I am a CAD professional, and everyday I use a number pad that I can set off to the left side of my keyboard, and next to my 3DConnection SpaceMouse. The numberpad is generic and works ok, but I have found none on the market that has a backlight. I wish your company offered a MX number pad with backlight. Yes, I have a number pad on my MX Keys S, but even though I am right handed for CAD work having an independent number pad on the left side is invaluable. Thank You.
