scrollPaint(int);
shiftPaintColumn(int);
I knew them offhand so I guess that was a leg up for me, but I still opened the game to confirm. You couldn't have just run trace(bool) and pressed the buttons to move around in the paint can yourself? Anyway, use 1 to go down or right, use -1 to go up or left, and you can use numbers like 5 to shift 5 at once.
