  <title>开启回弹键</title>

  <p>开启<em>回弹键</em>可以忽略快速重复的按键动作。例如，如果您患有手颤，这会导致在您只想按一次时却多次重复按键，这时应开启回弹键。</p>

  <steps>
    <item>
      <p>Open the <gui xref="shell-introduction#activities">Activities</gui> overview and
      start typing <gui>Universal Access</gui>.</p>
    </item>
    <item>
      <p>Click on <gui>Universal Access</gui> to open the panel.</p>
    </item>
    <item>
      <p>Press <gui>Typing Assist (AccessX)</gui> in the <gui>Typing</gui>
      section.</p>
    </item>
    <item>
      <p>Switch <gui>Bounce Keys</gui> to <gui>ON</gui>.</p>
    </item>
  </steps>

  <note style="tip">
    <title>快速开启和关闭回弹键功能</title>
    <p>You can turn bounce keys on and off by clicking the
    <link xref="a11y-icon">accessibility icon</link> on the top bar and
    selecting <gui>Bounce Keys</gui>. The accessibility icon is visible when
    one or more settings have been enabled from the <gui>Universal Access</gui>
    panel.</p>
  </note>

  <p>使用<gui>可接受延迟</gui>滑块来更改第一次按键后回弹键等待多长时间后才被认为是第二次按键。如果您希望计算机因按键过快而忽略按键动作时均发出声音，可选择<gui>当某个键被拒绝时发出蜂鸣声</gui>。</p>
