PMDG 777 VIDEO - Cockpit Scan & FMC

yeah it is one of the few little things added by PMDG that are for us in simalator and without real hardware. That indeed indicates when keyboard input is redirected to the FMC, oftenquicker than clicking button one by one.

That's the same thing though not sure it is shown in video, but with the blue thrust indicator on the Engine N1/EPR it shows what your controller position is so that when you disconnect AT you're hardware throttle match the commanded throttle. Not real but very convenient for us.
