The keyboard letters we use now are in the QWER order. Many people wonder why the keyboard is not sorted in order by ABCD. So, the orderly arrangement will not affect the typing speed?
In fact, it is the original intention of the inventor of the keyboard that you want to type slowly. The English keyboard first appeared on the typewriters at the end of the 19th century. It was initially arranged in alphabetical order, but as the typist’s hand speed became faster and faster, the typing bar didn’t have time to rebound, and the collision often caused damage. The technology at the time could not solve this problem. The problem, there is a clever engineer who thinks that since the speed of the rebound of the typing bar can’t be changed, it is not enough to make the typing speed slower.
Then the alphabetical order is disrupted, and the most frequently used O, A, etc. are handed over to the clumsy ring finger and little finger, while the lower frequency U, V, etc., is responsible for the most flexible index finger, so the keyboard is arranged. It has become what we are seeing now. Until now, although the technical problems have been solved, the habitual problems have not changed.
