This is a follow-up question based on Why are keyboard keys staggered?. The accepted answer explained how this staggered design originates to earliest typewriter. My question is, why do they stagger in this way?
Take home row as the horizontal axis, then in the alphanum area you canʼt find two keys aligned horizontally. It might be explained by my observation that for old typewriters, each keyʼs lever must take a unique horizontal position.
I'm just wondering whether itʼs that later industrial designers never changed this, or that there are other reasons beyond path dependence?
