qtconsole attached to the same kernel as the current notebook
 *
 *    $([IPython.events]).on('app_initialized.NotebookApp', function(){
 *        IPython.toolbar.add_buttons_group([
 *            {
 *                 'label'   : 'run qtconsole',
 *                 'icon'    : 'icon-terminal', // select your icon from http://fortawesome.github.io/Font-Awesome/icons
 *                 'callback': function () {
 *                     IPython.notebook.kernel.execute('%qtconsole')
 *                 }
 *            }
 *            // add more button here if needed.
 *            ]);
 *    });
 *
 * Example :autoCloseBrackets: true,
 *
 *  Use `jQuery.getScript(url [, success(script, textStatus, jqXHR)] );`
 *  to load custom script into the notebook.
 *
 *    // to load the metadata ui extension example.
 *    $.getScript('/static/notebook/js/celltoolbarpresets/example.js');
 *    // or
 *    // to load the metadata ui extension to control slideshow mode / reveal js for nbconvert
 *    $.getScript('/static/notebook/js/celltoolbarpresets/slideshow.js');
 *
 *
 * @module IPython
 * @namespace IPython
 * @class customjs
 * @static
