Purpose of each key on the computer keyboard. Special keys on the keyboard

regular keyboard can be roughly divided into several areas.

The topmost area of ​​the keyboard contains keys that are not used to enter data into the computer. These keys perform auxiliary actions, which are shown in the table below.

Esc key - this key is used to cancel an action, exit programs, games, exit applications, etc.

Esc Key Functions .

Its main function is to cancel the team that was ahead. If you right-click to open a menu on the desktop or on the taskbar and then press the Esc key, the menu will immediately close. If you start playing a game and accidentally press the Esc key, you will almost always exit that game. But by pressing this key again, you will return to your game again.

When you are on the Internet, you enter the next site address, and then accidentally press the Esc key, you will immediately return to the previous site address that you have already considered.

In the top row of the keyboard are function keys (limited by a red rectangle in the picture).

Function keys FI-F12 designed to perform certain actions assigned to them. Actions depend on programs running in this moment on a computer, but usually the F1 key use to call help system currently running program. If a program is running, help about that program appears.

"F3" Calls up a search box.

"F5" Reloads an open browser page.

F8 Booting the computer while pressing this button makes it possible to work in safe mode operating system.

The actions of the remaining function keys with the F symbol are mostly possible in combination with modifier keys and may vary depending on the make and model of the computer. If the actions of any key on the keyboard of your computer differ from those described here, then you can find out about its purpose in the user manual.

Pause/Break . When the computer is booting, it allows you to put the computer "on pause" - to suspend the boot process.

Functions of the Pause/Break key. While doing Windows boot, at first you see information appearing on the monitor about your computer, about the hard disk, about the status random access memory, about all the components. The information displayed on the monitor appears and disappears quite quickly and it is extremely difficult to comprehend it. Here, to get the opportunity to deal with it, you just need to press the "PAUSE" button. And to complete the process of loading the operating system, you must press any button on the keyboard. Sometimes used by some programs.

Key " Print Screen/SysRq".

Pressing this key allows you to take a screenshot of your monitor. When this key is pressed, and it is in the picture in the red frame, at the moment it is pressed, the image that is currently on the monitor is stored in the computer's memory. Next, we take the saved image from computer memory using a conventional graphic editor, you can graphic editor"Paint", which is already built into the operational Windows system. If you use the “Alt+PrintScreen” key set, then you only take a photo active window but those are completely full screen. In the picture, the Alt keys are framed in blue.

Key switches the mode of displaying information on the display screen, in which pressing the cursor keys moves the screen itself, and not the cursor. When you press this button, the indicator light will immediately turn on. By using this key to control the cursor, you can move the screen image. This feature is used in Microsoft Excel, Lotus Notes. This is especially evident in Excel program. It can be used to scroll through text, although it is more convenient to do this with the mouse wheel. Other programs use ScrollLock to special functions, for example, in Opera browser the key is used in combination with numbers to switch voice signals. Currently, this key is practically not used, so there are keyboards where it is not.

Shift key. Simultaneously pressing this key and a character key allows you to temporarily switch to the uppercase (capital) letter input mode, or enter another character located on the same key. There are two such keys on the keyboard - left and right, and in some programs their action is different. For example, to enter a capital letter "And" you need to press the Shift key and without releasing it, press the AND key.

Tab key It is indicated by an icon in the form of two opposite arrows and pressing it indents from the beginning of the line - a paragraph. Allows tabulation - horizontal alignment of characters. The tab character is eight regular characters. Tabs are used when creating text documents. Designed to move the cursor:

1. when editing texts, it is used to move to the next tab stop, i.e. move the cursor several positions forward;
2. in dialog boxes, jumps to the next query field;
3. in a table, moves the cursor to the next cell.

In other programs, its purpose is to switch between windows on the screen.

Below it is CapsLock key. Pressing this key fixes the spelling capital letters. When pressed again, they write again capital letters. This mode is indicated by the indicator light on the right upper corner keyboards. Pressing again cancels the mode. When CapsLock is on, pressing a key enters lowercase letters.

Num lock key turns on and off the numbers located on the right side of the keyboard. If the keyboard is enabled, you can use it to enter numbers and arithmetic.

When enabled, this mode is also displayed by an indicator in the upper right corner of the keyboard, signaling that additional keyboard at work. Now, in addition to entering numbers from the main keyboard field, they can also be entered from the additional one. True, those characters that are printed on the keys of the additional keyboard simultaneously with numbers will not work.

In most cases, the described keyboard fields are enough for work, but for those who like to work with a compact digital and control keyboard"a la calculator" there is another additional field of keys - the rightmost. This field is called that - an additional keyboard, in contrast to the main keyboard field.

