Thanks for putting a lot of thought into this! I've used many KBs over the years, and haven't thought about the alignment of the number row at all. As an example, I just noticed that my Surface "Typepad" KB has a very narrow tilde / back-quote key (~ and `) which biases the "6" to the left. If this weren't the case than it would be more centered, but this is then thrown by the width of the "Backspace" key. Is numerical input (without the use of a number pad) covered at all in any of the QWERTY vs. Dvorak vs. etc. debates? They have mostly looked at character input to my knowledge, with little regard to numerical input. Thanks UHK for asking this question? (personally, I think I'd just adopt to whatever, but "power users" may have a different, justifiable position on this.) EDIT: As an aside, what width space-bar do most of you think you require? I've just been thinking about KB key-width, and the space-bar shaped elephant-in-the-room loomed it's lengthy head. Based on the visible wear patterns on my 7 year old laptop, I reckon I'd be more than happy if the space-bar only extended from "V" to "N". I assume the KB designers have already looked into this, and we've already reached "optimum space-bar", but I'd love to see some research. Anyone know of any studies that have been done that confirm why my space-bar needs to be more than five times larger than the standard letter key?
