This thread has nothing pertaining to your arm being angled or your wrists being stuck in an improper position while typing, but with which fingers you use to type.
When I first started to learn to type I didn't get any formal teaching of how to type, because everyone who I live with is garbage at typing. I sit by a computer for a long time playing video games, doing homework, typing for fun, etc. Naturally I found it difficult to play some games when I had to constantly look down to figure out which key to press. Also whenever I was messaging someone my neck didn't like the constant looking up and down. My logical decision was to force myself to suffer by missing about every single key by having my keyboard under my desk on a keyboard stand in order to learn where the keys are. Today I can type about 100-130wpm depending on how my typing style is at the time, but instead of using home row and 10 fingers I use the "whatever" row, and I only use about 6 fingers. I don't know how I got into the habit of using my right hand index finger for space bar, but that's how it is for me. I've tried home row, but it doesn't feel right and I don't like typing quite slow and my accuracy is horrendous.
Aside from the horrendous back story, is there anything you guys suggest on typing properly? I think eventually that I'll start developing issues in my right hand if I keep it up. Should I just suck it up and suffer some more by learning to type properly?
