how to change the next waypoint, zoom in map view

[outbound]

Hello,

I'm just getting started with this sim. When I turn on autopilot and accelerate time I can quickly move from waypoint to waypoint in a misssion. But how do I change the next waypoint? For example can I change the next waypoint to the previously visited waypoint, such that the aircraft returns to where it was before. I think there is a way to do this, but I could not find any mention of it in the list of commands.

A separate question - how do you zoom in and out in the map view?

Thanks!

Those paths are uni-directional.

I use the scroll wheel on the mouse to zoom in on the map.
