<span>KeyStroke表示键盘或等效输入设备上的关键操作。</span>
<span>KeyStrokes只能对应于特定键的按下或释放，就像KEY_PRESSED和KEY_RELEASED键事件一样;</span>
<span>或者，它们可以对应于键入特定的Java字符，就像KEY_TYPED KeyEvents一样。</span>
<span>在所有情况下，KeyStrokes都可以指定修饰符（alt，shift，control，meta，altGraph或其组合），这些操作在精确匹配中必须存在。</span>
<p> <span>KeyStrokes用于定义高级（语义）动作事件。</span> <span>您不需要捕获每个按键，而是丢弃不感兴趣的按键，您关心的按键会自动启动他们注册的组件上的操作。</span> </p>
<p> <span>KeyStrokes是不可变的，而且是独一无二的。</span> <span>客户端代码无法创建KeyStroke;</span> <span>必须使用<code>getKeyStroke</code>的变体。</span> <span>这些工厂方法允许KeyStroke实现高效缓存和共享实例。</span> </p>
