I can make so sense of the manual.

I wish to fly direct to a different way point but I cannot work out how. I did this last night, but tonight, no idea  :-/

Looks like I've got a 5 hour flight of manually setting the heading. I want to fly to another waypoint as the flight plan took me away from the airport then back over it, which would have me turn around. As I took off from the opposite heading, I just continued ahead with a view that I could fly direct to.
