Try printing out an image of the Korean character keyboard, then taping it to your computer. It will help you learn the positions of the keys without needing to look down to remember. This is how I learned to type initially and in Korean :)

it just takes practice, don't you remember when you were in elementary school and you had those typing programs? :) well here's a very helpful tip: consonants on the left side, vowels on the right side took me some time but once you're used to it, its' a breeze. good luck :D

u mean u memorize the hangul, or u memorize the hangul in keyboard?
