Keyboard layout: rows and groups of keys
Most English keyboards use the QWERTY layout (there are others, like AZERTY in France and Dvorak). Hindi typists often use the InScript layout on the same keys.
Rows
- Number row: 1 to 0 and symbols.
- Top row: Q W E R T Y U I O P.
- Home row: A S D F G H J K L ;.
- Bottom row: Z X C V B N M , . /.
- The space bar is the long key at the bottom.
Groups of keys
- Alphanumeric keys: letters and numbers.
- Function keys: F1 to F12 (e.g. F1 often opens help).
- Modifier keys: Shift, Ctrl, Alt change what other keys do.
- Navigation keys: arrows, Home, End, Page Up, Page Down.
- Numeric keypad: a calculator-style block for fast number entry.
Touch typing: home row and finger zones
Touch typing is typing with all ten fingers without looking at the keyboard. Your eyes stay on the screen or the text you copy.
- Rest the left fingers on A S D F (little, ring, middle, index) and the right fingers on J K L ; (index, middle, ring, little).
- Feel the bumps on F and J; they guide your index fingers home.
- Each finger presses only the keys in its column zone. The index fingers also cover the middle columns (G, H, T, Y, B, N).
- After each key, the finger returns to the home row.
- Press the space bar with a thumb; use the Shift on the opposite hand for capitals.
Special keys and shortcuts
- Shift: hold it to type a capital letter or the upper symbol on a key.
- Caps Lock: turns capitals on until you press it again.
- Enter: starts a new line or confirms a command.
- Backspace: deletes the character to the left of the cursor; Delete removes the one to the right.
- Tab: moves the cursor forward to the next stop or field.
- Common shortcuts: Ctrl+C copy, Ctrl+V paste, Ctrl+X cut, Ctrl+Z undo, Ctrl+S save.
Speed, accuracy and healthy posture
Gross WPM = (characters typed ÷ 5) ÷ minutes. Spaces count as characters.
Accuracy (%) = correct characters ÷ total characters × 100. Net WPM subtracts errors: Net WPM = Gross WPM − (errors ÷ minutes).
A beginner types about 15–25 WPM; a good touch typist 40–60 WPM. Practise 15 minutes a day, slowly and correctly; speed comes later.
Posture (ergonomics)
- Sit straight, feet flat on the floor.
- Elbows at about 90°, wrists level and not resting on the edge.
- Top of the screen at eye level, about an arm's length away.
- Take a short break every 30 minutes; look far away to rest your eyes.
Key formulas and definitions
- Gross WPM = (total characters ÷ 5) ÷ time in minutes
- Net WPM = Gross WPM − (errors ÷ time in minutes)
- Accuracy (%) = correct characters ÷ total characters × 100
- Home row: A S D F (left) · J K L ; (right)
- Touch typing: typing with all ten fingers without looking at the keys
Worked examples
1. Riya types 1,200 characters in 5 minutes. Find her gross WPM.
Words = 1200 ÷ 5 = 240. WPM = 240 ÷ 5 min = 48 WPM.
2. In a 2-minute test Arjun types 400 characters with 8 errors. Find gross WPM, net WPM and accuracy.
Gross WPM = (400 ÷ 5) ÷ 2 = 40. Net WPM = 40 − 8 ÷ 2 = 36. Accuracy = (400 − 8) ÷ 400 × 100 = 98%.
3. Which finger should type each letter of the word "THE" and which Shift key gives a capital T?
T: left index (it is in the left index zone). H: right index. E: left middle. For capital T, hold the RIGHT Shift with the right little finger and press T with the left index, because Shift is used by the opposite hand.
Common mistakes
- Looking down at the keys. It slows you and stops you learning key positions; keep eyes on the screen.
- Using only two fingers. Each finger has a zone; using all ten is faster and less tiring.
- Holding Caps Lock for one capital letter. Use Shift; Caps Lock is for long capital text.
- Chasing speed before accuracy. Errors you must fix cost more time than typing slowly and correctly.
