Got a curious request today from a customer, they were looking for a "left-handed tenkey keypad", with the minus, plus and enter for the tenkey on the left so the user can use their left pinky to hit the enter key. I was a little surprised to see that even "left-handed" keyboards exist, with the tenkey on the left but having looked for the left handed tenkey, I'm coming up dry. Any ideas about this and/or where to fine one?
