If there are two compounds positioned after reaction arrow Marvin considers them as reaction products and separates them with "plus" sign. For example, products of reaction are toluene and methane and user wants to make ethylbenzene by dragging whole molecule of methane towards CH3-group of benzene to connect them. The result of his attempt would be disappearance of both molecules. The same is true for starting compounds.
