But where are the instance variables target and action?

Directly accessing variables is usually a no-no in Cocoa; not because it's impossible, but because it makes for poor encapsulation (for example, it may be changed by anyone at any time, and you for example would not be able to retain the new value or release the old one).

Virtually all access is done via properties, which are pairs of - someValue/-setSomeValue: methods. Interface Builder should set the action *property*, which means calling -setAction: on the button. (See also the Cocoa docs on Key-Value Coding for more.)
