Fire in the Cockpit!

hehe, Just wanted to get your attention:I am trying to assign keys to Barometric controls under PMDG->General->Keyboard Assignments->ISFDNone seem to work. I have insured that no other mod or flight sim is using the keys used.For instance, I assign 'K' to '166 ISFD - Press Baro STD', then close. However, 'K' does nothing.The Documentation seems to only address the various doors and key assignments.Known bug?Any Ideas?Thanks,Mike Neese
