1. First of all, computer keyboards are divided into notebook keyboards and ordinary desktop keyboards. Ordinary desktop keyboards have more function keys than notebook keyboards, but not necessarily many functions. The notebook is just simplified. The notebook keyboard has a number area, and the small one has no number area on the right. The number area is shown below.

The numeric keypad is located on the right side of the keyboard and has 17 keys, including numeric keys, cursor keys and some control keys. among

2. The function key area is above the keyboard, including

The notebook also has an on/off key. F 1 to F 12 are functional areas. Press F 1, F2 and F3 directly, and there are other functions. For example, F 1 is generally to help, F2 is generally to change the file name, F3 is generally to find the next one, and F5 is to refresh the web page or desktop.

3. Typing keyboard area, also called main keyboard area or character keyboard area, has the format of standard English typewriter keyboard. There are 58 keys, including basic character keys and some system control keys. The number keys also have the function of symbols. There are symbols on them, but if you want to enter symbols, you need to press Shift first, and then press the number keys.

4, the number keys are followed by the letter go, which is the main source of input, mainly pinyin or five-stroke typing, and is a must-use area for everyone. There are also two symbols on the right side of the letter. The symbol marked below appears directly, and the symbol marked above needs to press Shift first.

5. The figure below shows the right half of a common keyboard, which is divided into control area and number area. In the upper part of the control area, Print Screen is the screen capture key, Home is the home key, Page Up and Page Down are the previous page, Delete is delete, and END is positioned at the end of the line. These are rarely used in the general population.

The four arrows below are arrow keys. In the Number field on the right, the num lock in the upper left corner is a number lock. When pressed, the number field will not print numbers, and some computers lock the numbers by default when they are turned on. The upper right area is addition, subtraction, multiplication and division, and the lower right area is enter, which is the confirmation key.

6. Other Ctrl is the control key, Alt is the combination key and replacement key, and Shift is the shift key, which means that you can mark after Shift.
