What do you need to press on the keyboard to. Assignment of keyboard keys. Keyboard shortcuts for working in Windows Explorer

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 a 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 stops or undoes the last action. For example, if a web page takes a long time to load, 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 the Microsoft Word text editor performs the Find and Replace function, and in the Total Commander file manager, 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 will explain, say, when you are typing text and you need to put an exclamation mark, it is most convenient to hold the shift key with the little finger of your right hand, and press the 1 key with the little finger of your left hand. The shift key is also involved in many key combinations, for example, entering a capital letter, punctuation mark, execution of specialized functions of the program, 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 perform 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 a new line in text editors. Enter on the numeric keypad has the same purpose and is often used when performing mathematical calculations, say in a calculator application to get a result.

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.

The main device for manual input of information, commands and data. This article discusses the keyboard layout, layout, key assignment, symbols and signs.

Computer keyboard: principle of operation

The basic functions of the keyboard do not require special software. The drivers required for its operation are already available in the BIOS ROM. Therefore, the computer responds to the commands of the main keyboard keys immediately after being turned on.

How the keyboard works:

After pressing a key, the keyboard chip generates a scan code.
The scan code enters the port integrated into the motherboard.
The keyboard port tells the processor a fixed interrupt number.
Having received a fixed interrupt number, the processor turns to special. area of RAM containing the interrupt vector - a list of data. Each entry in the data list contains the address of the program serving the interrupt, which matches the entry number.
Having determined the program entry, the processor proceeds to its execution.
The interrupt handler program then directs the processor to the keyboard port, where it finds the scan code. Further, under the control of the handler, the processor determines which of the characters corresponds to this scan code.
The handler sends code to the keyboard buffer, notifying the processor, and then terminates.
The processor moves to the pending task.
The entered character is stored in the keyboard buffer until it is picked up by the program for which it is intended, for example, the Microsoft Word text editor.

Photo of a computer keyboard and key assignment

The standard keyboard has more than 100 keys divided into functional groups. Below picture is shown - photo of computer keyboard with a description of the key groups.

Alphanumeric keys

The alphanumeric keys are used to enter information and spell commands. Each of the keys can work in different registers, as well as denote several characters.

Switching the case (inputting lowercase and uppercase characters) is carried out by holding the Shift key. For hard (permanent) case switching, Caps Lock is used.

If the computer keyboard is used to enter text data, the paragraph is closed by pressing the Enter key. Next, data entry starts on a new line. When the keyboard is used to enter commands, Enter terminates the input and starts its execution.

Function keys

Function keys are located at the top of the keyboard and they consist of 12 buttons F1 - F12. Their functions and properties depend on the running program, and in some cases the operating system.

A common function in many programs is the F1 key, which calls up help, where you can find out the functions of other buttons.

Special keys

Special keys are located next to the alphanumeric group of buttons. Due to the fact that users often resort to using them, they have an increased size. These include:

Shift and Enter discussed earlier.
Alt and Ctrl are used in combination with other keyboard keys to form special commands.
Tab is used for tabulation when typing.
Win - opens the start menu.
Esc - refusal to use the started operation.
BACKSPACE - delete the characters just entered.
Print Screen - print the current screen or save a snapshot of it to the clipboard.
Scroll Lock - switches the operating mode in some programs.
Pause/Break - pause/interrupt the current process.

Cursor keys

The cursor keys are located to the right of the alphanumeric pad. The cursor is a screen element that indicates where information is entered. The arrow keys move the cursor in the direction of the arrows.

Additional keys:

Page Up/Page Down - move the cursor one page up/down.
Home and End - move the cursor to the beginning or end of the current line.
Insert - traditionally switches the data entry mode between insert and replace. In different programs, the action of the Insert button may be different.

Additional numeric keypad

The additional numeric keypad duplicates the actions of the numeric and some other keys of the main input panel. To use it, you must first enable the Num Lock button. Also, additional keyboard keys can be used to control the cursor.

Keyboard shortcut

When a certain key combination is pressed, this or that command is executed for the computer.

