Look down and locate the home row on your keyboard.  Look at 
the second row from the bottom.  Place your left little finger on
A, your next finger on S, your middle finger on D, and your left 
index finger on F.  Now skip two keys.  Place your right index 
finger on J, your middle finger on K, the next finger on L, and 
the little finger on semicolon.  Study the location of these 
keys.
