# Click and move the mouse pointer without a mouse

If you have difficulties using a mouse or other pointing device, you can control the mouse pointer using the numeric keypad on your keyboard. This feature is called mouse keys.

1. Fare clic sull'icona a destra nella barra dei menù e selezionare Impostazioni di sistema.

2. Fare clic su Accesso universale.

3. Selezionare la scheda Puntamento.

4. Switch Mouse Keys on.

5. Make sure that `Num Lock` is turned off. You will now be able to move the mouse pointer using the keypad.

These instructions provide the shortest way to enable mouse keys using only the keyboard. Select Universal Access Settings to see more accessibility options.

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 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; 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 Simulare il clic col pulsante destro 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.
