Каким образом отличить нажатие клавиши «влево» от Num 4 с отключенным Num Lock?

• Key code: 75, raw code: 65430 без NUM LOCK
  
• Key code: 75, raw code: 65460 с нажатым NUM LOCK
  

import org.jnativehook.GlobalScreen;
import org.jnativehook.NativeHookException;
import org.jnativehook.keyboard.NativeKeyEvent;
import org.jnativehook.keyboard.NativeKeyListener;

public class KeyEventDemo implements NativeKeyListener {

    public static void main(String[] args) {
        try {
            GlobalScreen.registerNativeHook();
        }
        catch (NativeHookException ex) {
            System.err.println(ex.getMessage());
            System.exit(1);
        }

        GlobalScreen.addNativeKeyListener(new KeyEventDemo());
    }

    @Override
    public void nativeKeyPressed(final NativeKeyEvent nativeKeyEvent) {
        System.out.println("Key code: " + nativeKeyEvent.getKeyCode()
                + ", raw code: " + nativeKeyEvent.getRawCode());
    }

    @Override
    public void nativeKeyReleased(final NativeKeyEvent nativeKeyEvent) {}

    @Override
    public void nativeKeyTyped(final NativeKeyEvent nativeKeyEvent) {}
}

@param rawCode the hardware code associated with the native key in this event.
