When using JDraw it is possible to either draw a structure or copy/paste a structure from a chemistry package like ISIS/Base, Symyx/Draw or ChemOffice etc. by clicking the right mouse button on top of the structure input box. When using the JSME Molecular Editor one can draw a structure query as well but the copy/paste function will not be available.
