Simply so, where do I put my fingers on a keyboard?
The fingers on your left hand should be placed over the A, S, D, and F keys and the fingers on your right hand should be placed over the J, K, L, and ; keys. These keys are considered the home row keys. Your thumbs should either be in the air or very lightly touching the spacebar key.
Similarly, how many fingers should you type with? eight
Similarly, what finger do you type M with?
Each index or pointer finger is responsible for two rows of keys. The right hand pointer takes the “U” and “M” column, as well as the “Y,” “H” and “N” keys.
Should keyboard be flat or raised?
Flat and without wrist rest. The optimal way to type is to hold your wrists level with your fingers; tilt makes the keyboard even higher and therefore worse on your wrists. It's less tiring to your arms, but then your relatively fragile wrists will receive all the strain instead, rather than your arms/shoulder.
