Data Entry and Keyboarding Skills Notes

Keyboarding Basics & Touch Typing

• Keyboard Overview: Primary text input device containing over 100 keys for alphanumeric characters, punctuation, and system commands.

• Touch Typing Method: Typing relying on muscle memory without visual assistance, moving only the required finger while returning to home positions.

• Key Categories:

  • Alphanumeric Keys: All letters ($A-Z$) and numbers ($0-9$).

  • Punctuation Keys: Symbols like commas (,), periods (.), semicolons (;), brackets ([]), parentheses ({}), and arithmetic operators ($+$, $-$, $=$).

  • Control & Toggle Keys: Alt, Ctrl, Caps Lock (toggles uppercase text), Esc (exits tasks or sends special codes), and Function Keys (F1 to F12).

  • Navigation & Deletion Keys: Arrow Keys (up, down, left, right), Backspace (deletes character to the left), Delete (deletes character at or to the right of cursor), and Enter / Return (executes commands or starts a new line).

• Numeric Keypad: Positioned on the right side for fast numeric entry; features dual modes (numbers or navigation/page keys) toggled via NumLock.

• Home & Guide Keys:

  • Home Keys: ASDF for the left hand and ;LKJ for the right hand.

  • Guide Keys: F and J keys feature tiny raised tactile marks to guide finger placement without looking.

Pointing Devices & Mouse Operations

• Pointing Devices: Tools to select items on screen without a keyboard, including joysticks, light pens, touchpads, trackballs, and touchscreens.

• Mouse Technology & Components: Consists of buttons, a handling area, and a motion tracking system using either a tracking ball or an optical light beam sensor.

• Mouse Operations:

  • Click / Left Click: Pressing the left mouse button once with the index finger to select an item.

  • Double Click: Starts programs, opens files, or triggers actions.

  • Right Click: Opens a menu of available options and commands.

  • Drag and Drop: Relocates objects by holding the left button down while moving the mouse.

  • Scroll: Moves the page view up or down using the scroll wheel.

  • Blocking: Highlighting text for editing or formatting by clicking, holding, dragging, and releasing the left mouse button.

Typing Ergonomics & Finger Positioning

• Ergonomic Guidelines:

  • Sitting Posture: Sit upright with the neck slightly bent forward, feet flat on the floor, and lower back supported by the chair backrest.

  • Hand Position: Forearms level with the keyboard, wrists straight, and elbows hanging freely bent at a 90-degree angle.

  • Monitor Placement: Position screen upper border at eye level; keep a distance of roughly 60–65 cm for a 17-inch screen.

  • Mouse & Keyboard Placement: Maintain a 20 cm gap between keyboard and mouse at identical heights.

  • Copy Holder: Place target typing text on a sloping copy holder to the left or right of the keyboard.

• Finger Allocation by Row:

  • Second Row (Home Row): Initial finger resting place (ASDF / ;LKJ); keys g and h are operated by the left and right index fingers.

  • Third Row (Upper Row): Reaches from Home Row to upper keys (QWERT / YUIOP).

• First Row (Bottom Row): Reaches to keys Z, X, C, V, B, N, M, comma, full stop, and / sign.

• Fourth Row (Number Row): Left hand types 1, 2, 3 with little, ring, and middle fingers, and 4, 5 with index finger. Right hand types 0, 9, 8 with little, ring, and middle fingers, and 7, 6 with index finger.

• Numeric Keypad Home Row: Center practice row containing 4, 5, 6, and +.

Rapid Typing Tutor & Performance Metrics

• Rapid Typing Tutor: Free and Open Source Software (FOSS) for learning touch typing across three distinct stages:

  • Stage One: Learning the Home Row without looking at the keyboard.

  • Stage Two: Memorizing frequent syllables and words.

  • Stage Three: Typing full text to perfect speed and accuracy.

• Feedback Indicators:

  • Green Letters: Correct input within acceptable time.

  • Yellow Letters: Correct input exceeding acceptable time.

  • Red Letters: Incorrect input within acceptable time.

  • Orange Letters: Incorrect input exceeding acceptable time (worst result).

• Error Window: Displays error percentage and delay percentage for lessons using Graph/Bar chart or Table view to identify difficult keys.

• Speed & Accuracy Metrics:

  • Words Per Minute (WPM): Counts words typed per time period; least accurate due to average word length assumptions.

  • Characters Per Minute (CPM): Measures total characters typed per time period.

  • Keystrokes Per Minute (KPM): Measures total individual keystrokes; most accurate speed metric.

  • Typing Accuracy: Percentage of correct entries relative to total entries typed.
