Numlock button is located on the right side of the keyboard, above the numeric keypad and below the ribbon (indicator light); Located directly above the number key "7", it is the NumLock key, and the word "NumLock" is printed on the surface of the key position. This key function is enabled, and the small light above the key is always on. If this key function is turned off, the light will be turned off.

When the key processing is available, the number function of the numeric keypad will be available. You can press the corresponding key to input the corresponding number into the computer, and you can also add, subtract, multiply and divide through this keypad. If the function of this key is turned off, you can't enter any numbers, and you can't perform mathematical calculations from this ribbon.

On the commonly used 104 key (full keyboard) distribution map and notebook full keyboard distribution map, this key will be located above the numeric keypad, on the same line as division, multiplication and subtraction, and just below the function area, with "NumLock" printed on the key surface.

If it is not a full keyboard, the words "Num" or "numLock" will generally be printed on the upper right; If it is an 87-key keyboard, then there will be no such keys in this area.

Keyboard options:

1, the touch of the keyboard

As the input device with the most daily contact, touch is undoubtedly the most important. The handle is mainly determined by the strength of the key and the degree of resistance of the key. How to judge the feel of a keyboard will be tested from the following aspects: whether the elasticity of the key is moderate, whether the stress on the key is uniform, whether the key cap is loose or shaking, and whether the key position is appropriate.

Although different users have different requirements for the flexibility and key stroke of keys, a high-quality keyboard should be able to meet the usage habits of most users in these aspects, and it is necessary to ensure that the keys are evenly stressed and the key cap is firm, otherwise it may cause the keys to get stuck or make users feel tired.

2, the appearance of the keyboard

Appearance includes the color and shape of the keyboard. A beautiful and fashionable keyboard will add a lot of color to your desktop, while an old keyboard will make your work more boring. Therefore, for the keyboard, as long as you think it looks good, likes it and is practical.

3, keyboard work

The keyboard is low in cost, but it doesn't mean that it can be handled casually. The surface and edge of a good keyboard are exquisitely treated, and the letters and symbols on the keycap are generally laser carved, which feels concave and convex. Traditional keyboards have CapsLock (letter case lock), NumLock (numeric keyboard lock) and ScrollLock lights.

4. Keyboard layout

Although there is a standard for the allocation of keyboard keys, there is still room for manoeuvre for various manufacturers on this standard. An experienced manufacturer can use his experience to arrange the keys of the keyboard more considerate to users, while a small manufacturer can only follow the most basic standards, and even make a keyboard with poor key distribution because of poor quality.

5, keyboard noise

I believe that all users hate the noise generated by tapping the keyboard, especially those who are still working, playing games and surfing the Internet at night. Therefore, a good keyboard must ensure that it only produces less noise when hitting at high speed and does not affect others' rest.

6. Keyboard keys conflict.

In our daily life, we play some games more or less. When playing games, some key combinations will be used continuously, so this requires that these keyboards have these game keys without conflict.
