Laptop - how to use the keyboard. Assignment of computer keyboard keys
The keyboard is the main computer control tool. Mastering it is a top priority for any user. And having mastered the purpose of special keys and their combinations, you will be able to speed up and make your work easier.
Basic blocks of keyboard keys
A regular keyboard consists of 5 key blocks:
- Symbolic (with images of letters of the Russian and English alphabets, numbers and punctuation marks). To type characters instead of numbers, you must press and hold the Shift key.
- Additional block of numeric keys (on the right side of the keyboard). The Num Lock button is also located here, which turns this block on and off.
- Special keys:
- Caps Lock - changes the keyboard case (uppercase to lowercase). By default, most computers are configured to print in lowercase letters; after pressing the Caps Lock button once, capital letters are printed;
- Enter - usually used to move the blinking cursor to the line below;
- Tab - indents the “red” line;
- Alt, Ctrl - expand the capabilities of the keyboard; when pressed simultaneously with other symbols, they issue specific commands to the computer.
- Cursor control keys in graphic and text editors with arrows that move the cursor up, down, left, right. And also the buttons:
- Insert - allows you to activate the mode of inserting/replacing text on the page;
- Delete - deletes the character to the right of the text cursor or selected text;
- Backspace - deletes the character before the cursor;
- Home - moves the blinking cursor to the beginning of the text/paragraph;
- End - moves the cursor to the end of the page;
- Page up - turns the page up;
- Page Down - turns the page down.
- In addition, there are other keys:
- Esc - closes some programs (browser windows, computer games and others);
- long empty button - space;
- Print Screen - takes a “photo” of the screen and saves it to the clipboard.
- Function keys (top row, signed with Latin F and numbers from 1 to 12) - together with the previous block, allow you to use the keyboard without a mouse.
- F1 - call Windows Help;
- F2 - editing the selected object (renaming files, folders);
- F3 - search activation. Calls up a search window in the system or enables text search in the browser;
- F4 - activates the address bar in Windows Explorer and opens the address bar history in the Internet Explorer browser;
- F5 - executes the “refresh” command, for example, a page on the Internet or the operation of the system;
- F6 - moves the blinking cursor to the address bar of browsers or is used in computer games to save the achieved level;
- F7 - F9 - do not have standard functions, their purpose varies depending on the application. In games, F9 usually causes F6 to load a quick save;
- F10 - call the program menu;
- F11 - switches windowed mode to full screen and vice versa, this is convenient, for example, when watching movies;
- F12 - in the Microsoft Word text editor, allows you to save the current document.
In general, when getting acquainted with any application, it makes sense to understand what functions the function keys perform. This can help you make your work easier and faster.
"Hotkeys
Pressing certain keys at the same time allows the computer to quickly execute even more commands. Such keyboard shortcuts are usually called “hot”. The most common ones are:
- Alt+Shift - switch keyboard layout (changes input language);
- Alt+F4 - closes the current window;
- Alt+Ctrl+Del - opens “Task Manager”;
- Ctrl+A - executes the “select all” command;
- Ctrl+X - cut to clipboard;
- Ctrl+C - copy to clipboard;
- Ctrl+V - paste from clipboard;
- Ctrl+P - print the document;
- Ctrl+S - save the current document.
Features of working with a laptop keyboard
Those who have had to work on a laptop keyboard have probably noticed that some of the symbols and icons are different in color or framed. Also highlighted is the Fn button in the bottom row to the left of the space bar. When you simultaneously press Fn and keys of the same color, special tasks are performed.
This way you can change the sound volume and screen backlight, turn on/off the touchpad (touchpad), put the laptop into sleep mode and perform other actions. Which keys are responsible for a particular function depends on the laptop model and the manufacturer; this information can be found in the accompanying documents for the computer or by deciphering the icons.
The keyboard is used to enter information into the computer and provide control signals. It contains a standard set of alphanumeric keys and some additional keys - control and function keys, cursor control keys, as well as a small numeric keypad.
General concepts
Information entry point (cursor)- the symbol “|” flickering on the monitor screen, indicating the position in which the next character entered from the keyboard will be displayed.
