 <p>这样得到的思维导图可以通过鼠标和快捷键进行操作，比如单击某个节点可以激活它，双击某个节点可以编辑节点文本，按下<code>Tab</code>键会给当前激活的节点添加一个子节点，按下<code>Enter</code>键会给当前激活的节点添加一个兄弟节点等等，完整的快捷键列表可以参考<a href="https://github.com/wanglin2/mind-map/blob/main/web/src/config/zh.js#L246">快捷键列表</a>。</p>
 <p>当然有些功能还是需要UI界面的，比如图标列表、编辑超链接等等，需要注意的是<code>simple-mind-map</code>库并不包含UI界面，所以需要你自己开发，然后通过<code>simple-mind-map</code>提供的相关API来操作，本教程的其他章节会向你介绍如何使用。</p>
