Handling Key Events

any subclass of NSResponder can accept events

key events from NSWindow

subclass NSWindow, with MyWindow
in IB, set the window to use the custom class, MyWindow

override the following method in MyWindow:

- (void)keyDown:(NSEvent *)event
{
	switch ([event keyCode]) {
		case 121:{ // page down
			if([event modifierFlags] & NSCommandKeyMask) // only do something if the command key was also pressed
				// do something
			break;
		}
	}
}

key events from a custom view

make the view the first responder
- there may be a better way to do this, but you can use this:
```
[view becomeFirstResponder];

or

[window makeFirstResponder:view];
```
override the keyDown method in the view (see NSWindow above for example)
