Honeycomb Bravo - FSX - Assign keystroke to a Bravo button?

[fppilot 4,371]

I am working in FSX SE and have the Bravo tap-dancing for me.  But for a couple of my Milviz GA models, namely the B55 Baron and C310R, I wish to assign the keyboard "H" key to a button on the Bravo's row of 7 buttons.  That to turn Carb Heat on/off.  The only two Conditions or Variables I find available in the Bravo's FSX Confgurator app are "Carb Heat Available" and "Apply Heat to Systems" .  Neither of those work.  I cannot determine a method to assign a keystroke in the configurator, and FSUIPC is not recognizing Bravo buttons on that row.

Hi Frank, glad your getting things sorted.  Not really related to throttles hardware but i dont think the C310 needs carb heat.  Not sure about the B55 but the C310 is fuel injected....
