# 有没有一次注释掉多行代码的快捷方式？

可以，只需选中多行并按下 `Ctrl-/` （斜杠）（`command-/` （在 Mac 上）。如果你熟悉 [vi 或 vim 编辑器](http://www.viemu.com/a_vi_vim_graphical_cheat_sheet_tutorial.html)，你也可以 [启用 vi 编辑器模式](https://www.overleaf.com//blog/19) 在 Overleaf 中，并使用标准的 vi 注释命令。最后，如果你想在源代码中添加块注释，也可以使用 `comment` 包来注释掉大段文本。只需添加

```latex
\usepackage{comment}
```

到导言区，然后使用

```latex
\begin{comment}
...
\end{comment}
```

在正文中创建块注释。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/zh-cn/zhi-shi-ku/096-is-there-a-shortcut-for-commenting-out-several-lines-of-code-at-once.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
