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. If for some reason your mouse or touchpad does not work, you can enable this feature and temporarily fix the mouse problem. This feature allows you to not only move the mouse, but also left click, right click, double click and drag and drop.
