1.Main Keyboard Area:

The main keyboard, also known as the standard typing keyboard, contains 26 English letters, 10 number symbols, various punctuation marks, mathematical symbols, special symbols and other 47 character keys, as well as a number of basic function control keys.

1) Letter key: All letter keys are engraved with uppercase English letters on the key surface, indicating that the upper block symbol is uppercase and the lower file symbol is lowercase (that is, under normal circumstances, the lower file symbol is entered when pressing this key). The arrangement of the keys is the same as that of a standard English typewriter.

2) Numeric keys: Part of the 1st row of the main keyboard, with numbers engraved on the key surface. Enter the number on the lower key face on a single time.

3) Shift key: The marking symbol on the key surface is "shift" or "" There is a shift key on the left and right sides of the fourth row of the main keyboard, which has the same function, which is used for case conversion and input bending of the upper gear symbol.

4) CapsLock: In the middle of the left side of the 104 main keyboard, it is used to convert the upper and lower case input states, and this keyboard is a repeated key. Usually (in the boot state) the system defaults to input lowercase, after pressing this key, the "capslock" indicator light in the middle of the upper right of the keyboard lights up, indicating that the default state is uppercase at this time, and the letters with the input rolling configuration are uppercase letters.

Click this key again and the "Capslock" light is off, indicating that the status is lowercase at this time, and the entered letters are lowercase letters.

5) Space bar: also known as the [space] key, the longest key on the entire keyboard. Pressing this key once will enter a whitespace character and move the cursor one square to the right.
