If ever your touchpad dies on your laptop or your mouse stops working on your desktop, it’s worth knowing how to move the mouse cursor and navigate around until you can get your system back to normal.

Thankfully, there is a feature built into Windows called Mouse Keys that allow you to use the numeric keypad on your keyboard to move your mouse around the screen. It even allow you to simulate a right-click, double-click and left-click. On desktops, you will use the keypad at the far right of the keyboard. On laptops, you will probably have to enable Num Lock or press and hold the function key before pressing the numbers.

The shortcut to enable Mouse Keys is by pressing ALT + Left SHIFT + NUM LOCK at the same time. Note that you have to use the left SHIFT key as the right one will not work. You can also enable or disable Mouse Keys in Windows by opening the Control Panel and click on Ease of Access. Under Ease of Access Center, open Change how your mouse works and then check Turn on Mouse Keys.
