@pvagner Thanks for all the pointers!
The idea is that you can indeed select a nearby bus stop by pressing space or the keys 1,2 or three. When one of the closest features is selected, a popup with information opens up. It _should_ read this aloud, but I'm still figuring out how to let ORCA do this...
Additionally, one can also answer some questions about the selected location to help others.
The shaking is a good idea as well! It'll take me a few more days to implement this though.
