• 方式一

  // KeyCodeCombination第一个参数是主按键，后面的参数为辅助按键（可变参数）
  KeyCombination keyCombination = new KeyCodeCombination(KeyCode.ENTER, KeyCombination.ALT_DOWN, KeyCombination.CONTROL_DOWN);  
  Mnemonic mnemonic = new Mnemonic(button, keyCombination);  
  scene.addMnemonic(mnemonic);
  

• 方式二

  // KeyCharacterCombination第一个参数是主按键，后面的参数为辅助按键（可变参数）
  KeyCharacterCombination a = new KeyCharacterCombination("a", KeyCombination.ALT_DOWN, KeyCombination.CONTROL_DOWN);  
  Mnemonic mnemonic1 = new Mnemonic(button, a);
  scene.addMnemonic(mnemonic1);
  

• 方式三

  KeyCodeCombination keyCodeCombination = new KeyCodeCombination(KeyCode.Y, KeyCombination.ALT_DOWN);
  scene.getAccelerators().put(keyCodeCombination, new Runnable() {  
      @Override  
      public void run() {  
          System.out.println("RUN");  
          System.out.println(Thread.currentThread().getName());  
      }
