How to use your keyboard to control the mouse pointer in Windows 10?

This guide will show you how to use the keyboard to move and click with your mouse pointer rather than a mouse using the Mouse Keys feature. This can be useful if you have a motor impairment that makes using a mouse awkward, or if you struggle on your laptop with a touchpad or a mouse.

Note: You will need a keyboard with a numeric keypad in order to use Mouse Keys.

Short guide:

Open the Ease of Access settings by pressing the Windows key + U on the keyboard.

Scroll down and select Mouse in the left-hand column.

On the right of the screen, click or tap the toggle switch under Control your mouse with a keypad to turn it on.

Adjust the Pointer speed and Pointer acceleration sliders until you are comfortable with how the mouse pointer moves across the screen.
