In order to filter a Timeline, you first need to be on the Timeline screen. You can navigate there by either going to the main menu and selecting Insights and opening up the Timeline or by selecting Timeline on the Action Bar on the Points screen.

Timeline is a powerful tool for administrators to see what's happening throughout the building in real time and has options for sounds and desktop notifications to alert you when a Point is recorded.

Click Settings, then turn Desktop Alerts and Sounds to "On." If you minimize LiveSchool (while Timeline is open), every time a Point is recorded you'll hear a "ding," and see a desktop notification.
