If you want to use it, please give credit :P
I am not sure if I am the first one to discover this, but when I scrolled while messing with one of my projects, the key pressed Hat blocks ran the script below, which got me the idea for this detector. Also, the key sensing Boolean does not detect scroll, but only does detect the key, so with Hat Block:<When[UpArrowKey]Pressed> If <Not:[UpArrowKey]Pressed> Say:[Scroll Up] If this is a bug in Scratch 2, hopefully it will not get fixed :)
