To get someone's attention in a channel conversation or a chat, @mention them. Just type @ before their name and then select them from the menu that appears.
When an @mention recipient receives a notification, selecting it takes them directly to the point in the conversation where they were mentioned.
To get the attention of an entire group, type
- @<team name> to notify everyone on that team
- @<channel name> to notify everyone in that channel
If you're in a chat rather than a channel, you can notify everyone in the chat by typing @everyone in your message.
Important
A team owner must first enable these features.
