When a channel name is bold in the channel list (like #general in the image above), there is new activity in that channel. Click on the channel name to switch to that channel.


Unread messages

Slack can handle unread messages in three different ways. When you select a channel with unread messages, Slack can:

  • Start you where you left off (at the oldest unread message) and mark the channel as read
  • Start you at the newest message and mark the channel as read
  • Start you at the newest message but leave the older messages unread

To choose between these options:

  1. Click your workspace name in the top left to open the menu.
  2. Select Preferences.
  3. Click the Mark as Read tab.
  4. Under When I view a channel, select the option you'd like best.

Note: If you choose to start at the newest message and there is more unread channel activity than fits on your screen, you'll see a blue bar at the top of your messages view:

To return to the oldest unseen message, click the   up arrow on the left to catch up on the conversation.

If you're already up to speed, click the close icon on the right (or press Escape) to mark the channel as read.


Set an unread point

If you need to come back to a channel later, you can set an unread point.

  1. Hover over the oldest message you’d like to mark as unread.
  2. Click the   Show message actions icon.
  3. Click Mark unread.

Tip: You can also set an unread point by holding Alt and selecting a message.

Your main view in the app is the channel you're currently in. To read another channel, swipe left to right to open the channel list and simply tap the channel you'd like to read.

If a channel name is bold then there's new activity in that channel. Unread channels will appear at the top of the channel list.

If you go to a channel, and there is more unread activity than fits on your screen, by default Slack will display a blue bar at the top of the messages view:


To go to the oldest unseen message in the channel, simply tap the blue bar.

To mark the channel as read, instead tap the  close icon at the right-hand end of the bar.

Note: To disable the blue unread bar, swipe from right to left, tap Settings, Advanced, and toggle Mark as Read Immediately.

To set an unread point in a channel, long-press a message, then tap Mark Unread. All messages sent after and including this one will count as unread.
