L-1011 autopilot controller mappings

[Acktu]

I am currently in latest and greatest L-1011 version 1.0.1.
I can't seem to find out very basic controller mappings for most autopilot functions.  The only one I was able to find out is AP disconnect and AT/TM disangage.

However, I tried, "Autopilot ON" and I see the switch move to CMD, however it does not take control of the plane.   Also, how can I toggle spoilers? "Toggle arm spoilers" which is what I use for other aircraft, does nothing.  I also can't find ALT or HDG hold.  Again, very basic AP functions I would like to map to my controller but this plane for some reason doesn't have any controller mappings unless I am blind.

Has anyone figured out AP mappings, or is this bugged?
