wasd is handled with the left hand index, ring, and middle fingers. Space is pressed with the left hand thumb. Lmb (left mouse button) is typically the right hand index finger. Lmb is not a keyboard keybind. You do not need three hands
i thought lmb was literally l m and b. w a s and d are represented as wasd so it's reasonable to assume that l m and b would be represented as lmb, especially after seeing it shown as lmb. also he could have just said left click. regardless, this does not eliminate the fact that it can run as good as a windows xp runs Skyrim, and it does not save your progress.
