But the piece that jumped out at me was this:
What’s curious—the least popular keys are Capslock and Right Mouse Button. Somewhere around 0.1% of all keypresses together. It’s time to make some changes to keyboards.
I've been whining about this for years. Why is it that the least-used key on my keyboard not just in a prominent position, but also bigger than most other keys? I can I invest in a real alternate keyboard with a different layout (my husband's a big fan of the Kinesis keyboards, initially to cope with carpal tunnel). But surely it's time to re-visit the standard key layout?
