# 有沒有一次將多行程式碼註解掉的快捷方式？

是的，你可以先選取多行，然後按下 `Ctrl-/` （斜線）(`command-/` （在 Mac 上）。如果你熟悉 [vi 或 vim 編輯器](http://www.viemu.com/a_vi_vim_graphical_cheat_sheet_tutorial.html)，你也可以 [啟用 vi 編輯器模式](https://www.overleaf.com//blog/19) 在 Overleaf 上，並使用標準的 vi 指令來註解。最後，如果你想在原始碼中加入區塊註解，也可以使用 `comment` 套件來將大段文字註解掉。只要加入

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

到你的導言區，然後使用

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

於文字中建立區塊註解。

# 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-tw/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.
