As for the keydown thing, thats not a limitation of Graal, thats a limitation of your keyboard.

My keyboard allows me to press left, right, and down at the same time. (So with your script, it = 3)
But I cannot do up/down/left.

However, if I use the num keys, I can do all four directional buttons at once. (The script outputs 4)

So, yeah.
