Follow-up Comment #2, bug #25395 (project gnustep):

at one point in time i remember the exact opposite was true, the internet
agrees.

http://objc.toodarkpark.net/AppKit/Classes/NSEvent.html#//apple_ref/occ/instm/NSEvent/keyCode

Returns the code for the keyboard key associated with the receiving key
event. Its value is hardware-dependent. Raises an
NSInternalInconsistencyException if sent to a non-key event.

http://developer.apple.com/documentation/Cocoa/Reference/ApplicationKit/Classes/NSEvent_Class/Reference/Reference.html#//apple_ref/occ/instm/NSEvent/keyCode

The virtual key code. The returned value is hardware-independent.


from the book "cocoa programming" by anguish, buck, and yactman
"this is a device-dependent code. while it is provided for key-down, key-up,
and flags changed events, it is generally a very bad idea to use it." 

the first version of Hillegass's "cocoa programming for Mac OS X" also
mentions it as hardware dependent and afaict has no example usage.

it doesn't appear that there exists any apple provided definition
here is a thread on the subject.