The keyboard has a built-in buffer- small intermediate memory where entered characters are placed. All characters typed on the keyboard are immediately displayed on the monitor at the cursor position. However, if the system is busy, then the characters may not be immediately displayed on the screen, but placed in the keyboard buffer in order to display the entered characters on the screen after the system is released. If the keyboard buffer overflows, pressing a key will be accompanied by a sound signal, indicating that the character was not entered (rejected).
The most common today is 105(7) - a keyboard with a key layout QWERTY(read “querti”), named after the keys located in the upper left row of the alphanumeric part of the keyboard.
Alphanumeric keys
The alphanumeric keys of the keyboard are designed for entering English and Russian letters, numbers, punctuation marks and some other symbols. To change the input language, click in the indicator area Taskbars on the keyboard indicator icon and select the desired language.
The language can also be changed using the keyboard. To do this, you usually use one of two keyboard shortcuts: Alt (left) + Shift or Ctrl + Shift.
Alphanumeric keys also enter characters from other national alphabets. For example, if you have the Belarusian language installed on your system, then most of the letters of the Belarusian language coincide with the arrangement of the letters of the Russian language. But there are also differences. They are presented in the following table:
Function keys
At the top of the keyboard are 12 function keys. F1-F12. Function keys may have different meanings in different applications. Here is an example of the actions that the key performs F5.
Note that in many programs, the key is used to get help (hints). F1.
Control keys
Control keys have the following purpose:
Enter- enter key. In word processors, pressing the Enter key ends the paragraph entry. When working, for example, in a folder window or Conductor pressing the Enter key performs the same functions as double-clicking the left mouse button (usually the default action is open).
Esc(escape - exit) a key to cancel any actions, for example, to exit a dialog box, menu, etc.
Key Alt used to select a command from the active application menu without using the mouse. By pressing the Alt key, the user accesses the first menu item of the active application. Further selection of the command is carried out using the movement keys ↓ ← → and pressing the key Enter. Key Alt widely used in combination with other keys. Here are some of them:
Key Ctrl has no independent meaning, but when pressed together with other alphabetic or control keys, it changes their action. Here are some examples of using such combinations:
Shift(register) - provides change the register of keys(top to bottom and vice versa). For example, pressing a key Shift Together with the alphabet key, it allows you to enter capital letters.
Insert(insert) - switches insertion modes (new characters are entered between those already typed, moving them apart) and replacement modes (old characters are mixed in with new ones).
Delete(delete) - deletes a character from a position to the right of the cursor (information entry point).
Back Space deletes the character in front of the cursor, i.e. to the left of the information entry position. Recall that the key Back Space located on the keyboard above the key Enter.
Tab - tab key, in text editors, it moves the cursor to the right several positions at once until the next tab stop; in dialog boxes, it serves to move between various control elements.
Caps Lock- fixes uppercase, providing entering capital letters instead of lowercase letters. Note that the key Caps Lock Works only with letter keys and does not affect special character input.
Scroll Lock- used only in spreadsheets to scroll information without changing the active cell.
Print Screen- provides copying information, currently displayed on the screen in Clipboard.
Long bottom key untitled - intended for entering spaces (to separate words).
The Windows logo key displays Main menu Windows. In addition, it is used to execute some commands, a list of which is given in the table below:
| Keyboard shortcut | Purpose |
|---|---|
| Windows + Break | Opening a dialog box Properties of the system |
| Windows + D or Windows + M | Minimize all windows |
| Windows + Shift + M | Restoring minimized windows |
| Windows + E | Opening the My Computer window |
| Windows + F | Search for a file or folder |
| Ctrl + Windows + F | Search for computers |
| Windows + F1 | Displaying Windows Help |
| Windows + L | Lock the computer when connected to a domain or switch users if the computer is not connected to a domain |
| Windows + R | Opening a dialog box Execute |
| Windows+U | Opening Utility Manager |
The key serves to call the context menu of the selected object, i.e. it replaces right-clicking on the selected object.
Navigation keys
Navigation keys have the following purpose.
The ↓ ← → keys are used to move the cursor accordingly up, down, left and right per position or line.
