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.

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

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 Mô phỏng phím chuột phải for information on how to right-click by holding down 5 or the left mouse button.

If you want to use the keypad to type numbers while mouse keys is enabled, turn Num Lock on. The mouse cannot be controlled with the keypad when Num Lock is turned on, though.

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.
