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.

Indeed that's better advice, but I'm using a shitty compact tenkeyless mechanical keyboard where a FN key takes the normal position of the right Alt key.
