How do I quit or force quit applications on a Chromebook? The best way to quit out of an application on a Chromebook is to quit through the menu within the application. If this does not work, you can two finger tap on the icon for the application within the tray. The third way is to stop the task through the task manager. If the application is ended through the two finger tap on the icon in the tray or through the task manager, any USB connected devices must be disconnected and reconnected to the Chromebook to again make them available. For any BT connected devices, you will need to reset these to make the available for the Chromebook again.