When you press this block of keys with the designation of numbers, the numbers are printed, but with one condition - when the "NumLock" key is turned on. Numeric keys when the NumLock key is off, they perform the functions of a different plan. The “End” key is duplicated by pressing the “1” key on the main keyboard and the “Home” key is duplicated by the “7” key also on the main keyboard.

If the "insert" mode is on, then when you type, between two words the right word will move to the right, and the text you enter will move the words apart and be printed between them. In this mode, the text seems to be inserted and moves the entire end of the phrase to the right.

But with the “replacement” mode, if you insert a word between two words, then the word located on the right is replaced by the word that you insert .;

1. in programs like Total Commander objects are selected.

If you press the Inset key, the text will be printed on top of what is printed, while erasing the latter. If you press this key again, this action will be terminated.

Framed with blue color the "Insert" key, which is located on the numeric keypad, together with the number "0" works only when the "NumLock" key is turned off.

Notebook keyboard features.

Since a laptop keyboard, by definition, should take up little space, many functions are “hidden” on it. And in order to find them, there is magic key . It is not found on all types of keyboards, although it is almost always present on laptops. It is usually located in the lower left corner of the keyboard, but there may be other options, there are no standards here. Key inscription highlighted in color (most often blue) or surrounded by a frame. On those keys that work in conjunction with , inscriptions or symbols are applied that have the same color as the inscription on the key , or they are also framed.

Lettering or symbols that have the same color as , activated when combined + (key), i.e. while pressing and holding the key we press the key where the function we need is shown in a stylized form. Combining this key with function keys (keys on the top row of the keyboard) changes the basic actions of these keys. So, combining it with the F1 key puts the computer (laptop) into sleep mode;

• with F2 - turns the adapter on and off wireless communication(wifi);
• with F3 - opens the mail program;
• with F5 - reduces the brightness of the monitor;
• with F6 - increases it;
• with F7 - turns the monitor on and off;
• with F10 - enables and disables the built-in speakers;
• with F11 - lowers the volume of the speakers;
• with F12 - increases it;
• the screen brightness is increased by the key where there is a “big sun” (there may be a “sun” icon in combination with the “increase” icon);
• decrease - on the contrary, the one where the “small sun” (or maybe the “sun” icon in combination with the “reduce” icon);
• keys with the “loudspeaker” icons in combination with the “more” or “less” icons - increase / decrease the volume;
• crossed out mouse - turn off / on the TouchPad;
• crossed out loudspeaker - mute / unmute the sound, etc.

Actions when combining function keys with the Fn key may differ depending on the different types keyboard, so you can clarify them in the user manual of the device, or be guided by the icons (usually of a different color) located on the keys next to or below its main value.

Look carefully, slowly, at the keyboard of your laptop, put the instructions attached to it nearby, spend some time mastering all these wonders and they will become familiar to you.

I think you understand, because I have a “beech” of just such a brand. And also because after acquiring a computer from this company, I ran on the Internet for a long time to find information on the functionality of its keyboard.

There is no description of this topic in the instruction manuals for these laptops. Maybe they think that this is not so important, but I have a different opinion, and frankly I “miss” the good old days when, together with consumer electronics, "went" tolmud on operation and, identifying the most frequent breakdowns and their reasons.

For clarity, I made a picture that clearly shows all those keys that we will talk about.

• Fn + F1-Putting the computer into sleep mode and returning to working condition.
• Fn + F2-Turns on / off network adapter wireless network wifi laptop.
• Fn + F5-Decreases the brightness of the monitor.
• Fn + F6-Increase the brightness of the monitor.
• Fn + F7-Turn on turn off the monitor.
• Fn + F8-Gives you the ability to switch to an external display, while the display can be enabled on both at the same time or only on one.
• Fn + F9-Turn off / on the touchpad (touchpad), touch screen to use a laptop without a mouse.

Other keys for sound control:

• Fn + F10-Turn off the sound.
• Fn + F11-Reduce the sound.
• Fn + F12-Increase the sound.

Also on the keyboard there are two more important buttons, they are in the penultimate row, if you count from the bottom.
These are also special function keys:

1. Fn + V - designed to enable / disable the built-in webcam of a laptop.
2. Fn + C - Which controls another important function, and the “Splendid Video Intelligent Technology” itself.

This technology allows you to improve the image on the screen laptop, depending on specific conditions
work.

Thus, we have considered "special" keyboard function keys Asus laptop .
But in order for all these buttons to work, you need to install the driver package, included with this and other laptop computers.
On this positive note, I want to end this interesting and necessary topic, but I also “have to invite YOU to read” about that. And for those to whom this information has become useful, then leaving do not forget to press the twitter button. So that your friends can get this knowledge. Bye Bye.

