the current approach with the text does not always show which key links to which text line when the quickkeys is in a verticle position. yes it does show the little line and justifies the text in that direction, but that's not always enough for a quick glance.
A suggestion (depending on how functional your display is could be do do something like one of the things in the attached image.
Thanks for the suggestion. That does make it much easier to read and see what text goes with which button. I have passed this on to the driver team to review.
