[Elecraft] K3: SUB button used as a Macro switch?

[Oliver Johns]

Dear Wayne,

A while back, you asked for ideas people might have for firmware.  Here is one.

I have no sub-receiver, and am not likely to install one.  I see that SUB button sitting at the bottom of the front panel unused.  Maybe there could be an option CONFIG: SubButton with two choices, NOR and MACRO.  Then the SUB button could be used for a nice user-defined macro.