And what is needed for? You already know. Now we need to talk about the purpose of the keyboard keys. After all, the keyboard, figuratively speaking, is an intermediary between you and the computer, a tool for interacting with smart assistant. By pressing the keys, you send commands to the computer to be executed.

Hence the conclusion: when you know the purpose and key combinations, working on a computer becomes easier and more enjoyable.

Key assignment:

— service key performs a stop or cancel last action. For example, if the web page for a long time is downloading, you can press ESC to stop the download.

F1—F12. reserved for specialized functions in programs. Therefore, the execution of the function in different programs may differ. For example, the F5 key in a text Microsoft editor Word, performs the "Find and Replace" function, and file manager Total Commander, the same key performs the "Copy" function. But we can say with certainty that the key F1 opens file in all programs Reference.

Tab used to create indents ( Red line) in word processing programs. Also, if you are filling out tables or forms, you can use the Tab key to move to the next field.

- performs the function of changing the case (CAPITAL LETTERS). When you press this key, the indicator above the numeric keypad lights up, further typing will be done in capital letters. Pressing this key again will disable the mode. Capital letters”, the indicator above the numeric keypad goes off.

Shift- function keys are used in conjunction with other keys. As you can see, the keyboard has two shift keys, left and right. The purpose of these keys is exactly the same, and their location on the keyboard is due to the convenience of typing. blind printing method.

Now I’ll explain, say, when you are typing and you need to put Exclamation point, most conveniently with the little finger right hand hold the shift key, and press the 1 key with the little finger of your left hand. More shift key participates in many key combinations, for example, entering a capital letter, punctuation, performing specialized program functions, and so on.

Control (Ctrl), Alternate (Alt) Control keys are designed to work in combination with other keys. Typically, you hold down the Ctrl key, Alt key, and then press another key to execute a specific task. For example, in many programs, the combination ctrl+s- save the file.

The main part of the keyboard includes alphanumeric key set (letters and numbers) and space.

Enter- confirmation of the action. For example, while on the internet, you can enter a website address and then press the Enter key to go to the website. It is also used to start newline in text editors. Enter on the numeric keypad has the same purpose and is often used when executing mathematical calculations, say, in the "calculator" application to get the result.

- in text editor erases the characters to the left of the cursor. And in the browser allows you to return to the previous page.

Delete(Del) in a text editor, erases the characters to the right of the cursor. Performs the delete function in file managers.

— enable/disable the "insert-replace" mode. The key is practically not used, but it can play a cruel joke. If you accidentally press this key while working in a text editor, you will switch it from "insert" mode to "override" mode. After that, if you make a mistake in a word, you will want to correct it. After correcting the error, you will find that the character to the right of the cursor has disappeared! You will try to enter it again, but the next character to the right of the cursor will disappear. So it will be until you press the insert key again. Not knowing about this key, some people, due to one typo, retyped the entire remaining text.

Keyboard shortcuts

A key combination is when you hold down one or two keys and briefly press a third. For example, Ctrl+S, where the plus indicates a key combination. That is, you press and hold the Ctrl key, and then briefly press the S key. The plus in this notation is used to indicate a key combination and is not pressed in its execution.

The designation of keys on a computer keyboard has its own functional features and purpose. Using the keys, you can control the computer, write texts, enter numerical data. The designation of the keys on the keyboard is divided into four groups of keys:

Alphabetical - digital, basic, there are most of them on the keyboard. They are located in its central part and are intended for a set of numbers, letters, punctuation marks and various symbols.

Function keys from F1 to F12 are located at the very top of the keyboard. Each of these keys has a defined function and it depends on what program you are currently working with. For example, when you press the F1 key, you will always get background information about this program.

The most famous keyboard shortcuts

The side numeric keypad is designed for fast entry numbers, but before that we need to press the "Num Lock" key. When it is disabled, the keys are used to control the cursor and the screen. The keys of this group are grouped and located in the form of a block, as on a calculator or adding machine.

The cursor and screen control keys (arrow keys) are used to move the text entry cursor, set a pause, and take screenshots from the monitor screen. Here I will add a little clarification text cursor appears when you enter text and indicates where you will start typing. In addition, arrow keys are commonly used to control a computer, to navigate web pages, documents, and in computer games.

Now let's take a closer look at the designation of the keys on the keyboard:

Scroll-Lock Disables scrolling text mode

Pause Suspends the execution of some programs and the loading of the operating system

Hello to all blog readers. Tell your friends, have you ever wondered what great functionality the keyboard is fraught with? Most people do not even suspect that with its help you can perform actions that can facilitate and. Isn't it sad that application developers sit and write commands for hours every day that assign useful functions to key combinations, and only a few use these combinations.

