Which tips helped you learn touch-typing?
I've been coding for many years (>10), and I can average only about 40wpm. My error rate seems pretty rubbish, and when I am coding I find it much harder to type fast because of all trickier characters.
About 4 years ago, I tried to force myself to touch type rather than the 4-fingered typing I'd been doing for many years before. I'd say that I'm probably slightly faster than I used to be, but would love to get more nimble and faster.
Is there any advice to get better at typing, other that what I have been doing, which is to try to position my fingers correctly, and use practice sites such as www.keybr.com ?
