# Click and move the mouse pointer using the keypad

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 鼠标键。

Open the Activities overview and start typing Universal Access.

You can access the Activities overview by pressing on it, by moving your mouse pointer against the top-left corner of the screen, by using CtrlAltTab followed by Enter, or by using the Super key.

Click Universal Access to open the panel.

Use the up and down arrow keys to select Mouse Keys in the Pointing & Clicking section, then press Enter to switch the Mouse Keys switch to on.

确保关闭了 Num Lock 数字灯，然后就可以用键盘来移动鼠标指针了。

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 (Fn) 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.

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

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

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

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。