So, it seems to me that the time has come to correct this oversight, so that it would be easier to work, and the work of the developers was not in vain. In this article I will try to analyze in detail how to use the keyboard on a laptop. Agree, not everyone knows what, for example, the “pg dn” button is needed for. But there are still a lot of such buttons, and they all carry some kind of useful feature. Here are exactly what functions they conceal, we will understand today together. For clarity, I have posted below two photos with keyboards: with and without a number pad. They are most often found in laptop designs.

Keyboard with numeric keypad

Keyboard without digital block

Entering text information

Entering Numeric Information

Any keyboard contains numbers in the top row, but typing numbers from it is not always convenient. It is more customary to work with the layout of the buttons as on a calculator, so the keyboards have an additional number pad.

The first step is to learn how to turn on the number pad, although it’s worth saying right away that it doesn’t happen in all laptop models, but now it’s already rare and, as a rule, it costs almost every laptop computer.

To better understand how to include numbers, we will use two keyboards from different laptops (for clarity), one with a built-in Numpad, and the other without it.

1. A laptop with a digital block (see the picture at the beginning of the article). In order for it to be activated, click on "Numlock".
2. A laptop without a digital block (picture below).

If you don’t have it, then you can use the additional one, although this was provided for by laptop manufacturers. When enabled " Numlk"on a laptop keyboard without a separate number block, certain symbolic keys begin to play its role. On the next photo- you can see it.

The red circles show what will be printed on the screen when " Numlk».

On keyboards, the digital block enable mode is usually signaled LED indicator. Try pressing the button Numlk" or " Num Lock»Watch which indicator indicates this mode on your keyboard.

Function keys

This section will be completely devoted to an overview of the main function buttons that are used in the computer, and we will also talk in detail about the purpose of these keys.

Scroll lock

This button is almost never used today. at least I have. When disabled, it does not perform any functions other than changing the position of the cursor, and when enabled, it makes the mouse cursor move the screen itself, for example, moves the page in the browser without any clicks.

Break

When transferring from of English language it can be understood that main function this button is to stop or cancel some action.

"Insert"

She is also on the stage of extinction, as the combination "Ctrl + C" and "Ctrl + V" has long been used instead. Perhaps you have already guessed about its function, and if so, then its function was to copy and paste files, folders. Most often it is used together with "Ctrl" and "Shift". If used together with the first key, then the “copy” command will be produced, and if used together with the second key, the “paste” command will be initialized.

fn

Now let's talk about the button, which today is one-stop solution for all laptops. Its essence lies in the fact that when combined with different keys able to turn on and off different hardware parts of the laptop and change their states. Best of all, its functionality is noticeable in combinations with f1 ... f12. Take a closer look at the icons next to the names of these keys, they are highlighted in the same color as the "Fn" button. With the help of them you can understand what will happen when used together with "Fn".

Below is a series of function buttons with icons, on your laptop they may be different. Let's take a look at their purpose.

Pressing together with the key " fn":

• F1 - enable or disable computer sleep mode
• F2 - enable or disable WiFi module on a laptop
• F5 - decrease the brightness of the monitor screen
• F6 - increase the brightness of the monitor screen
• F7 - disable monitor
• F8 - switch display modes between laptop monitor and external device- second monitor or projector
• F9 - disable the touchpad, when using computer mouse
• F10 - mute
• F11 - decrease the sound volume
• F12 - increase sound volume

"Page up" and "Page down"

Translated from English, “page” is a page, and “up, down” is up, down. These buttons are used to scroll the visible part of the screen exactly to the height of the application window being viewed in the operating system. But today, the mouse wheel is more commonly used for this purpose.

Win

This button on the keyboard is presented in the form of a logo, a flag in a circle. Also referred to as "win". Used to activate the start menu, which in turn serves as one of the ways to start different kind programs. Also in some applications it is used in combination with others, in order to activate or start some kind of additional option, function.

For example, Win + L - blocks the computer. You must enter a user password to continue working.

Del

I think it’s not worth talking a lot about the “del” button, that is, “delete”, since it’s immediately clear that it is used to delete different files and folders.

Some keys have been omitted, such as "Ctrl", "Alt" and "Tab" due to the fact that they are ordinary keys for combinations and in themselves any important functions do not fulfill. Although "Tab" does different functions: switch between items in the windows of the system, tabulation in word processor. But for all the time that I use a computer, I rarely used it, only "Alt" + "Tab" - switching between windows.
