Set your message formatting preference

If you prefer to format your messages with markup instead of Slack's built-in formatting when using Slack on your desktop, you can adjust your preference. With markup, you'll see formatting applied to your messages after you send them, and the formatting toolbar won't display in the message field.

  1. From your desktop, click your workspace name in the top left.
  2. Select Preferences from the menu.
  3. Select Advanced.
  4. Under Input Options, check or uncheck the box next to Format messages with markup.

Note: There are some formatting limitations when markup is selected.
