Reaction Role Tool

The Reaction Role tool can be used to modify reaction roles that are automatically assigned when in reaction drawing mode. Point to a atom in the fragment whose role you want to change, using the arrow cursor and click. Select the role you want to use from the Role Specification Selection dialog.

Note: Reaction tools are disabled for normal drawing modes. Select the Rxn Tool from the toolbar or choose Show Reactions from the Display Menu.
