Please help regarding PMDG B738 key bindings

In PMDG B738, i want to key binding:

  1. VNAV (i can’t find the key binding in msfs’ , control options)
  2. autobrake (all autobrake in msfs’ control options not working)
  3. STD altimeter

If you all know, please tell me.
I don’t want to use 3rd party key binding apps.

Because your looking at PMDG, have you gone to their site for help? SDK most likely the answer, maybe. FSUIPC7 will do it, but you don’t wan’t 3rd party.

Many key bindings on PMDG will not work for me. I have Battery/avionics/landing gear bound on my throttle unit. Only the landing gear works. I just do everything with mouse, and that if you read introduction, mostly that is what it says too. MSFS has narrow working relationship with PMDG planes. It something I have futzed with for weeks. MSFS calls all those things something different, and I cannot figure out what that is, or how to set them.
