I don’t know if all users are aware of this possibility, therefore I add this here:
if you want to add a new name for a waypoint or write a inReach message, you have two possibilities of entering them:
a) wheel (is is the default offered one)
b) keyboard (you get it if you tab on to above shown keyboard
Maybe that is helpful for someone (@Eric, thanks for the hint. I overlooked the keyboard availability, too).
