Apologies if it was posted before, I couldn't find it. It amazes me the fact that nobody on TV and other mass-media channels did not mention anything about the Heading Selector knob from the MCP. All the TV "specialists" are talking about some " pre-programmed" waypoints. I speculate it would be a lot faster and perhaps more convenient to disengage the LNAV and change the direction using the Heading Selector instead of reprogramming the flight path on the CDU.
