[Elecraft] K3 Button Box

 > Are there any commercial solutions out there?

It looks like the Genovation CP24 would be one commercial solution.
It is programmable ~100 bytes per macro and if one of the keys is
dedicated as a toggle the user can program up to 46 macros (24 normal,
24 alternate or shifted).  Note: the software provides for more than
one shift/toggle key but the keypad has only one LED indicator which
would make it difficult to handle more than two levels of macros with
a toggle - of course more than two levels are available without any
ambiguity using "shift" keys.

The CP24 is available in multiple versions - a serial version that
could probably be connected directly to the K3 for stand alone use
(without computer logging software) and a USB version that could be
used (with port splitting software) in a computer with a logging
program.
