“Mentions” (using the @ symbol) are fun. But they’re also very useful to highlight someone in a group chat. As you are typing a message, type the At symbol (@), and a list of who’s in the group chat is displayed. Continue typing the name, and the menu will filter the group chat members to match for the person you’re looking for.

To select the group member you want to mention, you can:

  • Click the group member name.
  • Tab through the selections.
  • Use your up/down arrows.
