Thanks, I found that. My joystick doesn't have a spare axis to assign
to the rudder, so I either use the keyboard or don't do slips!
Apparently, some joysticks have a twist axis for rudder assignment, but
it doesn't appear that my Cyborg has that. Just the normal X and Y axis
and the Z axis throttle lever.

I just auto-coordinate the turns. Otherwise I lost the intended
purpose for *me* where I wanted to concentrate on my scan, setting
up and flying an approach down to minimums. To fly an approach you
don't need to do slips until the last kick out during the flare. At
that point MSFS has done its job.
