hmm...I use 9 fingers to type, and the only finger that I don't
use is my right thumb, as it's shares the same purpose as your left
thumb, which is to hit the spacebar.
both my baby fingers arn't use that much either, basically the left
one only hits the left "Shift" button, and my right baby finger
hit's the right 'Shift' and 'Enter' button.
other than that ther rest of my fingers are used in typing. I never
learnt the proper way of typing, but I'm able to type as fast and
as accurately as my sister, who has learnt the proper way.
