<title>Click and move the mouse pointer using the keypad</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>Accessibility</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,
by using <keyseq><key>Ctrl</key><key>Alt</key><key>Tab</key></keyseq>
followed by <key>Enter</key>, or by using the
<key xref="keyboard-key-super">Super</key> key.</p>
</item>
<item>
<p>Click <gui>Accessibility</gui> to open the panel.</p>
</item>
<item>
<!-- TODO investigate keyboard navigation, because the arrow keys show no
visual feedback, and do not seem to work. -->
<p>Use the up and down arrow keys to select <gui>Mouse Keys</gui> in the
<gui>Pointing & Clicking</gui> section, then press <key>Enter</key>
to switch the <gui>Mouse Keys</gui> switch to on.</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>
