Fyi, something I figured out that makes using the volume buttons a little easier to use for aroma-
If you keep pressing volume down at least 4 or 5 times (depending on how many aroma options are shown on that screen), it will take you to the little menu option, pressing volume up one time moves to bottom left button (usually the next button), one more press of volume up will move to the back button, and another 2-4 presses will take up to whatever options that particular screen on aroma has.
Still nowhere as easy as just touching the screen but at least it's something
