  <title>开启粘滞键</title>

  <p><em>Sticky keys</em> allows you to type keyboard shortcuts one key at a
  time rather than having to hold down all of the keys at once. For example,
  the <keyseq><key xref="keyboard-key-super">Super</key><key>Tab</key></keyseq>
  shortcut switches between windows. Without sticky keys turned on, you would
  have to hold down both keys at the same time; with sticky keys turned on, you
  would press <key>Super</key> and then <key>Tab</key> to do the same.</p>

  <p>如果您感觉同时按住几个键有困难，可以考虑开启粘滞键。</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>Sticky Keys</gui> to <gui>ON</gui>.</p>
    </item>
  </steps>

  <note style="tip">
    <title>快速开启和关闭粘滞键</title>
    <p>Under <gui>Enable by Keyboard</gui>, select
    <gui>Turn on accessibility features from the keyboard</gui>
    to turn sticky keys on and off from the keyboard. When this option is
    selected, you can press <key>Shift</key> five times in a row to enable or
    disable sticky keys.</p>
    <p>You can also turn sticky keys on and off by clicking the
    <link xref="a11y-icon">accessibility icon</link> on the top bar and
    selecting <gui>Sticky 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>如果您一次按住了两个键，就可以临时关闭粘滞键，像平常那样输入快捷键。</p>

  <p>For example, if you have sticky keys turned on but press <key>Super</key>
  and <key>Tab</key> simultaneously, sticky keys would not wait for you to
  press another key if you had this option turned on. It <em>would</em> wait if
  you only pressed one key, however. This is useful if you are able to press
  some keyboard shortcuts simultaneously (for example, keys that are close
  together), but not others.</p>

  <p>选中<gui>若同时按两个键则禁用</gui>来启用它。</p>

  <p>You can have the computer make a “beep” sound when you start typing a
  keyboard shortcut with sticky keys turned on. This is useful if you want to
  know that sticky keys is expecting a keyboard shortcut to be typed, so the
  next key press will be interpreted as part of a shortcut. Select <gui>Beep
  when a modifier key is pressed</gui> to enable this.</p>
