Q. How are the control buttons at the top of the screen used?

A. The control buttons at the top of the screen enable the user to access the many operational modes of the Verti-Chord Keyboard app. The user simply double-taps an unselected (White) control button to select it (button color changes to Blue), or double-taps an already selected (Blue) control button to deselect it (button color changes to White), which respectively engages or disengages the operational mode associated with that control button. The remaining FAQ pages explain the functionality of the various operational modes of the Verti-Chord Keyboard app.
