I would put the second paragraph here first, for emphasis.  If you're 
dealing with anything that handles real text input--NSTextField, for 
example--then you definitely do not want to be overriding -keyDown:. 
The real solution to the OP's question is to start with some 
tutorials; any introductory set of Cocoa examples would answer these 
sorts of very basic questions, for which the answer is usually going 
to be "hook it up in IB".
