Let's take a look at the computer keyboard knowledge summary-The hope that the novice friend to learn more about the keyboard help.

The keyboard is one of the input devices for the computer, and we have a lot of trouble adapting to those weird alphabet keys when we have computer classes at school. Although the use of the mouse now is relatively high, but a large number of basic operations or rely on the keyboard to complete. Many users in the choice of keyboard, often just tap the key, they put the choice of focus on the mouse. In fact, the keyboard selection is no less than the mouse, especially often for word processing users.

Tips for relaxing

Most of today's keyboard sales only advertise how stylish it is and how many shortcuts it has. Admittedly, the appearance of a beautiful keyboard is very eye-catching, but the real good keyboard, but the best feel for the selling point. Touch refers to the feeling of the finger when the user uses the keyboard and the feeling of the wrist when using it. If the key cap is difficult to press, or if the wrist is suspended for a long time, it will make you feel uncomfortable.

In fact, what we want is just a keyboard that doesn't look too fancy and ergonomically structured. I believe many users have heard of the term "ergonomics" and have seen the keyboard with an arc of key arrangement, with an angle in the middle of the alphabet keyboard. When we use the keyboard, the forearm naturally separates a certain angle, the ordinary keyboard structure, needs the hand to hit the keyboard to keep parallel, so easy to cause muscle strain. and ergonomic keyboard, so that the operator's palms and forearm axis naturally into a straight line, not easy to cause muscle strain. Although this design is helpful to users who use the keyboard for a long time, this change is not acceptable because their operating habits have been fixed by the key arrangement of the regular keyboard.

The keyboard now being sold in the market has begun to improve the comfort of user operations, which are mainly growth (shortening) the key, increasing the number of shortcuts (usually not customizable), changing the height of the keyboard to meet the user's operating habits, and adding a tray for the wrist.

Small knowledge: The key process is the button from the normal state to the finger to press the resulting displacement length, the standard desktop keyboard keys for 3.8mm~4.0mm.

The above mentioned several methods to improve the operation of comfort, add shortcuts and add pallets are users to open product packaging can be seen, keyboard height with the tray can be to a certain extent to ease the user's fatigue, and the key process needs users in the trial when their own experience. When the user hits the key, when you encounter a keyboard that is very short (a slim keyboard similar to a notebook keyboard, its key is only 2.5mm~3mm), the first feeling is that you do not need the finger too hard, a little press to complete the input, and the key to the long keyboard, the fingers need to force some. What kind of keyboard is required, which is based entirely on the user's usage habits, that is, feel. However, after pressing the key, can not quickly restore to the original position, that is, the keys of the rebound is not enough products will increase the user's fatigue level.

Small knowledge: Resilience refers to the key cap in the keystroke when the damping, reaction to the user there, is the feeling of the keyboard button press down to come back very slowly.

Resilience is closely related to the key process, and the different key processes have the resilience to fit it. If the rebound is too strong, it will increase the strength of the keystroke, if the rebound is too weak, then the keystroke will have a loose feeling. The resilience and the key process design is reasonable, can make up to a large extent the keyboard because the key is short to bring the problem of feel.

Ergonomic keyboard with key combination to improve work efficiency

The function of the keyboard is input, the user can input the letters they need into the system and display it on the computer screen. In fact, the keyboard is not just a text input tool, in some special occasions, the use of keyboard keys are often more prominent than the mouse. Below to introduce some key combinations, using these key combinations can improve work efficiency.

Quick Start program with key combination

There are many ways to open applications on your desktop. For example, you can double-click to open, you can use the mouse to select, and then use the keyboard on the "Enter" key to open, if you want to return to the innocence of the era without the mouse, you can also use the TAB key to switch to the appropriate program, and then use "Enter (enter)" Key Open. Of course, you can also override all the mundane ways of setting shortcuts to applications on the desktop. For example, to the QQ application set a shortcut key, right click on the desktop QQ icon, and then select Properties, "Shortcut" in the "shortcut" type you want to set the shortcut keys, and then click "Apply" can be. Note that some of the keys that are prone to conflict, such as numeric keys, are set to shortcut keys, and the system automatically sets the shortcut key to "ctrl+alt+ number keys."

Combination of keys to help you take a screenshot

"PRTSCR" key is the interception of screen graphics key, is a lot of users usually use the shortcut keys. But it intercepts the whole display of the current image, if I only need a screenshot of the window, not to intercept first, and then in the "paint" in the screen interception? It's not so troublesome to use the "ALT+PRTSCR" key combination to intercept only the image of the currently active window. The keyboard in the daily use, in addition to affect the text worker, will also affect the game player's game.

The Mystery of drift

Today there are a large number of specialized keyboards for individual games, such as the Zboard series "World of Warcraft" special Keyboard, "DOOM3" Special Keyboard, a large number of Korean star players using the Samsung DT35 keyboard, although the game in the design of the operation is very good, but the price is very expensive.

In recent years, the emergence of a large number of network leisure games, in fact, the hardware requirements of the computer is not high, but the mouse, keyboard requirements are relatively high. In fact, for the average player, a dozens of yuan money, hit the feel good keyboard, plus some settings, the game, will not be more than those dedicated keyboard poor. The following is a casual racing game "running Kart" as an example, in the registry of the keyboard delay and reaction speed set to improve everyone in the game to run out of the opportunity to drift.

In the system "run" type "Regedit" command, enter the registry, pull down the second column of "HKEY_CURRENT_USER", and then open the following "Control Panel", click "Keyboard", the right will appear 4 items, the last two " Keyboarddelay "and" Keyboardspeed "are the keyboard's latency and reaction speed values. The default values for these two items are 1 and 31, and a lot of "running kart" Masters set them to 0 and 48. 48 is also only the master according to their own practice set out the numerical value, this value is different from person to person.

The above settings are in the system registry, that is to say, this setting can also be applied in other online games, such as "Jin Dance Troupe", "Jin Band" and "Street basketball", can also be set accordingly. Of course, set the specific value depends on the actual operation.

Conclusion

The application of the keyboard is actually very simple, when you are on the keyboard when the fingers fly, have you ever thought of the key between the gap between the gaps hidden bacteria harm you? It is not enough to use a good keyboard, but also to know how to love it. Of course, the more fragile mouse, should also be a variety of care.
