Exactly how you described. Move as it moves now, straight ahead with a normal click. If you hold ctrl the cursor might highlight, or change icon, then if you click it’ll find the direct path to a road, follow the road in the direction to the point closest to where you want to go (if it’s on the road even easier), then off that point directly to the direction you clicked. Unless the point you clicked is really close then it just moves to it regardless if you’re holding ctrl which I don’t know why you would. Makes long distance travel via road so much easier.
