@mention someone

An @mention is like a tap on the shoulder—a way to get someone's attention in a channel conversation or a chat.

1. In the box where you type your message, type @, then type the first few letters of the person’s name. You can also @mention entire teams and channels.

2. Select the person. Repeat for as many people as you want to @mention.

Each person you @mention gets a notification in their Activity feed. Check for a red circle next to Activity right now to see if someone has @mentioned you!

Start a call from a chat

2. Type the name or names into the To field at the top of your new chat.

3. Select Video call   or Audio call  to start a call.
