Introduction

In order to enhance operational skills in the use

of computers, knowledge of efficient and effective

keyboarding skills and typing ergonomics has become

inevitable today. With consistent, sincere efforts and

controlled environment, we can master keyboarding

skills and acquire high speed. Keying data into the

computer quickly and accurately, thus, becomes easy.

There are various methods of typewriting. In this

unit, we will study about various types of keys, typing

ergonomics and positioning of fingers on the keyboard

according to touch method of typewriting and use of

typing software for learning keyboarding skills.

Keyboarding Skills

Keyboard is the most common text-based input device.

Computer keyboards are similar to electronic typewriter

keyboards with additional keys. 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. It allows entering alphabets, digits and

symbols into the computer. Simultaneous key press

can produce actions or computer commands. The touch

method of typewriting is a method of typing without

using the sense of sight to find the keys. There is no

need to search the key while typing and one has to move

only the finger which is needed to strike a key.

A touch typist knows the location on the keyboard

through muscle memory. Touch typing typically involves

placing the eight fingers in a horizontal row along the

middle of the keyboard (the home row). Touch typing can

be done with two hands or by using a single hand also.

A touch typist starts by placing his or her fingers on

the “start position” in the middle row and knows which

finger to move and how much to move it for reaching any

required key. It is important to learn placing fingers into

the start position blindly as the hands are frequently

raised from the keyboard to operate the line feed lever

(in the past) or (more recently) the computer mouse.

Typing speed generally improves with practice. The

typing speed can be increased gradually and speeds of

60 WPM (words per minute) or higher can be achieved.

The rate of speed increase varies between individuals.

Many websites and software products (e.g., Rapid

Typing Tutor) are available to learn touch typing and

many of these are free. There are many such software

available which are free of cost and are customised to

learn typing efficiently and effectively.

Keyboards are also used for computer gaming, either

with regular keyboards or by using keyboards with

special gaming features.

Types of keys

Though there are several input devices viz. mouse,

touchscreen, character or voice recognition, etc., used

for giving input to the computer, yet the use of keyboard

is the most common method adopted for input of data

into a computer. 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.
