The SCnnn notation, where nnn is the scancode of the key, allows us to work with other keys not mentioned above. See below for more details.

VKnn can be written, where nn is the hexadecimal virtual key code. Despite the fact that this rarely used method is supported by all versions of the program, only from version 1.0.38.02 and higher, for some types of hotkeys, it is implemented to prevent them from being tracked by the "keyboard hook" function (keyboard interrupt handler). For example, the following key combination does not use a keyboard hook, and as a result can be invoked by pressing both the Home key and the NumpadHome key:

^ VK24 :: MsgBox You pressed Home or NumpadHome while holding down the Control key.

Joystick

Joy1 - Joy32: Joystick buttons. For the convenience of determining the numbers of the buttons of your joystick, a special test script was created (see the link in the original article). Note that prefixes such as ^ (control) and + (shift) are not supported here (however, the GetKeyState command can be used). Also note that joystick keystrokes are always directed directly to the active window that supports receiving such signals.

Although the following joystick controls cannot be used as hot keys, they can be used using the GetKeyState command:

JoyX, JoyY, and JoyZ: where X (horizontal), Y (vertical), and Z (height / depth) are the joystick coordinate axes.

JoyR: joystick steering wheel or 4th axis of joystick.

JoyU and JoyV: 5th and 6th axis of the joystick.

JoyPOV: the point-of-view (hat) control (POV control, "hat" or "view switch"; for example, the view from the player's eyes).

JoyName: the name of the joystick.

JoyButtons: the number of buttons supported by the joystick (not always accurate).

JoyAxes: The number of directions supported by the joystick.

JoyInfo: generates a string of zero or more characters to illustrate the capabilities of the joystick: Z (there is a Z direction), R (there is an R direction), U (there is a U direction), V (there is a V direction), P (there is a POV control), D (POV control has a limited number of discrete / intermediate settings), C (POV control transmits continuous / accurate data). Example string: ZRUVPD.

Multiple joysticks: If you use several joysticks at the same time, for more precise command addressing, use the joystick number before the name of the joystick key when writing. For example, the entry 2joy1 would represent the first button of the second joystick.

Note: if you have problems with the scripts detecting your joystick, you can try changing the number of the joystick from 1 to something else, even though you only have one connected to your computer. It is not known for what mystical reasons, but sometimes this together with the use of our test script gives a positive result.

Using the joystick as a mouse: a special script turns your joystick into a mouse (see the link in the original article).

Remote control panels

Receiving signals from remote control panels using a special client script WinLIRC - see the link in the original article.

Special keys

If your keyboard or mouse has keys not listed above, you can still use them as hotkeys using the following method:

First, make sure you have the keyboard hook #InstallKeybdHook installed.

Run this script, and then double-click on its icon in the system tray to open its main window.

Then we press the very key that we are trying to define.

Next, open the "View - Key history and script info" script window menu and scroll through the entries to the very bottom.

Somewhere at the bottom of this log, there should be records on pressing-releasing our desired key. The log itself is updated by pressing the F5 key. Note: if after pressing the desired key no entries appear in the log, then this key is not recognized by this program. In this case, you cannot use this key as a hotkey, because either your keyboard driver or its hardware component itself gives a signal that is too low for AutoHotkey to handle. In the case of "evil" drivers, you can try either reconfiguring the "native" drivers themselves, or replacing them with more friendly ones, such as the default Windows keyboard drivers.

If your key was successfully identified, pay attention to the three-digit hexadecimal number in the second column of the log (for example, 159).

Now, to use this key as a hotkey, follow this example:

SC159 ::; Replace 159 with your key index. MsgBox, you pressed the% A_ThisHotKey% Return

how alternative way or in addition to the above: to reassign any key to our "desired" key, use the notation like #c :: Send (vkFFsc159)... Replace 159 with your key index determined by the above method. If necessary, replace the letters FF with the ones displayed in the first column of the "View-Key history" log (your virtual key code).

Not every user knows what all the keys on a PC keyboard are for. But among them there are many necessary and unused buttons. To learn how to use them more effectively, 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 they are for additional keys, and then completely forgets about them, using only those that allow you to type text. 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 your work on the computer and make the process more efficient. Thanks to the use of additional buttons, the user can quickly type text, draw up a report, or simply switch between windows.

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

1. Function keys (F1-F12) are designed to perform special tasks and cancel the called action when pressed again. For example, F1 is pressed to invoke the help of a 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 symbols used when working on a PC.

3. Control keyswhich 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 the browser, or when selecting files on a computer.

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

6. Number keys are needed in order to quickly enter numbers, therefore they are often used when writing reports or working in a calculator.

7. Editing keys (deleting information) - Backspace, Delete.

The location of the keys on different keyboards may differ, 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 navigate 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:

Space bar located at the bottom of the keyboard and is the largest. When typing, it makes a space between words, and when a text fragment is selected, it replaces it with a space, which speeds up work in text editor... Scrolls down in an Internet browser.
Esc when pressed, cancels the last action, closes or minimizes open windows.
Print Screen creates a screenshot that is inserted into text and image editors. The resulting image is called a "screenshot". The key is also used to print the screen image.
Scroll Lock is needed to enable the mode in which you can scroll the page up and down with the cursor keys. But it doesn't work on all computers.
Pause / Break pauses a running process, for example, when the computer boots up, you can pause and see system information, but like the previous described key 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 denoted 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 moves 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 turns the page up. In some media players, pressing the key plays the previous file in the folder.
Page Down scrolls down the page, and in players includes the media file next in the play queue.
Backspase is used to delete characters to the left of the cursor in a text editor or in a character input 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.
Caps lock switches uppercase letters to uppercase letters and vice versa.
Shift capitalizes a letter when pressed at the same time. If Caps Lock is on, 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, you will switch to the program window that was open before.
Num lock turns on the mode in which additional numeric keys work.
Enter is needed to go 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.
Context is 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.

Hot keys speed up the work at the computer, causing one or another action. In the combinations described, the keys are clamped in the order in which they are written. Using a combination of buttons, 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 you change faster account user.
Windows + D - Minimizes all windows. To open them, the keys are pressed again.
Windows + Space - the combination is meant to show the desktop.
Windows + E - needed to go to "my computer".
Windows + R - Opens the Run window.
Windows + Tab - switch between windows running programs.
Ctrl + Shift + Esc - Opens the Task Manager.
Win + F - opens a search window file system computer.
Ctrl + F - activates the search function in the document or in the program.
Alt + F4 is a keyboard shortcut that closes the active window. If the desktop is active, allows you to restart or shutdown the computer when pressed again.
Ctrl + - zooms in or out depending on which direction the mouse wheel is scrolled in.
Alt + Print Screen - the combination creates a screenshot of the window of the program that is active at this moment.

Hotkeys when working with text and files

Ctrl + A - selects all characters in a text editor or files in open folder.
Ctrl + C - copies the selected fragment 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 running at that moment.
Ctrl + S - saves 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 hard to get used to if you have to use multiple 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 multiple keys, comparing the feel. Some devices click too loudly during use or are pressed harder. 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 are short. 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 you should choose just such models for long-term work.

Important! For comfortable work, it is worth purchasing white keyboards. If the 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 the job, it is important to create a comfortable environment. To do this, the arms must be in a comfortable position. Do not forget about posture. Choosing the right keyboard and observing 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 make the most of them.
