What does “Controller Key” mean in Interface Builder > Inspector > Bindings?

Question

I can\'t find in the Docs where they explain all those fields and what they mean. Especially \"Controller Key\" is not clear to me.

Answer 1

Take a look at this topic: Cocoa Key Value Bindings: What are the explanations of the various options for Controller Key?

I posted an explanation of where to find definitions for all Controller Key's there.