Home and End- provide movement of the cursor to the first and last position of the line, respectively.
Page Up and Page Down- provide movement through the text one screen page back and forth, respectively.
Small numeric keypad
Small numeric keypad can be used in two modes: for entering numbers and for cursor control. These modes are switched using the key Num Lock.
A regular keyboard can be divided into several areas.
The topmost area of the keyboard contains keys that are not used for entering 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.
Functions of the "Esc" key .
Its main function is to cancel the command 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 pressing this key again will take you back to your game.
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 reviewed.
The top row of the keyboard contains function keys (limited by a red rectangle in the picture).
Function keys FI – F12 designed to perform certain actions assigned to them. The actions depend on the programs currently running on the computer, but usually the F1 key used to call the help system of the currently running program. If any program is running, then help about this program appears.
"F2" Booting the computer while pressing this key or the “Del” key makes it possible to configure the Bios of your computer.
"F3" Calls up the search window.
"F5" Reloads the open browser page.
"F8" Booting the computer while pressing this button makes it possible to work in the safe mode of the 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 boots, it allows you to “pause” the computer – pause the boot process.
Functions of the “Pause/Break” key. When loading Windows, first you see information appearing on the monitor about your computer, the hard drive, the state of the RAM, and all its components. The information displayed on the monitor appears and disappears quite quickly and is extremely difficult to comprehend. To be able to deal with it, you just need to press the “PAUSE” button. And to complete the operating system loading process, you must press any button on the keyboard. Sometimes used by some programs.
"Print Screen/SysRq" key.
Pressing this key allows you to take a screenshot of your monitor. When you press this key, and it is located in the picture in a red frame, at the moment it is pressed, the image currently on the monitor is saved in the computer memory. Next, we take the saved image from the computer memory using a regular graphic editor, you can use the “Paint” graphic editor, which is already built into the Windows operating system. If you use the “Alt+PrintScreen” key set, you take a photo of only the active window, but the entire screen. In the picture, the “Alt” keys are in a blue frame.
Key
Shift key.
Pressing this key and a symbol key simultaneously allows you to temporarily switch to uppercase (capital) letter entry mode, or enter another symbol 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 the capital letter “I,” you need to press the Shift key and, without releasing it, press the I key.
Tab key. It is indicated by an icon in the form of two counter arrows and pressing it gives an indent from the beginning of the line - a paragraph. Allows tabulation - horizontal alignment of characters. A tab character is equal to eight regular characters. Tabulation is used when creating text documents. Designed to move the cursor:
- when editing texts, it is used to move to the next tab stop, i.e. moving the cursor several positions forward;
- in dialog boxes, moves to the next request field;
- 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 located CapsLock key.
Pressing this key fixes the writing of capital letters. When pressed again, capital letters are written again. This mode is indicated by a light indicator in the upper right corner of the keyboard. Pressing again cancels the mode. When CapsLock is enabled, pressing the key
NumLock key
turns on and off the numbers located on the right side of the keyboard. If the keyboard is turned on, you can use it to enter numbers and arithmetic operations. 
When enabled, this mode is also indicated by an indicator in the upper right corner of the keyboard, signaling that the additional keyboard is in operation. Now, in addition to entering numbers from the main keyboard field, you can also enter them from the additional one. True, those symbols that are printed on the keys of the additional keyboard at the same time as numbers will not work.
In most cases, the described keyboard fields are sufficient for work, but for those who like to work with a compact numeric and control keyboard “a la calculator,” there is another additional key field - the one on the right. This field is called an additional keyboard, in contrast to the main keyboard field.
When you press this block of keys with numbers, the numbers are printed, but with one condition - when the “NumLock” key is turned on. When the NumLock key is turned off, the numeric keys perform other functions. 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.
The same keys move the cursor to the end and beginning of the line. When you press the “3” and “9” keys, the “PageUp” and “PageDown” keys are duplicated on the main keyboard, respectively. These same keys move the cursor up and down one screen. When you press the “2”, “4”, “8”, “6” keys, the cursor is controlled, which means that the work of the arrow key is duplicated.
Spacebar – this key creates space between letters.
