Keyboard tricks#

  • With nothing selected, press a letter like N or O to set the element.
  • With one atom selected, type a symbol to rename it. Type Cl or Br for two letters.
  • Type groups like Me, Ph or OMe too.

Change an atom#

Right click an atom. You can set the element, isotope, charge, explicit H, lone pairs and radicals.

Tip

The A button places an "any atom". It is the same as * in SMILES.
