Re: Converting keyCode&modifierFlags to NSString

I'm letting the user press a key combination (to define a shortcut), 
and I want to display the key combination to the user. Therefore it 
would be the best if that could be done by passing the keycode or so 
and the modifierflags to some function that returns the human 
comprehensable character.

Best,
Fabian
