ok thanks John.
The 777 goes from THR REF + VNAV SPD straight to SPD + VNAV PTH
Yes SMOC if you were in THR + FLCH SPD it will go to SPD + ALT ( basically the same )
After capture of the selected FL the Elevators are controlling the Altitude and the A/T the Speed.
Now the Bus is different, I believe they have a mode for "capture" and another for hoding it? ALT "star" is the capture I think??? Similar to LOC "star" on approach.
