Finally, you can control the volume without ever leaving the home row! No fussy touchbar controls, just a quick shortcut to bring the controls to the front (ctrl+cmd+v) and you can raise (J) or lower (K) the volume. Multiple output devices? No problem! Switch outputs and control the volume of each device individually.
