Patricia shared a great tip with me about using the numeric keypad as a trackball or mouse replacement. She writes:

 “I used it for years as my only pointing device, as I cannot drive a rodent, and that’s all there was. Now, of course, we have trackballs, touchpads, touchscreens, and all kinds of choices, but I still favor using the numbers in some circumstances, or in emergencies. My laptop has a touchscreen driver that periodically seizes up and freezes.”

Here’s how to enable in it in Windows 10:

Type Ease of Access Mouse Settings into the search box and click on the result.

Under Mouse Keys, turn on Use numeric keypad to move mouse around screen.

Patricia suggests recommends sliding the Use mouse keys when Num Lock is on option to the Off position.

You can also set up these features by opening the Control Panel and going to the Ease of Access Center.

Select Change how your mouse works.

Scroll down to Turn on mouse keys and tick the box next to it.

Click on Set up Mouse Keys to adjust the Pointer Speed. Patricia suggests choosing the highest speed and the fastest acceleration, setting the NUM LOCK to the Off position, and making sure that you tick the box to display the mouse keys icon on your taskbar.

Here’s what that icon looks like on your taskbar:

Patricia leaves the utility running all the time:

“Not only in case something else fails, but it’s terrific for image management and photo editing because it’s really precise. I’m clumsy with a trackball, and possibly most people aren’t able to manage superfine movements with their usual pointing devices. It will move very small distances and always in perfectly straight lines. Need to crop an almost invisible distance larger or smaller? Just click “0” at the sizing handle, click a direction key, and then click “.” to drop. Want to resize an area while maintaining the aspect ratios? Line up your cursor over a corner sizing handle, click “0” to lock, move the corner in a perfectly straight line with a diagonal number key, click “.” to drop.”

Here’s a list of numeric keypad commands:
