Please add it.  This will avoid many angry phone calls to support and huge
flames on the Internet.

Other buttons don't need it.  Reset to factory defaults (and EEINIT) really
do need it.

Many hams are old with shaky hands and many also suffer from Parkinsons
(N6RA, KG6I, NI6T, N6BV, W2LE, ...).  It's far too easy to tap something
dangerous like this when it was not intended.  And what if your cat starts
swatting at the USB mouse and clicks Factory Reset?  :-)  OK, the latter is
unlikely, but the former is a serious concern.

By TUNE POWER I assume you mean the *TUNE LP* menu setting.  The *TUNE
LP* setting
now defaults to only 5W (used to be 10W).  So, using all the Elecraft
defaults, tapping the ATU TUNE button on the KPA1500 won't always work,
because the amp.'s tuner will only get 5W drive instead of 20W.
