Move the mouse to the left for the palette to appear. Don't add or remove lists, because they will cause bugs (it corrupts the list of sprites). [R] hold to reset the editor. [D] to duplicate the block below mouse [C] clean up [arrow keys] to scroll [space] create block by opcode (see blockdefs list, and blockInfo list)
