In looking at NSControl.h there is a NSKeyboardUI category definition with the following instance method declaration

- -- (void)performClick:sender;

This category is defined a number of places and at least some of them indicate that the type for sender should be (id)sender.
How is it NSControl does nothing to indicate the type?
Is id a default or is it somehow inherited in this situation?
