If you ever need to use the numeric keypad to act like a Mouse to move the cursor around on your Windows 10 desktop, here is how you can enable it.
Go to Settings app → Ease of Access → Mouse, and turn on the setting “Use numeric keypad to move mouse around the screen“.
The change takes effect immediately. Pressing the arrow keys on the numeric pad moves the cursor around the screen like using a Mouse. There is also an icon named MouseKey showing up in the system tray indicating that you have this feature turned on at the moment.
There are 2 more options related to MouseKeys that you also should enable to get the most out of this feature,
- Hold down Ctrl to speed up and Shift to slow down
- Use mouse keys when Num Lock is on
Comparing to the previous Windows, this version of MouseKeys works a lot better.
