• Alt key: Short for Alternate, this key is like a second control key.
• Arrow keys: There are four arrow keys to move the cursor (or insertion point) up (↑), down (↓), right
(→), or left (←). Arrow keys can be used in conjunction with the
• Shift or Alt keys: To move the cursor in more than one position at a time.
• Backspace key: Deletes the character just to the left of the cursor (or insertion point) and moves the
cursor to that position.
• Caps Lock key: It is a toggle key, which when activated, causes all alphabetic characters to be
uppercase.
• Ctrl key: The control key is used in conjunction with other keys to produce control characters. The
meaning of each control character depends on which program is running.
• Delete key: The Del key deletes the character at the current cursor position, or the selected object, but
does not move the cursor. For graphics-based applications, the delete key deletes the character to the
right of the insertion point.
• Enter key or Return key: It is used to enter commands or to move the cursor to the beginning of the
next line.
• Esc key: The Escape key is used to send special codes to devices and to exit (or escape) from
programs and tasks.
• Function keys: Special keys labelled F1 to F12. These keys have different meaning depending on
which program is running.
Numeric keypad: It is normally located on the right-hand side of computer keyboard. It contains
numbers 0 to 9, addition (+), subtraction (–), multiplication (*) and division (/) symbols, a decimal point
(.) and Num Lock and Enter keys.
Home keys: Alphabets ASDF are home keys for the left hand and; (semi-colon) LKJ for the right hand.
Guide keys: On a computer keyboard, keys ‘F’ and ‘J’ are called guide keys for left and right hand,
respectively.
Typing capital letters: To type capital letters, switch ON the Caps Lock by pressing the key before
typing.
Typing symbols: The Shift key is used to access the top symbols that are one of the keys with two
characters.](https://image.slidesharecdn.com/keyboadingskillsnotes-250210111638-c812e644/85/DATA-ENTRY-AND-KEYBOARDING-SKILLS-NOTES-2-320.jpg)
DATA ENTRY AND KEYBOARDING SKILLS NOTES.
- 1. Data Entry and Keyboarding Skills A. Multiple choice questions: 1. Which of the following is not a key for punctuation marks? (a) comma (,) (b) period (.) (c) semicolon (;) (d) equal sign (=) 2. Which of the following is not an arrow key? (a) top (^) (b) down (↓) (c) right (→) (d) left (←) 3. Which of the following operation is not performed by a mouse? (a) Left Click (b) Right Click (c) Middle Click (d) Double Click A keyboard generally has more than 100 keys. Each key of a keyboard corresponds to a single symbol. Some symbols require pressing and holding several keys simultaneously or in sequence. Types of keys • Alphanumeric keys: All of the alphabet (A-Z) and numbers (0-9) on the keyboard. • Punctuation keys: All of the keys associated with punctuation, such as the comma (,), period (.),

- 3. Typing sentences: To get space between typed words, press the space bar once and then type the next word. Creating new lines and spaces between paragraphs: The Enter or return key is used to create new lines and spaces between paragraphs. Guide for typing: The cursor keys serve as a guide for typing. They can be used to move the position of the cursor. Pointing devices Instead of typing, directly some items can be selected from computer screen, for example "print" or "close" button. This can be done using point and draw devices, such as mouse. Mouse Mouse is a pointing device used to point a particular place on the screen and select to perform one or more actions Mouse pointer The mouse pointer allows to point on the screen. The pointer changes as shown below. The common mouse actions are as follows: (a) Click or left click: It is used to select an item. Press down once on the left button with your index finger. (b) Double click: It is used to start a program or open a file or trigger an action. (c) Right click: It is used to display a set of commands and available options. (d) Drag and drop: It allows to select and move an item from one location to another. (e) Scroll: Many applications provide scrollbars on right side of screen if the page length is more than the monitor/screen length. (f) Blocking: Blocking is another way of selecting text. It is used to select text that needs to be edited or formatted. Typing ergonomics Typing ergonomics provides the logistic support for efficient and effective typewriting. Sitting posture
- 4. While operating the computer keyboard, sit straight, slightly bending your neck forward. Monitor placement Do not bend your neck while working on the monitor and keep the upper border of screen at eye level. The distance of screen from the user depends on the size of the screen. Keep an approximate distance of about 60–65 cms for 17 inches screen. Mouse and keyboard placement Keep the keyboard and mouse together at an approximate distance of 20 cms, which will help in
- 5. smooth and effortless operation of keyboard. Same height of keyboard, mouse and elbows helps the users to work comfortably. Chair and table placement Adjust computer chair and table to an optimal height. The chair of the computer user must be supportive to his/her lower back. Placement of matter to be typed Place the matter for typing to the left or right side of the keyboard preferably on a Copy Holder which has a sloping surface. Positioning of fingers on the keyboard Allocation of keys to fingers The keyboard learning process starts from the second row (Home Row) followed by the Third Row (Upper Row), First Row (Bottom Row) and the Fourth Row (Number Row). Successful keyboarding tips
- 6. Press the keys with feather touch and do not put undue pressure. • Rest your fingers on home row while typing. • Allow your fingers to fall naturally on the keys so that each rests on top of the next key along the same horizontal row. • While typing, release the key immediately as soon as you press it. Holding the key for longtime, will repeatedly type the same character. • Do not look at the keyboard while practicing. • Press the keys with equal intervals of time in rhythm. • Press the keys only with the fingers allotted for them. • While pressing a key, say slowly pronounce the character on the key. Using typing software Introduction to Rapid Typing Tutor Rapid Typing Tutor is a Free and Open Source Software (FOSS) designed to learn typing skills on the computer. Touch typing technique Stage one of the process begins with learning the Home Row of the keyboard (the row beginning with the Caps Lock key). Looking at the keyboard is strictly forbidden. This is followed by learning the lower and upper rows, the numbers row, uppercase letters and special symbols. Stage two involves memorizing frequently used syllables and typing words containing these syllables Stage three involves typing actual text to perfect the skills acquired. How to interpret your results The color indication is as follows: • Green letters denote right inputs. • Yellow letters stand for right inputs exceeding the acceptable timeframe. • Red letters denote wrong inputs within the acceptable timeframe. • Orange letters indicate wrong inputs that also exceed the acceptable timeframe (it's the worst result).
- 7. Typing accuracy Accuracy in the words, percent Accuracy = ( 100% - Words with errors * 100%) / Total number of Words. Overall rating calculation (a) Good typing speed An average professional typist types usually in speeds of 50 to 80 wpm, while some positions can require 80 to 95 and some advanced typists work at speeds above 120 wpm. The fastest typing speed on an alphanumeric keyboard, 216 words in one minute, was achieved by Stella Pajunas in 1946. As of 2005, writer Barbara Blackburn was the fastest alphanumerical English language typist in the world, according to The Guinness Book of World Records.
