Even the Same Computer Uses a Different Layout by Country
Using a computer abroad, you'll often be thrown off by a layout that differs from the QWERTY you're used to. France uses AZERTY, Germany uses QWERTZ β each country's keyboard layout evolved a little differently to suit the characteristics of its own language.
Frequently Asked Questions
Why does QWERTY remain standard if it isn't the most efficient layout?
Because the vast majority of people worldwide are already so accustomed to QWERTY, the learning cost of switching to another layout is generally considered to outweigh any efficiency gains.
Does learning Dvorak really make you type faster?
In theory it's advantageous because it reduces finger travel distance, but the real-world benefit varies a lot from person to person, and it takes a considerable amount of time to learn.
