Get scancodes of Italian layout keyboard I'm lookin' for Italian keyboard scan codes.

I've searched the net but nothing that deals with Mac except for: 

/System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/HIToolbox.framework/Versions/A/Headers/Events.h 


But this does not contain Layout Related scan codes.

My questions:


Is there any official documentation about this?
Is there any software like 'dumpkeys' running on macOS?


If possible I'd prefer the triple (byte 1: Modifier, byte 2: Reserved, byte 3: Keycode 1) as defined in http://www.usb.org/developers/hidpage/
The nicest tool for examining keyboard events including the scan codes is Karabiner-EventViewer which is part of Karabiner-Elements.

It will show you the scan codes as they occur.
