See the NSResponder documentation for a description how the key events are
interpreted. It is kind of complicated.

Anyway, in case you want to catch keys when some textfield is filled (is it
so?), I'd recommend to use the NSControl delegate method cotrolTextDidChange:
(see docs for it).

Ouch? Somewhat I don't understand: "- (NSString *)characters {}" is a
definition of method, which is named "characters" and returns a NSString
object. There should be its implementation between brackets.