Frequently used keyboard shortcuts:

Ctrl + Shift + Esc - Open Task Manager.
Ctrl + F - search box in the active program.
Ctrl + A - Selects all content in the open window.
Ctrl + C - copy the selection.
Ctrl + V - paste from clipboard.
Ctrl + P - print the current document.
Ctrl + Z - cancel the current action.
Ctrl + X - cut the selected section of text.
Ctrl + Shift + → select text by words (start at cursor position).
Ctrl + Esc - Opens/Closes the Start menu.
Alt + Printscreen - screenshot of the active program window.
Alt + F4 - closes the active application.
Shift + Delete - permanent deletion of the object (past the trash).
Shift + F10 - call the context menu of the active object.
Win + Pause - system properties.
Win + E - launches the explorer.
Win + D - Minimizes all open windows.
Win + F1 - Opens Windows Help.
Win + F - Brings up the search box.
Win + L - lock the computer.
Win + R - open "Start the program."

Keyboard symbols

Surely, many users have noticed symbols for nicknames and other social networks. How to make symbols on the keyboard if there are no explicit keys for this?

You can put characters on the keyboard using Alt-codes - additional commands for entering hidden characters. These commands are entered by simply pressing the Alt key + a decimal number.

You can often find questions: how to make a heart on the keyboard, an infinity sign or a euro on the keyboard?

alt+3=
Alt+8734 = ∞
Alt + 0128 = €

These and other symbols on the keyboard are represented in the following tables in the form of figures. The "Alt code" column contains a numeric value, after entering which, in combination with the Alt key, a certain character will be displayed. The character column contains the final result.

Please note that if the optional numeric keypad is not enabled - Num Lock is not pressed, then the Alt + number key combination may lead to unexpected results.

For example, if you press Alt + 4 in the browser, without Num Lock enabled, the previous page will open.

Punctuation marks on the keyboard

Sometimes users, when trying to put a punctuation mark on the keyboard, do not get exactly what they expected. This is due to the fact that a different keyboard layout implies a different use of the keyboard shortcut.

Below is how to put punctuation marks on the keyboard.

Computer keyboard layout

Computer keyboard layout- a scheme for assigning symbols of national alphabets to specific keys. Switching the keyboard layout is performed programmatically - one of the functions of the operating system.

On Windows, you can change the keyboard layout by pressing Alt + Shift or Ctrl + Shift. Typical keyboard layouts are English and Russian.

If necessary, you can change or add the keyboard language in Windows 7 by going to Start - Control Panel - Clock, language and region (sub-item "change keyboard layout or other input methods").

In the window that opens, select the "Languages and keyboards" tab - "Change keyboard". Then, in the new window, on the "General" tab, click "Add" and select the desired input language. Don't forget to save your changes by clicking OK.

Virtual computer keyboard

Virtual keyboard- a separate program, or an add-on included in the software. With its help, letters and symbols are entered from the computer screen using the mouse cursor.

The virtual keyboard is needed, for example, to save confidential data (login and password). When entering data using a regular keyboard, there is a risk of information being intercepted by malicious spyware. Then, through the Internet, the information is transmitted to the attacker.

You can find and download a virtual keyboard using search engines - this will not take you much time. If Kaspersky Anti-Virus is installed on your PC, you can launch the virtual keyboard through the main program window, it is included in it.

Screen keyboard

Screen keyboard located on the touch screen of a smartphone, pressing on it occurs with the user's fingers. Sometimes it is called virtual.

To launch the On-Screen Keyboard in Windows 7, go to Start - All Programs - Accessories - then Ease of Access - On-Screen Keyboard. It looks like this.

To switch the keyboard layout, use the corresponding buttons on the taskbar (near the date with time, at the bottom left of the monitor screen).

What to do if the keyboard does not work

If your keyboard suddenly stops working - do not rush to get upset, first find out what caused the breakdown. All the reasons due to which it does not work can be divided into hardware and software.

In the first case, if the keyboard hardware is broken, it is very problematic to fix the problem without special skills. Sometimes it's easier to replace it with a new one.

