Threads, mentions and reactions in chat

Reply in a thread

• Hover a message and click the speech-bubble icon ("Reply in thread"), or open the ... menu and choose "Reply in thread".
• A Thread panel opens with the original message and its replies. The reply count is shown, for example "3 replies".
• Type in the box that says "Reply in thread…" and send.
• Use plain "Reply" (the arrow) to quote a message in the main conversation instead.
• Threads are not available in a conversation with an AI bot.

Mention people

• Type @ in the message box. A list of people in the conversation appears (up to six, filtered as you type).
• Pick a name to insert the tag. Only people still tagged in the final text are counted as mentioned.
• A mentioned person gets a notification and a mention count on that conversation in the sidebar.

React to a message

• Hover a message to see quick reactions, or open the ... menu for the full set and a "+" for more emoji.
• The quick set is thumbs up, heart, laugh, party, surprised and folded hands.
• Click a reaction chip under a message to add or remove your own. Hover it to see who reacted.

Edit and delete

• You can Edit your own messages from the ... menu. Press Enter to save or Esc to cancel. Edited messages show "edited".
• You can Delete your own messages. Channel owners, channel admins and firm admins can delete other people's messages in channels they manage.
• Deleting removes the message for everyone in the conversation.

Unread

• Conversations with new messages show a count in the sidebar; opening the conversation clears it.
• Mentions are counted separately so you can spot messages meant for you.
• Read markers are shown under messages so others can see who has seen them.

Formatting tips

The message box has buttons for Bold, Italic, Code and a bulleted list, plus an emoji picker. Messages are shown as plain text with simple formatting only, never as raw HTML.