The Space key is the largest key, located below the block of alphanumeric keys, used to enter a blank character, regardless of the case switch.
Spacebar function.
When using a key, words or symbols are separated from each other. But this key has an additional mode. In replacement mode, which you can enable using the “Insert” key, pressing the “Space” key enables a function that is the same as pressing the “Delete” key (this key erases characters on the right).
Backspace key – when you press this key, the character located to the left of the cursor is deleted.
Functions of the BackSpace or Left Arrow key.
When you press this key, we delete the selected one character or the entire text on the left. When you use this key in the file manager, you move up one level. And when viewing photos, by pressing this key, we go back one photo.
By using the “Alt+BackSpacr” keys together, we undo the action performed before.
Key
When doing work on a computer you use the numeric keypad, which is located on the right, then it is much better to use the “Enter” key, which is located on the same block.
Delete key is intended to delete an object, such as a folder, file, etc.:
- in the text, the character to the right of the current cursor position is deleted (with the line shifted to the left);
- in the folder windows, selected file system objects are deleted to the Recycle Bin.
You can also delete an unnecessary file by pressing the keys together "Shift+Delete". The Shift keys are indicated by a green frame. Just keep in mind that the file in this case will not be deleted through the trash can, and in this case it cannot be restored.
The “Delete” key, indicated by a blue frame, located on the numeric keypad block, along with the “.” performs the same actions when the “NumLock” key is turned off.
It is possible to open the “Task Manager” by pressing the key combination “Ctrl+Alt+Del”. These Ctrl and Alt keys are indicated by beige frames.
Key
- in the text, you switch between the modes of inserting and replacing characters or inserting a fragment from the clipboard (depending on the settings of Microsoft Word). If insert mode is enabled, 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 print between them. In this mode, the text is inserted, as it were, and the entire end of the phrase is moved to the right.
But in the “replacement” mode, if you insert a word between two words, then the word on the right is replaced by the word that you inserted.;
- in programs like Total Commander, objects are selected.
If you press the Inset key, the text will be printed on top of what you typed, erasing the last one. If you press this key again, this action will be terminated.
The “Insert” key, located in a blue frame, which is located on the numeric keypad block, together with the number “0”, works only when the “NumLock” key is turned off.
We can copy the text after selecting it if we use the “Ctrl+Insert” key combination. And when we use the “Shift+Insert” keys together, it becomes possible to insert text.
PgUp, PgDn, End, Home keys designed for cursor control.
Home key
moves the cursor to the beginning of the line, and End key
to the end of the line"), as well as either to the beginning of the list or the end of the list. 
Keyboard shortcut
Keyboard shortcut
PgUp key moves the cursor to the beginning of the page, and PgDn key - to its end.
Functions of the “PageUp” and “PageDown” keys.
The use of these two keys is used when working with text editors, or when working with documents where the height of the information is much greater than the height of your screen and there is a need to scroll in height. These keys are indicated by a red rectangle.
And the “PageUp” and “PageDown” keys, which are indicated by a blue rectangle and are located on the numeric keypad block only when the “NumLock” key is turned off, together with the numbers “3” and “9” scroll the screen down or up. The state of the NumLock key is controlled by an indicator light (the indicator light is on when the key is on).
Key
Keys
Functions using the “Ctrl” and “Alt” keys.
When you use these keys, you extend the capabilities of other keys. By using these keys in different variations, you perform different actions.
Keys Ctrl+Alt+Del These keyboard shortcuts open the task manager.
Combination keys Ctrl+A selects all objects at once, such as folders, files, text, etc.
Combination keys Ctrl+X cuts the selected object to the clipboard, such as a test, files, folders, etc.

When pressing keys Win+PauseBreak The System Properties dialog box will open.
Key<Контекст> calls the context menu of the object on which the mouse pointer is currently located.
When using the key, we call up the menu in the same way as when clicking on the right mouse button. This menu corresponds to the program that is enabled for your work. If you are on the “Desktop”, then by pressing this key you open the menu corresponding to the active element of the Desktop.
Cursor keys (navigation)
.
