Well, yes. However, I am not sure if having a "standard but
non-standard" key-code is of much use, since you neither can be sure
that the current device actually has a key-code that your app is
looking for, nor that all the keys your device has actually map to
one of the X keycodes.
I would think that the key-code should be whatever the device
actually delivers (device-specific), because only then do you have a
safe 1:1 mapping, whereas the same event also carries the unicode
character (sequence) that is equivalent.
