I always scroll by moving my cursor to the edge of the screen. However, I was watching a video (http://www.youtube.com/watch?v=wcFyqwNxx08) and this guy says he uses the arrow keys to scroll because it helps him microing the probe. However, I like to keep my left hand to the left side of the keyboard as much as possible since I find it easier to orientate. Anyway, I was wondering how you guys mostly scroll while playing. What do you find the best way to scroll while microing? Is it all just personal preference, or do all higher level players use the same way to scroll? Any advice on this matter is appreciated!
