I've been changing my typing style ever since I was 16 and I really haven't fond one I've particularly liked(19 now). I've gone from two fingers, to five(asdf gjhk) to (asdf hjkl). Changing is a painful process as I have to retrain my entire brain to have different fingers touch different keys. This starts up a slow process, then eventually I get to the same speed that I used to with the other method and in some cases surpass the quickness. What this is suggesting is that your fingers should be on the home keys (asdf hkl;), noting the pointer is on h and not j. Is that the typical/best way of typing or just some preference some people have? Seeing as I can't seem to pass 80wpm with what ever method I try and follow(Haven't tried the suggesting method yet). Also what home keys do you have your fingers on, how long have you been doing it and what's your average WPM?
