And you know better than to press Caps Lock when entering passwords—Apple even alerts you when you have it accidentally enabled. Early key IBM keyboards had a numeric keypad that doubled as arrow and other keys for text-screen-based interactions. The Num Lock key was a product of the intermediate age, where mechanical and digital met.
IBM doubled up: It added a Num Lock key that flipped the numeric keypad to act as arrow keys to move a cursor around a screen-based interface, before computer mouses. On certain laptops, including older Macs, Num Lock had a different function.
What to do if your MacBook keyboard is not working
Lacking a numeric keypad, Num Lock turned part of the main keyboard into a pseudo-keypad. There was sometimes a unique Num Lock key, sometimes it doubled with a Clear key and Shift, and sometimes it was a function to invoke, like through F6 on a Mac.

It turned out the main drive is working fine without any problems. Check out this and this article from Apple. And guess what?

There is a key-combination for this: Command [ , and to go forward to the next insertion point Command ], 3. I can duplicate the issue if I touch the TrackPad, then hit either [ or ] the cursor will jump back to the last insertion point.
Things I Tried But Didn’t Work
The NisusWriter commands are very specific, the trackpad sequence is either bracket. I suspect that it might be happening anywhere there are similar key-combination shortcuts. I hope this helps. Hope this helps some people. The Apple woman was really snarky and not helpful. I expressed frustration, she was just looking for an excuse to hang up on me.
My God thank you. I was 5 seconds away from hurling my laptop out the window.
