since a few days I have attached my new KBTalking Pure 60% to my single board computer and I am very pleased with this combination....

But one thing drives my curiosity:
For what is a numLock key good for on a numpad-less (tenkeyless) board?
Any ideas?
Google does not help much here...
Thank you very much in advance for any help!
Best regards and have a nice weekend!
Best regards,
