  <title>开启慢速键</title>

  <p>如果您希望按键后屏幕延迟显示对应字母，可开启<em>慢速键</em>。这意味着您必须按住您想要输入的每个键一小会儿，对应字母才会显示。在输入过程中会意外一次按下多个键时，或发现在键盘上第一次就能按下正确的键有困难时，可以使用慢速键。</p>

    selecting <gui>Slow Keys</gui>. The accessibility icon is visible when
    one or more settings have been enabled from the <gui>Universal Access</gui>

  </note>

  <p>拖动<gui>可接受延迟</gui>滑块，设定按住多长时间才能输入一个按键。</p>

  <p>You can have your computer make a sound when you press a key, when a key
  press is accepted, or when a key press is rejected because you didn’t hold
  the key down long enough.</p>
