There are several keyboard layouts.

The keys on the keyboard are not arranged according to ABCD, but according to QWER. There is no logic, which is actually caused by different keyboard layouts. The so-called keyboard layout is the way the keys of the keyboard are distributed on the keyboard. When keyboards were invented, they were really arranged according to ABCD. Later, people found that the typing speed was too fast and it was easy to get stuck, so they changed it to the inefficient QWER. Later, there were two keyboard layouts, Dvorak keyboard and malt keyboard, but QWER keyboard was used more. Let's see how many keyboard layouts there are. 1. What does keyboard layout mean?

Keyboard layout refers to the schematic diagram or definition of the key distribution on the keyboard. The layout of the keyboard used by people is determined by the software in the computer, and the characters on the keys represent the standard layout of the keyboard.

Keyboard layout mainly affects the order of keys, and does not involve other aspects. The layout people usually use depends on the country or language they use.

Second, there are several keyboard layouts.

There are many kinds of keyboard layouts. Here is a brief introduction for you:

1, ABCD keyboard

At the beginning of the invention of keyboard, the layout of keyboard came in alphabetical order, which is ABCD keyboard. Later, people found that this layout was too fast to type, which would affect the normal operation of the keyboard. In order to solve this problem, other keyboard layouts were invented.

2. Standard keyboard

This was invented to prevent typing from being too fast. This keyboard layout puts the most commonly used letters in the opposite direction, which slows down the typing speed to the maximum extent and avoids the key jam. Although QWERTY keyboard layout is common, it is inefficient. For example, most typists are right-handed, but with the QWERTY keyboard, the left hand takes up 57% of the work. The two little fingers and the ring finger of the left hand are the weakest fingers, but they are used frequently. The utilization rate of letters in the middle column only accounts for about 30% of the whole typing workload, so in order to type a word, you often have to move your fingers up and down.

3. Dvorak keyboard

Because of the appearance of blind typing technology, the keystroke speed is enough to meet the needs of daily work. But in 1934, a man named dvorak invented a new arrangement, Dvorak keyboard, in order to make his left and right hands alternately type more words. This keyboard can shorten the training period by 1/2 times and increase the average speed by 35%. Dvorak's keyboard layout principle is to hit the left and right hands alternately as far as possible to avoid one-handed combo; The average moving distance of verbal attack keys is the smallest; The most commonly used letters should be arranged in the position of the guide key.

4. malt keyboard

This keyboard is more reasonable and efficient than Dvorak keyboard. It changes the staggered arrangement of the original keys, makes the thumb easier to use, and makes it easier to reach keys that were originally far away from the center of the keyboard, such as Backspace. But the malt keyboard needs special hardware to be installed on the computer, so it has not been widely used.

Although there are many keyboard layouts, QWERTY is the most widely used one, which is neither reasonable nor efficient. I have to say that it is a classic case of bad money driving out good money.
