 <note style="tip">
 <p>These instructions provide the shortest way to enable mouse keys using
 only the keyboard. Select <gui>Universal Access Settings</gui> to see more
 accessibility options.</p>
 </note>

<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 keypads.
</p>

<p>
Each number on the keypad corresponds to a direction. For example, pressing
<key>8</key> will move the pointer upwards and pressing <key>2</key> will move
it downwards. Press the <key>5</key> key to click once with the mouse, or
quickly press it twice to double-click.
</p>

<p>
Most keyboards have a special key which
allows you to right-click; it is often near to the space bar. 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>
If you want to use the keypad to type numbers while mouse keys is enabled, turn
<key>Num Lock</key> on. The mouse cannot be controlled with the keypad when
<key>Num Lock</key> is turned on, though.
</p>

<note>
    <p>
    The normal number keys, in a line at the top of the keyboard, will not
    control the mouse pointer. Only the keypad number keys can be used.