Perform various actions related to cursor movement:
- in the text, move the cursor one position in the indicated direction;
- on the Desktop and in the folder window, transfer the selection to another object;
- in the menu, move the selection to the next command;
- in tables, move the cursor between cells.
These keys are also used in many games to control objects.
These keys are also used in many programs, for example, to move through the pages of a document or when viewing photos to move to the next image.
Hotkeys in the browser
To zoom in or out on a page, just hold down Ctrl key and spin the mouse wheel. Up - the scale will increase, down - accordingly, it will decrease. The same can be done by simply pressing + or – while pressing Ctrl. To restore the font size, use a keyboard shortcut Ctr + 0 .

Features of a laptop keyboard.
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 a magic key
Lettering or symbols that have the same color as
- with F2 – turns on and off the wireless adapter (Wi-Fi);
- with F3 – opens the mail program;
- with F5 – reduces the monitor brightness;
- with F6 – increases it;
- with F7 – turns the monitor on and off;
- with F10 – turns on and off the built-in speakers;
- with F11 – lowers the speaker volume;
- with F12 – increases it;
- The screen brightness is increased by pressing the key where there is a “big sun” (there may be a “sun” icon in combination with the “increase” icon);
- decreasing - on the contrary, the one with the “small sun” (or maybe there is a “sun” icon in combination with the “reduce” icon);
- keys with “loudspeaker” icons in combination with “more” or “less” icons - increase/decrease volume;
- crossed out mouse – disable/enable the TouchPad panel;
- crossed out loudspeaker – mute/unmute sound, etc.
The actions when combining function keys with the Fn key may vary for different types of keyboards, 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 that came with it next to it, spend some time mastering all these wonders and they will become familiar to you.
Naturally implies excellent keyboard skills. Many functions that significantly speed up the execution of any work.
F1 - Call Windows Help. When clicked from the window of a program, it opens help for that program.
F2 - Rename the selected object on the desktop or in Explorer.
F3 - Open a search window for a file or folder (on the desktop and in Explorer).
F4 - Open a drop-down list (for example, the address bar list in the My Computer window or in Explorer).
F5 - Refresh the active window (open web page, desktop, explorer).
F6 - Switch between screen elements in a window or on the desktop. In Explorer and Internet Explorer, move between the main part of the window and the address bar.
F7 - Spell check (in Word, Excel).
F8 - When loading the OS - select the boot mode. Enable advanced text highlighting in Word. Selecting a fragment from the initial to the final cursor position occurs without holding down the Shift key. A second press of the F8 key highlights the word closest to the cursor. The third is the sentence containing it. Fourth - paragraph. Fifth - document. The easiest way to remove the last selection is by pressing the key combination Shift+F8. You can disable the mode by pressing the Esc key.
F9 - In some programs, updating selected fields.
F10 - Call the window menu.
F11 - Switch to full screen mode and back (for example, in Internet Explorer).
F12 - Go to selecting file saving options (File - Save As).
Esc - cancel the last command entered, exit the window menu (remove focus) or close the open dialog.
Tab — Enter tab stops when typing. Move focus across elements. For example, moving between the desktop, Start button, Quick Launch, taskbar, and system tray. Navigate through elements (including links) of an open document. Alt+Tab - switch between windows.
Shift - upper case key (non-fixed switching). Used simultaneously with other keys to type capital letters as well as uppercase characters.
The Ctrl+Shift or Alt+Shift combinations are usually used to switch keyboard layouts.
Capslock - upper case (fixed switching). Used when typing text in CAPITAL letters. Pressing the key again cancels this mode.
Alt - used in conjunction with other keys, modifying their action.
For example, Alt+letter - call a menu command or open a menu column. The corresponding letters in the menu are usually underlined (either initially, or become underlined after pressing Alt). If the menu column is already open, you can then press the key with the letter that is underlined in this command to call a specific command. The same applies to the open context menu.
Ctrl - used in combination with other keys. For example, Ctrl+C - copy, Ctrl+V - paste, Ctrl+Alt+Del - open Windows task manager.
Win (“start”) - opens the Start menu.
AppsKey - calls the context menu for the selected object (equivalent to right-clicking the mouse).
