In the appearing dialog the reactant data are already filled in and can't be modified. If you (optionally) click the reaction sketch area for entering a reaction sketch, it conveniently opens with the reactant and the reaction arrow already pre-drawn for you. Finally specify the step and product data in their appropriate boxes, then click OK to add the step.
