Understand your actions in Slack

In Slack, work happens in channels and direct messages (DMs). You can send messages and files, mention other people to get their attention, pin important messages to find them again later or star items to keep them in a special place just for you. Here’s a breakdown of how these features behave so you don’t have to guess.
