Reaction arrows appear in many equations and you need to remember the codes necessary to produce them. FX ChemStruct uses EXACTLY the same codes and methods as FX Chem.
=> gives you a single arrow
< > gives you a double arrow
="above"> adds a message above the arrow
="above","below"> the comma allows information below the arrow as well
If you do not include the quotes, FX ChemStruct will interpret the text on the arrow as a chemical equation (NOT a chemical structure)
