The keyboard is divided into four areas: function key area, main keyboard area, status indication area, and control key area.
The keyboard is further divided into four types of indications: numbers, symbols, letters, and functions.
Fingering distribution of the keyboard:
The so-called standard fingering is to put the left index finger on the letter F (there is a small protrusion on the F key, which we usually call blind coordinates), the right index finger on the letter J (the J key also has blind coordinates), and then align the four fingers side by side, each on the adjacent key.
The second part of standard fingering is the parallel movement of the fingers, which means that from the moment you put your hand on the keyboard, the four fingers of each hand are aligned side by side, up and down. The third part of standard fingering is the principle of diagonal movement, which is to move up and down in a left-high and right-low manner, whether you have your left hand or your right hand. That is, the movement norm for the left index finger is a 4 r f v line, and the movement norm for the right index finger is a 7 u j m line.
The 5 t g b next to the left index finger was hit by the left index finger. Similarly, the four keys of 6 y h n next to the index finger of the right hand are hit by the index finger of the right hand. Once you have an initial impression of standard fingering, you can understand the fingering division of other keys on the keyboard.

There are a total of 26 English letters, 10 numbers and 11 commonly used symbols, plus a long space bar, these key functions are very simple and clear, and they are used to enter words and numbers when typing in documents and software chats. Of course, if you enter English, you can press the keys directly, and if you enter Chinese, you need to use pinyin or Wubi input method.

One on the left and one on the left and one on the keyboard, which is convenient for the left hand and right hand to press separately, but the function is the same. Normally, pressing the English letter key is lowercase, hold down the "upper gear key" at the same time, and then press the letter key, and the input is uppercase.
In addition, there are two symbols on each number and symbol button, and you can enter the symbol printed on the top by pressing and holding down the "upper key" while pressing a key. For example, if you press and hold the "upper button" and press the number 8 button, you will enter "*".
