TYPING A TEXT, SENTENCE OR A PARAGRAPH
To type text, a sentence or a paragraph, perform the following:
• In the text editing mode, place your cursor at the required place.

letters.

it down in a pressed position to delete in a continuous process.
• Using Backspace key: Place the cursor to the right of the text to be deleted. Press Backspace key to remove the
letter. Keep holding it down in a pressed position to delete in a continuous process.

TYPING ERGONOMICS
Typing ergonomics is the science of providing the correct setup of a computer and a correct posture to reduce the
strain of muscles and joints due to repetitive typing posture for hours.
Correct sitting posture while working on the computer is very important to avoid long-term health issues. Following
are some tips for a proper sitting posture:
• The neck and the back should be relaxed and straight.
• Your feet should be flat on the ground. In case your feet do not touch the ground then put a proper footrest.
• Bend your knees at a 90-degree angle, and keep your knees at the same level or slightly lower than the hips.
• Leave a 2-3 inch small gap between the bottom of your thighs and the edge of the seat. This helps reduce pressure
build up on the underside of your thighs.
• Your keyboard should be placed in a slightly slanting position so that your fingers are typing downwards and your
wrists are more relaxed.
• The monitor should be placed at arm’s length distance, or 20 to 30 inches away.
• Eyes should be at a level with the top line of the screen.
• Elbows should be bent between 90-110 degree angles to reduce the strain on the hand and arms joints.
• Avoid leaning to any one side as the posture is affected. Keep the hips even to distribute weight of your body.
• Do not sit with your legs crossed as this will restrict the blood flow in your thighs.
• Take a break after every 30 minutes to avoid sitting for prolonged periods.
