Add a send button to the message field
By default, you send messages in Slack by using the Enter key. If you'd like, you can add a send button in the message field to use instead.
Add the send button
- From your desktop, click your workspace name in the top left.
- Select Preferences.
- Choose Advanced.
- Under Input options, check the box next to Show send button. Press Enter to add a new line of text.
Tip: If you've added the send button, you can also type ⌘Enter on Mac or CtrlEnter on Windows to send a message.
