Recognize key combination during start of the app

Question

I have an option in my XCode app and i like to switch it like the i Apps: Hold ALT key during the starting of the app... My question is, how can i recognize the key or a key combination in:

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification { ... } 

or in the app delegate?

Any suggestion would be great.

The NSEvent won't be called without a first responder (if i'm right).

Of course i mean the option key. This does the job:

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
    if (CGEventSourceKeyState(kCGEventSourceStateCombinedSessionState,0x3A)) {
        NSLog(@"Option key...");
    }
}

If someone else need it.
