In the basic typing position, your index fingers are over the "f" and "j" keys. These keys typically have a raised line on them, so you can find the correct position without looking at the keyboard. The other fingers line up on the adjacent keys. As you learn typing, focus on accuracy instead of speed. Increased speed comes naturally as you progress and learn the position of all the keys.
