When using the realistic squares(world stamping tool) Arrow keys to move and all other keys to select tiles. Z to rotate. Left, up, right in order to switch to the solid color stamping tool(pattern stamping tool) When using the pattern stamping tool W, a, s, d keys to move. 0-9 to change colors. Along with q and e O to switch back to world stamping tool. R to switch to white color?(aka eraser)
Thanks to @super_squirtle123 for the world stamping tool.
