Windows has a built in tool called "MouseKeys" that allows you to control the pointer with the numeric keypad on your keyboard.
To enable MouseKeys, you can go to Control Panel > Accessibility Options > Mouse tab and check Use MouseKeys. Another way to enable MouseKeys is by simultaneously pressing the “left ALT + left SHIFT + NUM LOCK” keys. Take note that it only works if you press the left side ALT and SHIFT. If you use the right side, it wouldn’t work. When MouseKeys is enabled, you can temporary disable it by pressing the Num Lock key.
Here are the keys used by Mousekeys to navigate your cursor :
2 = Move Down
8 = Move Up
4 = Move Left
6 = Move Right
7 = Move Diagonally Top Left
9 = Move Diagonally Top Right
1 = Move Diagonally Bottom Left
3 = Move Diagonally Bottom Right
5 = Simulate Mouse Single Left Click
(+) = Simulate Mouse Double Click
(-) = Simulate Mouse Right Click
(*) = Simulate Both Mouse Buttons Click At Once
By default, the cursor will move really slow. You’ll have to go to Settings and adjust both the top speed and acceleration to the highest. To set the maximum speed at which the mouse pointer moves when you hold down a MouseKeys direction key, under Pointer speed, drag the Top speed slider. To set how quickly the mouse pointer accelerates to its maximum speed when you hold down a MouseKeys direction key, under Pointer speed, drag the Acceleration slider.
