01 / THE BIG PICTURE

Parts of a computer keyboard, with a labelled diagram

A keyboard is an input device for entering text and numbers, editing work and controlling software. A full-size desktop keyboard separates these tasks into familiar areas. Laptop and compact keyboards often combine keys or place extra actions behind Fn.

02 / WHAT EACH KEY DOES

Keyboard keys and their functions

A–Z

Alphabet & symbols

The 26 English letter keys form words. QWERTY describes the first six letters on the upper letter row. Punctuation keys add marks such as commas and full stops. Shift selects the upper printed symbol on many keys; the exact character depends on your input layout.

0–9

Numbers & numeric keypad

Use the number row above the letters for digits. A separate numeric keypad puts digits and arithmetic keys together for repeated number entry. Num Lock commonly switches keypad digits and navigation actions on Windows keyboards. Learn the keypad independently: its home position is 4, 5 and 6.

Ctrl

Control & modifier keys

Shift, Ctrl and Alt change the action of another key. Hold the modifier, tap the other key, then release. Windows keyboards usually provide Ctrl and Alt on both sides. AltGr, where present, accesses extra characters and is not simply a second shortcut key. On Mac, Command handles many familiar editing shortcuts; Option is also labelled Alt.

↵

Typing & editing keys

Space separates words. Enter starts a paragraph in a text editor or activates a focused control. Backspace normally removes the character before the cursor; forward Delete removes the one after it. A selected text range can be removed by either. Tab moves between controls, or inserts a tab in editors. Shift + Tab commonly moves focus backward.

↑

Navigation keys

Arrow keys move the cursor or selection. Home and End commonly move to the start and end of a line in Windows editors; Page Up and Page Down move through larger portions of a document. Context matters: a web page, spreadsheet and text editor may respond differently. Compact keyboards may require Fn combinations.

F1

Function & special keys

F1 through F12 send function-key commands whose meanings depend on the app. Esc often cancels a task or closes a menu. Fn selects hardware-layer actions such as brightness, volume or standard function keys. Fn Lock behaviour depends on the keyboard manufacturer.

Modifier examples: Shift plus A makes a capital letter, Windows Ctrl plus C copies, and Windows Alt plus Tab switches apps
A shortcut combines keys. A plus sign in shortcut notation means “press together”; do not type the plus sign itself.

Shift, Caps Lock and case

Hold Shift for a single capital letter when Caps Lock is off. Caps Lock changes letter case until switched off; it does not normally select the upper symbol on number keys. For example, Shift + 1 produces ! on a US keyboard. Other layouts can behave differently.

Tab, Escape and special controls

Use Tab to follow the focus outline through a form; Shift + Tab goes back. Escape often dismisses a menu or cancels an operation. Insert can switch typing modes in supporting editors. Print Screen behaviour depends on system settings. Scroll Lock and Pause are legacy keys with limited, application-specific uses.

For a key that seems unresponsive, try the Keyboard Tester. Browser tools cannot intercept every operating-system or hardware shortcut.

03 / THE TOP ROW

What do F1, F2, F3 … F12 do?

There is no universal action for each F key. These are examples in named applications, not promises for every keyboard. On a laptop, you may need Fn or an Fn Lock setting. Apple keyboards can use the top row for system controls; Fn/Globe can expose standard function keys.

KeyExample useWhere / reminder
F1Open helpMany Windows applications; app support varies.
F2Rename a selected itemWindows File Explorer.
F3Search for an itemWindows File Explorer.
F4Show the address-bar listWindows File Explorer. Alt + F4 is a different shortcut: close a window.
F5RefreshWindows windows and common browsers; unsaved form work may be affected.
F6Move focus between interface areasWindows and Chrome; it does not insert text.
F7Toggle caret browsingChrome on Windows/Linux; this enables a text cursor for page navigation.
F8Application-definedNo general typing action. Check the app or keyboard manual.
F9Application-definedSome apps assign document tasks; there is no system-wide meaning.
F10Activate the menu barSupported Windows windows. Shift + F10 commonly opens a context menu.
F11Toggle full screenChrome on Windows/Linux.
F12Open developer toolsChrome on Windows/Linux. Other apps assign different actions.