Enter - Confirm selection. Same as double clicking on an object. Clicking on the currently active button in the dialog. Often - clicking on the “default” button in the dialog. When entering commands from the keyboard, complete the command entry and proceed to its execution. When typing, move to a new paragraph.
Backspace - View a folder one level up in the My Computer window or Windows Explorer window. In text editing mode, delete the character to the left of the input cursor).
Delete — Delete the selected object, selected text fragment or character to the right of the input cursor.
Up, Down, Right and Left Arrows - Allows you to navigate through menu options. Move the input cursor in the appropriate direction by one position. The action of these keys in many programs can be modified using service keys, primarily SHIFT and CTRL.
Home - moves the cursor to the beginning of the current line of the document or to the beginning of the list of files.
End - moves the cursor to the end of the current line of the document or to the end of the list of files.
PageUp/PageDown — moves the cursor one page up or down. The term "page" usually refers to the portion of a document that is visible on the screen. Used to “scroll” the content in the current window.
Insert - Switch between insert and replace modes when editing text. If the text cursor is located inside existing text, then in insert mode new characters are entered without replacing existing characters (the text is, as it were, moved apart). In replace mode, new characters replace the text that was previously present at the input position.
PrtScn (print screen) - Takes a screenshot and places it on the clipboard. Alt+PrtScn - copying a screenshot of the currently active window (application) to the clipboard.
ScrLk (Scroll Lock) - refers to service keys. Its short description is scroll blocking. Designed for a screen display mode in which pressing the cursor keys leads to a shift not of the cursor as such, but of the entire contents of the screen. Now this key is used for this purpose very rarely, but, for example, in Excel it works. This is very convenient when editing large tables.
Pause/Break - pauses the computer (in DOS it worked everywhere, in modern operating systems - only while the computer was booting).
Numlock - Changes the numeric keypad mode. When turned on, the numeric keypad switches to digit entry mode; when turned off, the additional keyboard can be used to control the cursor.
Additional numeric keypad.
These keys are a favorite among bank tellers with nimble fingers and anyone who has to type a lot of numbers. The numeric keypad resembles a calculator and is located on the right side of the keyboard. (However, you must press the Num Lock key for it to work. If you don't, you'll be stuck with the cursor keys.)
When Num Lock is turned off, the keys on the secondary numeric keypad will act as cursor keys. They show small arrows showing the direction the cursor is moving across the screen. (The number 5 key, which does not have an arrow, does nothing but combat low self-esteem.) In addition, the cursor is controlled by keys with the words “Home”, “End”, “PgUp” and “PgDn”.
Good day and good mood to everyone, my dear friends. Force majeure can happen at any time and we always need to be prepared with a plan "B". What will you do if your keyboard suddenly “flies”? If things are urgent, then you can. What to do if the mouse breaks?
In fact, there is a solution, and even more than one. So don't rush to panic if you have some urgent work. I'll show you how to use a keyboard instead of a mouse. Of course, this is not a way out of the situation, but as a temporary urgent solution to the problem, it is just right.
Arrow navigation
Some people don't know or even bother, but in fact, all the functions of a mouse can be performed using the keyboard. And for this you don’t even need to call any third-party programs, etc. Default keys can do all this.
In fact, these are all basic combinations. To be able to use a keyboard as a mouse perfectly, you need to know them even more and train for a long time to do it automatically, like seasoned computer scientists. But if this method is not for you and you don’t want to bother, then the second method is suitable for you.
Mouse imitation
In addition to regular hotkeys, you can use a full-fledged mouse with a pointer, but work with it using the keyboard.
To do this, press the key combination ALT+SHIFT+NUM LOCK. After this, you will hear a strange sound signal and a sign will appear in front of you. Click OK. And now mouse mode will be activated.
But the truth is, the pointer speed leaves much to be desired. The mouse substitute is very slow. But there is a way out.
Now, when you activate the keyboard mouse, to speed it up, hold down the key CTRL. Then your work will become more convenient and much faster.
In general, to work more conveniently, more productively and faster, I recommend that you watch wonderful video course, which will help you with this.
