Barry,
For amplifier keying, the K3 has an adjustable T-R delay that is very
much longer than that provided by the K2. It may be easier to use that
than fooling around with the external TX inhibit function.
The TX inhibit is more useful to folks who operate VHF/UHF with a
sequencer to switch a chain of preamps and antenna mounted gear between
TX and RX - it can also used to steer the keyer input to one of 2
transceivers in SO2R setups.

Thanks Don. Although TX Inhibit is described in the latest C1 version
of the manual, I missed it because no mention is made of using it for
qsk amp control. It would have been nice to make +5V available on the
AUX I/O connector for the pullup wiring. Also, I'm not sure why the
manual text refers to the "ACC" labeled connector as "AUX I/O" -
shouldn't this be consistent?
I believe there's an omission in the manual - TX INH is not listed in
the CONFIG menu section and I believe it should be.
