1. Discuss the various types of keys available on a computer
keyboard.
Ans1:
A computer keyboard contains the following 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 (.), semicolon (;), brackets ([]), and parenthesis ({ }) and so on. Also, all of the mathematical operators such as the plus sign (+), minus sign (-), and equal sign (=).
• 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.
2. Differentiate between Home Keys and Guide Keys.
Ans:
Home keys
Alphabets ASDF are home keys for the left hand and; (semi-colon) LKJ for the right hand. The fingers are trained to make the correct movement to other keys and each finger returns immediately to its respective home key after it has depressed the corresponding key in any other row
Guide keys
On a computer keyboard, keys ‘F’ and ‘J’ are called guide keys for left and right hand, respectively. Both contain a small raised tangible mark with the help of which the touch typist can place the fingers correctly on the home keys.
3. What do you understand by Guide Keys? Name the Guide
keys of a
(a) computer keyboard
(b) typewriter
Guide keys
On a computer keyboard, keys ‘F’ and ‘J’ are called guide keys for left and right hand, respectively. Both contain a small raised tangible mark with the help of which the touch typist can place the fingers correctly on the home keys.
Guide for typing
The cursor keys serve as a guide for typing. They can be used to move the position of the cursor.
4. Explain the role of typing ergonomics.
Typing ergonomics provides the logistic support for efficient and effective typewriting. They are important to attain and maintain accuracy and speed.
Some of these factors included
Sitting posture
While operating the computer keyboard, sit straight, slightly bending your neck forward.
Position of hands
Put your forearms at level with the keyboard and palms down
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 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. Keyboard and vibrating devices, such as printers, should be on separate tables. The computer table should also have sufficient space for your legs. With the correct ergonomics, typewriting becomes a natural phenomenon without causing unnecessary fatigue.
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
