Move is undocumented?

Just noticed that I couldnt find anything for Move in the manual. Not a sample but just a snippet that comes from @BackOrder's example #314

 motion do |left, top|
      @top_rect.move(left - (@controller.width / 2), top - (@controller.height / 2)) unless @controller.nil?
   end

I was wondering how is he moving those squares along the mouse.
