learning how to type

backspace with pinky
, with middle finger
Ctrl preferably with the edge of your palm
Shift and Alt with knuckle of pinky
y with right index finger
x with middle finger
ad hoc combinations using {Shift,Alt,Ctrl} should be on the opposite side of the other key--in general, maximizing the distance between finger press positions.

I got 64 WPM (words per minute) which is pretty good.

I hate to break it to you, but that's about a standard deviation below average.
