I touch type usually (I'll check the keys if my hands drift and I type every character shifted or something), but using ergonomic techniques has never been my style. My hands float around above the keys, so that I never have to stretch, unless to press certain uncommon keys. Instead of assigning certain keys to hands, I choose with which hand it would be more convenient to type it. For example, I'll press "m" with my left hand if my right hand is typing an "O". This is mainly because I like to alternate using fingers when I can, and I always stumble during one-hand words. I will use all of my fingers, but because I have my wrists raised, I tend to use the index finger of my right hand and the middle of the left, and using my right thumb to absolutely SLAM on the spacebar between words when I'm typing quickly, just because it lets me know I've finished the word and I can move on. When I get my mechanical keyboard, which will hopefully help me learn some technique with its thick keys and lurvely brown switch, I should get better at mechanics.