Interactive layout viewer

QWERTY, QWERTZ, AZERTY and Dvorak

These simplified letter maps compare layouts; they are not complete keyboards. Regional variants differ, especially punctuation and number-row symbols. Changing this viewer does not change your device input settings.

Layout, keyboard shape and size are different things

Character layout

QWERTY, QWERTZ, AZERTY and Dvorak describe character arrangements. Your operating system’s selected input layout determines what is typed, so printed keycaps can disagree with the output. The main English course here teaches QWERTY.

Physical arrangement

ANSI-style and ISO-style keyboards differ physically, including the Enter key shape and keys near the left Shift. Language variants add or move symbols. Our diagram is a US ANSI-style example, not a map of every keyboard.

Keyboard size

Full-size models include a separate numeric keypad. Tenkeyless models omit it. Compact models may share navigation and function actions through layers. Key count alone does not tell you which language layout is selected.

Read different types of typing keyboards for keyboard choices, or follow the finger placement guide to learn which finger reaches each key.

04 / PUT THE KEYS TO WORK

20 useful keyboard shortcuts for beginners

These are common desktop conventions. The focused app decides what happens; check its menus when a shortcut differs. “Cmd” means Command on Mac.

05 / A SIMPLE LEARNING SEQUENCE

A keyboard lesson for students and teachers

Five everyday uses

  1. Write messages, essays and reports.
  2. Enter numbers in forms and spreadsheets.
  3. Edit, select and move through text.
  4. Navigate software and activate commands.
  5. Control games and other interactive tools.

Practise in five short steps

  1. Find letters, the number row, Space and Enter.
  2. Locate the F and J bumps; rest on ASDF and JKL;.
  3. Type a short sentence, then practise capitals with Shift.
  4. In a blank document, compare Backspace with Delete and move with arrow keys.
  5. Use Tab to move through a form; finish with one familiar shortcut.

For younger learners, teach one group at a time and use the Kids Typing Course. Keyboarding skills include finger placement, accuracy, steady rhythm, useful shortcuts and finding keys without repeatedly looking down. Speed develops through practice rather than memorising every shortcut at once.

Teacher tip: Print this page or save it as a PDF from your browser. Ask learners to label a keyboard, explain two key groups, and demonstrate Shift, Tab and Backspace in a practice document. The diagrams can be opened separately for classroom display.

Keyboard questions, answered

What are the five main types of keyboard keys?

A common teaching model groups keys into typing/alphanumeric keys, control keys, function keys, navigation keys and the numeric keypad. These are learning categories; a key can serve more than one role. This guide separates editing actions to make them easier to learn.

How many alphabet and number keys are there?

An English alphabet has 26 letters. A typical English keyboard has a top row with ten digit keys, 0–9; a separate numeric keypad repeats those digits. Total key counts vary by size, country and manufacturer.

What is the difference between Ctrl, Alt and Shift?

They are modifier keys used with other keys. Shift commonly changes letter case or selects a symbol. Ctrl and Alt commonly form commands. The result depends on the operating system, layout and app.

Why does my keyboard type a different symbol from the keycap?

The selected input layout may not match the printed keyboard, or a modifier/lock may be active. Check the operating system language and input settings before assuming the key is broken.

Is Delete the same on Windows and Mac?

The main Delete key on many Mac keyboards deletes backward, like Windows Backspace. Fn + Delete provides forward deletion on many Mac keyboards. A separate forward-delete key may be available on extended models.

Can I use this guide as a keyboard presentation?

Yes. Display the labelled diagram, work through the key-group cards and use the classroom sequence. The Print / Save as PDF control opens the browser print dialog for a printable guide; it does not download a PowerPoint file.

PRACTICAL GUIDE

Try the keys after reading the guide

Use the online keyboard to click letters, Shift, symbols, Enter and Backspace in a practice editor. This is a way to explore key actions with a mouse or touch screen; it is not a physical-keyboard typing-speed test. For hardware checks, use the separate keyboard tester. For touch-typing technique, follow the finger-placement guide and then the lessons.
