Hi,
I don't think this is widely known, so I thought I post it.
You can map commands conveniently to two keys, may come in handy for multi-engine planes.
So I mapped magneto one to "M"+"1" key, Fuel cock one two "F"+"1" etc.
So for, say the fuel cocks in the Blenheim, I press F and 1 simultaneous and the corresponding lever one moves.
Perhaps some might find it useful.
Michael.
