Arrow Keys. This is my attempt at fixing the old scrolling method and trying to create Borderless Scrolling. It's mostly visual trickery and I'm not sure how well it works depending upon the speed of computer.
This is only a test. If you were to actually make scrolling with this method, you'd want to have the moving pieces as big as you can get them. There is a Scratch offset oddity of around 7 pixels where it shows the edge of a piece not on screen yet and so movement must be higher than that. Even though I hide the pieces until close, there is still a moment when the edge will show and it's especially noticeable if lower than 8 movement. @MabonBaladevaKain
