Slack 是一种流行的团队消息传递和协作应用程序,支持 Markdown 语法的子集。界面的不同部分提供不同级别的 Markdown 支持。
Slack 的消息界面是人们使用最多的界面。虽然明显缺乏对许多元素的支持,但提供了对一些基本语法的支持。
2019 年 11 月,Slack 推出了一个新的所见即所得的界面,如下所示。默认情况下,为所有用户启用此功能。最明显的变化是在界面控件中添加了格式按钮,但还有一个实时编辑器,可以在您键入后隐藏 Markdown 格式。您不必使用界面控件来格式化文本 — 您仍然可以使用下一节中描述的 Markdown 语法元素。

您可以在 Preferences > Advanced 中禁用所见即所得的界面。选择 Format messages with markup 设置,如下所示。启用此设置将隐藏所见即所得的格式按钮并禁用实时编辑器,以便您可以在键入时看到 Markdown 格式。
