Windows 10 includes a feature that allows you to use the numeric keys as a mouse. Not much is noticed due to low usage. This feature seems to be primarily intended for desktop computers, but it can also be used on laptops.

This feature allows you to not only move the mouse, but also left click, right click, double click and drag and drop.