Before saying goodbye to a seemingly faulty keyboard, check the cable with which it is connected to the system unit. It may have moved away a little. If everything is in order with the cable, make sure that the failure is not caused by a computer software failure. To do this, restart your PC.

If, after a reboot, the keyboard does not show signs of life, try to shake it up using the solution available in Windows. The sequence of actions is given on the example of Windows 7, if you have a different version of the Windows operating system, proceed by analogy. The principle is about the same, the names of the menu sections may differ slightly.

Go to Start - Control Panel - Hardware and Sound - Device Manager. In the window that opens, if you have problems with the keyboard, it will be marked with a yellow label with an exclamation point. Select it with the mouse and select Action - Delete from the menu. Close Device Manager after uninstallation.

Return to the "Hardware and Sound" tab and select "Add a device". After searching for hardware, your keyboard will be found and its drivers will be installed.

If the hardware installation was successful and the failure of the keyboard was due to a software failure, the Num Lock key light on the keyboard will light up.

If it was not possible to fix the problem, then a temporary solution may be.

These days, the computer keyboard, like the mouse, is considered a low-value device. However, she plays an important role in working with a computer.

Not every user knows what all the keys on a PC keyboard are for. But among them there are many necessary and not used buttons. To learn how to use them more efficiently, you should know the purpose of the keyboard keys and be able to use them at the right time.

Having started using a computer for the first time, a novice user does not think about what additional keys are for, and then completely forgets about them, using only those that allow typing. But additional buttons and their combinations can save time and, in some cases, money.

All keys are divided into 7 groups, each of which allows you to speed up the work on the computer and make the process more efficient. Thanks to the use of additional buttons, the user quickly types text, writes a report, or simply switches between windows.

Depending on the functions, the keys are divided into groups:

1. Function keys (F1-F12) are designed to perform special tasks and, when pressed again, cancel the called action. For example, F1 is pressed to bring up the help of the program whose window is active at the time of pressing. In games, the key performs the function that is assigned to it in the settings.

2. Alphanumeric are needed to enter numbers, keys, punctuation marks and other characters used when working on a PC.

3. Control keys, which include HOME, END, PAGE UP, PAGE DOWN, DELETE and INSERT.

4. Cursor keys are used to move the cursor while working in text-editing programs, in a browser, or when selecting files on a computer.

5. Control keys (modifiers) (Alt, Ctrl, Win, Caps Lock, Fn), used most often in combination with each other or with other keys on the keyboard.

6. Numeric keys are needed in order to quickly enter numbers, so they are often used when compiling reports or working in a calculator.

7. Keys for editing (deleting information) - Backspace, Delete.

The location of the keys on different keyboards may vary, but they are all located in approximately the same places relative to each other. Additional keys can also be built in to mute the sound, increase or decrease the volume, and quickly jump to the mailbox.

Let's take a closer look at the purpose of the computer keyboard keys with their full description.

Each key can perform one or more functions:

