如何将键盘快捷键永久添加到Jupyter（ipython）笔记本？ [英] How to add keyboard shortcuts permanently to Jupyter (ipython) notebook?

问题描述

我有以下快捷方式配置，在Jupiter笔记本单元格中运行后有效：

I have the following configuration for shortcuts, that works after running it in the cell of Jupiter notebook:

%%javascript


IPython.keyboard_manager.command_shortcuts.add_shortcut('ctrl-q', {
    help: 'Clear all output',               // This text will show up on the help page (CTRL-M h or ESC h)
    handler: function (event) {             // Function that gets invoked
        if (IPython.notebook.mode == 'command') {
            IPython.notebook.clear_all_output();
            return false;
        }
        return true;                   
    }
  });

如何在启动时自动设置Jupiter笔记本进行初始化？

How can I setup Jupiter notebook to make this initialization automatically on startup?

我尝试将相同的代码（不含 %% javascript ）添加到 C：\ Users \< username> ; \ .ipython \profile_default\static \custom\custom.js 但它没有用。

I tried adding the same code (without %%javascript) to C:\Users\<username>\.ipython\profile_default\static\custom\custom.js but it didn't work.

我有只有一个配置文件，使用 ipython配置文件创建，Python 3.3，Windows 7创建。

I have only one profile, created with ipython profile create, Python 3.3, Windows 7.

提前致谢。

推荐答案

custom.js是此代码的正确位置。尝试将其包装如下（在块结束之前不要忘记 return true ）：

custom.js is the correct place for this code. Try wrapping it as follows (don't forget the return true before the end of the block):

$([IPython.events]).on("app_initialized.NotebookApp", function () {
    <your code>

    return true;
});
