Keyboard control on the app is similar to the [[Keyboard_AX|keyboard page]] on the system's touch screen. Entering Keyboard will stop anything that is currently playing and suspend the automatic schedule and disable quick functions while it is open. The status icon at the top right of the system's touch screen will show that it is in the keyboard mode.
Be sure to tap the back button to close Keyboard mode and allow the schedule to resume. Otherwise, the [[Keyboard_setup_AX|keyboard timeout]] will be in effect (one hour default after the last note played).
