objective c - Cocoa - NSEvent Respond to the SHIFT key?

I was wondering if NSEvent responds to the "Shift" key on the keyboard. I am logging the keyCodes when debugging my app and I don't get a keyCode value for the shift key.

Thanks,

Kevin

EDIT: This is the code I am using from a user response.

-(void)keyDown:(NSEvent*)event
{   

    if ([event modifierFlags] == NSShiftKeyMask) {
        NSLog(@"Shift key pressed");
    }
}

The Shift key is still not being recognized...

Take a look at the flagsChanged: method of NSResponder.

Something like this:

- (void) flagsChanged:(NSEvent *) event {
    if ([event modifierFlags] & NSShiftKeyMask) {
        //Do something
    }
}
