Yep, just do something like this:
- (void)keyDown:(NSEvent *)theEvent {
[self interpretKeyEvents:[NSArray arrayWithObject:theEvent]];
[NSCursor setHiddenUntilMouseMoves:YES]; // to make the cursor hide while you are typing like Mac users are used to
}
Then, you override insertText:replacementRange: to get text that should be typed. If you want to do something like the arrow keys, then override the various methods in NSResponder. For example, if the user hits the right arrow key, your object will get a -moveRight: message. If you do this, then your app will still work with custom key bindings the user has set up (since the text system is completely configurable). So say a user decides he wants his keypad to work like a PC with “Num Lock” off, and sets up his key bindings so that the 4, 8, 6, and 2 keys on the keypad map to the same methods that the arrow keys are bound to. In this case, your app will Just Work™ without even having to know about this user’s unusual setup.
