The keyboard is divided into four areas: function key area, main keyboard area, status indication area and control key area.
The keyboard is divided into four instructions: numbers, symbols, letters and functions.
Finger distribution of keyboard:
The so-called standard fingering means that the left index finger is placed on the letter F (there is a small protrusion on the F key, which we usually call blind typing coordinates), the right index finger is placed on the letter J (the J key also has blind typing coordinates), and then the four fingers are placed side by side on the adjacent keys.
The second part of the standard fingering is the rule of finger parallel movement, that is, from the moment you put your hand on the keyboard, the four fingers of each hand should be side by side and aligned up and down. The third part of the standard fingering is the principle of oblique movement, that is, whether your left hand or your right hand, you should move up and down in a way of high left and low right. In other words, the movement standard of the left index finger is 4 R F V line, and the movement standard of the right index finger is 7 U J M line. Among them, the 5 T G B next to the left index finger is played by the left index finger. Similarly, the four keys of 6 Y H N next to the right index finger are also played by the right index finger. When you have a preliminary impression of the standard fingering, you can understand the fingering division of other keys on the keyboard.
