Actually I was finally able to detect something via kacpimon, but it was
elusive, and it's scaring me now! It wouldn't immediately show on live
stdout (the way the other touch-hotkeys, and normal keys, do), and I
even had trouble seeing it when trying to redirect stdout to a file!
Ctrl-C'ing would prematurely truncate the output, sometimes not
capturing it, even the more graceful Escape-exit wouldn't capture it
unless I waited or padded it with mouse movements. Ie. there is some
very weird delay going on, and maybe repetition, or something.
For example, I swear I only touched that info key 5 times here, and then
AFTERWARDS pressed the 'A' key twice, and then Esc. grep'ing for
'Type: 1' I was able to catch:

A more weird example, again I *swear* I first only touched that info key
*5* times, and then moved the mouse for a few seconds between 2 'A' key
presses, and finishing with Escape, but although it showed the two 'A'
key events properly, it also showed *11* "code 325" and 11 "code 330"
value1 events, out of order!?
