Some clarifications may be in order. As this is the Cocoa list, and there is no
other use of the term "binding" in Cocoa other than "Cocoa bindings", IMHO I
think it best to encourage every poster to only use the term "binding" (of any
conjugation) to refer to "Cocoa Bindings".
The "predefined keys" are not a function of bindings, they are simply
properties of the controller class(es). The list in IB just happens to be those
keys that the specific selected NSObjectController subclass implements. This is
a feature of IB, rather than any function of bindings per se. It will be
empty/disabled for any other class.
