I'm looking for a way to go back to a particular point in space, kind
of like a bookmark, in MS FSX.

I know there has to be a way to do this. Fly to a certain point, hit
CTRL+ALT+Z, or whatever and have it remember where you were. Then you
could hit CTRL+ALT+X, or whatever and go back to this exact point and
start your approach, hold, etc. again.

Thanks for any help.
