6. Home Keys Alphabets ASDF are home keys for the left hand and LKJ and semi colon(;) for the right hand. The fingers are trained to make the correct movement to the other keys and each finger returns 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.
