They come out either as insertText: or as doCommandBySelector: (see NSResponder.h for these three methods). insertText: will be used for text input, doCommandBySelector: with an appropriate selector for special keys like arrow keys. The relevant selectors are mostly listed in NSResponder.h. The default NSResponder implementation of doCommandBySelector: checks whether the receiver responds to the given selector, and if so calls it; otherwise it is passed on to the next responder's doCommandBySelector:.
That’s actually for NSTextInput, which according to the docs is slated for deprecation in favor of NSTextInputClient. If you need to be compatible with Mac OS X 10.4 and earlier, than NSTextInput is the way to go, but otherwise, NSTextInputClient is probably a better choice.
