Ok, I know there's no such thing as a stupid question, but here's one anyway...On a B737 NG, how do I change the IN/HPA setting on the outer part of the BARO switch on the EFIS? There's no key assignment listed for it, and any mouse clicks near the switch modify only the barometric pressure setting - the middle part of the switch.Geoff

Hi!You have to hold the Mouse over the Word "Baro" and click..Thats it.Ralf

So easy...I couldn't find it described anywhere, and I was using the mouse wheel to try to rotate it.Thanks Ralf.Geoff

And the assigned key combo is Shift+Tab+B which is labelled "EFIS press BARO" which I wrongly took to mean press the center "Baro" STD button.Geoff

Ah ok!I never try to find a Key setting for this.Thanks for this. Ralf
