As the title states, nothing happens. I've remapped to different keys and still no joy. IF I place the path start then the keys will raise/lower but I can't pick a random elevation. Anyone else having this issue?
Oh, I think it just means that those keys lift the end of path (if you press once, as a ramp, if twice as stairs) but don't place the path until you make click. To elevate a whole portion and not only the end, it's shift.Interesting, I just tried Shift and it works in combo with the mouse. However, the official controls show U for up and J for down. I really thought someone from Frontier would respond to this but I guess not. See my screenshot.
