Star channel
This will mark a channel as important. This will move the channel to the top left of your sidebar so you have quicker access to it. To do this, click the star in the upper right corner while in the channel.
Mute channel
This will allow you to occasionally browse channel activity without being notified of unread messages. To do this, click into the channel you want to mute, click the cog in the upper center, and click on the drop-down menu “mute channel.”
Showing only unread/favorites
These options will allow you to show only your unread messages and favorite channels in the sidebar. To do this, go to Preferences-Advanced-Channel List and select “My unreads, along with everything I’ve starred.” You can also quickly access all of your unreads underneath your name and clicking “ALL UNREADS.”
Quick Switcher
This will allow you to quickly jump between conversations and channels. You can access this with simple keyboard shortcuts. On a Mac you can access it by hitting Command+K. ON a PC you can bring it up using Ctrl+K. On Linux, hitting Ctrl+K will also bring up this menu. To search for a channel quickly, type # before the team name to bring up channel options. In order to search for a user, you can type @ before the PennKey and it will start to populate users. You can also use Tab or Up/Down arrows to scroll through the lists.
Notifications
You can adjust your notification preferences globally for each team you are a member of, or more granularly on a per-channel basis. For example, you can choose to receive notifications only for direct messages, and you can set up “do not disturb” hours if you don’t want to receive notifications off-hours. By default, notifications for this team are disabled between 10PM and 8AM.
Visit Preferences-Notifications menu for global settings. To reach the per-channel settings, click on the settings (gear icon) at the top of the channel you want to adjust, then choose notification preferences. You can select different per-channel notification settings for the desktop client and the mobile client.
Threads
Threads can be a very useful tool for responding to questions in channels that can get noisy. If you're answering someone's question or continuing a conversation in a high-traffic channel, consider using threads. When hovering over a message, click on the talk bubble icon to respond in a thread.
