How do I post in a channel
- Open “Chat” from the menu (or press the c key).
- Click the channel on the left, under “Channels” (for example “#general”).
- Type in the box at the bottom.
- Press Enter or the send button.

Shift+Enter starts a new line without sending. New messages appear on their own, without reloading the page.
A number next to a channel or a colleague shows how many unread messages you have there; a red mark means one of them is urgent. The total unread count also appears next to “Chat” in the menu and updates about once a minute.
