immediately to its respective home key after it has pressed the corresponding key in any other
row.

7. Guide keys
 The 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.

8. Points to be kept in mind while typing
Press the keys gently, don't put much pressure.
Rest your fingers on Home row while typing.
While typing, release the keys immediately as soon as you press it
otherwise it will repeatedly type the same character.
Try typing without looking at the keyboard. At initial stage , you may face
problem but slowly and gradually you will learn with practice.
Press the keys only with the fingers allotted for them.
Maintain patience if committed mistake at initial stage.
Maintain a balance between speed and accuracy, as both are equally
important.
To be a master at typing, daily practice it. You can start with small words ,
then move onto sentences and further to paragraphs. But without looking
the letters.

Typing Ergonomics

15. Position of hands : keep your wrists straight. Don't touch the elbows to the
body. Bend at about 90 degree angle.

size of the screen.
There should be at least 50-80 cm distance between your eyes and the screen.
Mouse and keyboard placement: Keep the keyboard and mouse at an
approximate distance of 20 ems, which will help in smooth operation of
keyboard.
Chair and table placement : The chair of the user must be supportive to his
lower back.
