Question

I need help to create keyboard shortcuts in my Java program. As can be seen in my code below, I need to have a keyboard shortcut that is Ctrl+T which works properly and prints "test", but the shortcut Ctrl+Shift+T does not print "test2" as expected, nothing happens:

KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(
    new KeyEventDispatcher() {
        public boolean dispatchKeyEvent(KeyEvent e) {
            switch (e.getID()) {
                case KeyEvent.KEY_PRESSED:
                    if (e.getKeyCode() == java.awt.event.KeyEvent.VK_T && 
                        e.getModifiers() == java.awt.event.InputEvent.CTRL_MASK) {
                        System.out.print("test");   
                    } else if (e.getKeyCode() == java.awt.event.KeyEvent.VK_R && 
                               e.getModifiers() == java.awt.event.InputEvent.CTRL_MASK &&
                               e.getModifiers() == java.awt.event.InputEvent.SHIFT_MASK) {
                        System.out.print("test2");  
                    }       
                break;
            }
            return true;
        }
    }
);

The modifiers of an InputEvent are a bit field, so you test them using bitwise operations, not simply ==. But a simpler approach is to use the is*Down() methods of InputEvent:

if (e.getKeyCode() == java.awt.event.KeyEvent.VK_R && 
    e.isControlDown() && e.isShiftDown()) {
