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: Input Layer: Type: 1 Code: 28 Value: 0 Input Layer: Type: 1 Code: 325 Value: 1 Input Layer: Type: 1 Code: 330 Value: 1 Input Layer: Type: 1 Code: 330 Value: 0 Input Layer: Type: 1 Code: 325 Value: 0 Input Layer: Type: 1 Code: 325 Value: 1 Input Layer: Type: 1 Code: 330 Value: 1 Input Layer: Type: 1 Code: 330 Value: 0 Input Layer: Type: 1 Code: 325 Value: 0 Input Layer: Type: 1 Code: 325 Value: 1 Input Layer: Type: 1 Code: 330 Value: 1 Input Layer: Type: 1 Code: 330 Value: 0 Input Layer: Type: 1 Code: 325 Value: 0 Input Layer: Type: 1 Code: 30 Value: 1 Input Layer: Type: 1 Code: 30 Value: 0 Input Layer: Type: 1 Code: 325 Value: 1 Input Layer: Type: 1 Code: 330 Value: 1 Input Layer: Type: 1 Code: 330 Value: 0 Input Layer: Type: 1 Code: 325 Value: 0 Input Layer: Type: 1 Code: 325 Value: 1 Input Layer: Type: 1 Code: 330 Value: 1 Input Layer: Type: 1 Code: 330 Value: 0 Input Layer: Type: 1 Code: 325 Value: 0 Input Layer: Type: 1 Code: 325 Value: 1 Input Layer: Type: 1 Code: 330 Value: 1 Input Layer: Type: 1 Code: 330 Value: 0 Input Layer: Type: 1 Code: 325 Value: 0 Input Layer: Type: 1 Code: 330 Value: 1 Input Layer: Type: 1 Code: 325 Value: 1 Input Layer: Type: 1 Code: 330 Value: 0 Input Layer: Type: 1 Code: 325 Value: 0 Input Layer: Type: 1 Code: 30 Value: 1 Input Layer: Type: 1 Code: 30 Value: 0 Input Layer: Type: 1 Code: 1 Value: 1 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!?
