  <title>使用键盘来点击和移动鼠标指针</title>

  <p>如果您使用鼠标或其他指针设备有困难，可以用数字小键盘来控制鼠标指针。这个特性称作 <em>鼠标键</em>。</p>

  <steps>
    <item>
      <p>Open the <gui xref="shell-introduction#activities">Activities</gui> overview and
      start typing <gui>Universal Access</gui>.</p>
      <p>You can access the <gui>Activities</gui> overview by pressing on it,
      by moving your mouse pointer against the top-left corner of the screen,
      using <keyseq><key>Ctrl</key><key>Alt</key><key>Tab</key></keyseq>
      followed by <key>Enter</key> or using
      <key xref="keyboard-key-super">Super</key>.</p>
    </item>
    <item>
      <p>Click on <gui>Universal Access</gui> to open the panel.</p>
    </item>
    <item>
      <p>Use the up and down arrow keys to select <gui>Mouse Keys</gui> in the
      <gui>Pointing &amp; Clicking</gui> section then press <key>Enter</key> to
      switch <gui>Mouse Keys</gui> to <gui>On</gui>.</p>
    </item>
    <item>
      <p>确保关闭了 <key>Num Lock</key> 数字灯，然后就可以用键盘来移动鼠标指针了。</p>
    </item>
  </steps>

  <p>The keypad is a set of numerical buttons on your keyboard, usually
  arranged into a square grid. If you have a keyboard without a keypad (such as
  a laptop keyboard), you may need to hold down the function (<key>Fn</key>)
  key and use certain other keys on your keyboard as a keypad. If you use this
  feature often on a laptop, you can purchase external USB or Bluetooth numeric
  keypads.</p>

  <p>小键盘上的每个数字代表一个方向。例如，按<key>8</key>是向上，按<key>2</key>是向下。按<key>5</key>是向单击，快速按两下是双击。</p>

  <p>Most keyboards have a special key which allows you to right-click,
  sometimes called the <key xref="keyboard-key-menu">Menu</key> key. Note,
  however, that this key responds to where your keyboard focus is, not where
  your mouse pointer is. See <link xref="a11y-right-click"/> for information on
  how to right-click by holding down <key>5</key> or the left mouse button.</p>

  <p>如果这时您想输入数字，只要开启 <key>Num Lock</key> 数字灯，<key>Num Lock</key> 灯亮的时候鼠标不能被键盘控制。</p>

  <note>
    <p>键盘上面还有一排普通数字键，它们不能控制鼠标指针，只能当数字按键使用。</p>