Spacebar located at the bottom of the keyboard and is the largest. When typing, it makes a space between words, and when a piece of text is selected, it replaces it with a space, which speeds up work in a text editor. In the Internet browser, it performs the function of scrolling down.
Esc when pressed, cancels the last action, closes or minimizes open windows.
Print Screen creates a screenshot that is pasted into text and image editors. The resulting image is called a "screenshot". The key is also used to print the image from the screen.
scroll lock is needed to enable the mode in which you can scroll the page up and down with the cursor keys. But it does not work on all computers.
Pause/Break suspends the running process, for example, when the computer boots up, you can pause and view system information, but like the previous described key, it does not work on all devices.
Insert activates the mode in which characters are entered over the typed. After pressing, it prints over the entered characters, which at this moment begin to be erased. To cancel the action, press the key again.
Delete is indicated on the keyboard as Del and is needed to delete entered characters in a text editor or selected files. If the action is performed in a text input field, it is removed to the right of the cursor.
Home this is the key that jumps to the beginning of the filled line. If the cursor is at the end of a sentence in a text editor, pressing the specified button will move it before the first letter in the line. If the click occurs on an empty line, nothing happens. In the browser, rewinds the page to the beginning (up).
end moves the cursor to the end of the line. In the browser, rewinds the page to the very bottom.
Page Up flips the page up. In some media players, pressing the key will play the previous file in the folder.
Page Down scrolls the page down, and in the players includes the media file that is next in the playback queue.
Backspace is used to delete characters to the left of the cursor in a text editor or in a character entry field.
Tab used to insert a tab character equal to 8 spaces (forms a paragraph, for example in Word). Also used in combination with other keys.
cap lock toggles uppercase letters to lowercase letters and vice versa.
Shift when pressed simultaneously with any letter, it makes it capital. If Caps Lock is enabled, it will be lowercase.
alt used in several keyboard shortcuts. Together with Shift, it changes the layout to English, if you press Tab simultaneously with it, it will switch to the program window that was open before.
Num Lock turns on the mode in which additional number keys work.
Enter needed to move to the next line in a text editor, as well as to enter information and confirm actions in many programs.
Windows is used to open the menu that is called when you click the Start button with the mouse.
Context located near the right key and calls the context menu, which differs depending on the program used.
The cursor keys move the cursor and allow you to scroll through pages in the browser.

Hotkeys speed up the work at the computer, causing one or another action. In the described combinations, the keys are pressed in the order in which they are written. Using button combinations, it is easy to speed up the process of calling a particular function.

Windows + Pause/break - Opens a window that displays information about the computer.
Windows + L is a combination that causes the computer to lock. It helps to quickly change the user account.
Windows + D - Minimizes all windows. To open them, the keys are pressed repeatedly.
Windows + Space - the combination is designed to show the desktop.
Windows + E - needed to go to "my computer".
Windows + R - Opens the Run window.
Windows + Tab - Switches between windows of running programs.
Ctrl + Shift + Esc - Opens the task manager.
Win + F - opens a search window for the computer's file system.
Ctrl + F - activates the search function in a document or program.
Alt + F4 is a keyboard shortcut that closes the active window. If the desktop is active, allows you to restart or shut down the computer when pressed again.
Ctrl + - Zooms in or out depending on which way the mouse wheel scrolls.
Alt + Print Screen - the combination creates a screenshot of the window of the program that is active at that moment.

Hot keys when working with text and files

Ctrl + A - Selects all characters in a text editor or files in an open folder.
Ctrl + C - copies the selection or files.
Ctrl + V - Pastes text or files contained in the clipboard.
Ctrl + Z - the combination is needed to undo the last action.
Ctrl + P - Opens the print window.
Ctrl + N - opens a new window of the program that is currently running.
Ctrl + S - saves the typed text or project.
Shift + Delete - the combination completely deletes files without placing them in the trash. Be careful and careful when using this keyboard shortcut!

Typing constantly on one keyboard is difficult to get used to another if you have to use several computers. In an electronics store, it is difficult to choose a specific model if you do not know what types of devices exist.

Depending on the buttons, all keyboards are divided into 3 types:

To find out which keyboard is more comfortable, try pressing several keys and compare the sensations. Some devices click too loudly during use or are pressed more hard. When pressed, it becomes clear to what depth the buttons are immersed.

In order not to get tired of the noise of the keyboard, for constant work, you need to choose models with softer keys. Standard devices have a long stride, while laptops have a short stride. This also needs to be taken into account.

A multimedia keyboard with additional buttons and connectors significantly increases the degree of comfort when working at a computer, so for long-term work it is worth choosing just such models.

Important! For comfortable work, it is worth buying white keyboards. If English and Russian letters differ in color, this allows you to quickly switch from one language to another.

Regardless of which keyboard is chosen for work, it is important to create a comfortable environment. To do this, the hands must be located in a comfortable position. Do not forget about posture. Choosing the right keyboard and following the basic rules of working at a computer will allow you to enjoy the process.

Friends! I hope this article was useful to you, and now you know the purpose of the computer keyboard keys and will use them as efficiently as possible.
