'C' for carbon, then Press the left button on the mouse with the pointer in the correct position on the screen. Note that the interface will not allow you to place atoms too close together.   How to remove an atom Move the pointer of the mouse over the atom you wish to remove, then Press the adjust (right) button. Note that the interface will only allow a small amount of error in the positioning if the mouse pointer over an atom. And that all bonds connected to the atom to be removed will automatically also be removed for you.   How to bond two atoms together First select the bond order of the bond by pressing '1', '2', or '3', then Move the pointer of the mouse over the first atom you wish to join and click select, then Move the pointer of the mouse over the second atom you wish to join the first atom to and click select. Note that you can abort a bond addition by pressing 'A' after first selecting the first atom. You do not need to bond atoms as soon as you have drawn them and can leave adding bonds until the end. You can draw a bond over the top of another bond to replace it with one of a different bond order.   How to remove a bond First select bond removal by pressing '0', then Move the pointer of the mouse over the first atom the bond is joined to and click select, then Move the pointer of the mouse over the second atom that the bond is joined to and click select. Note that you can abort a bond addition or removal by pressing 'A' after first selecting the first atom.   How to submit the structure to the IUPAC parser Make sure that all atoms are joined and that there are no valency violations, then The molecule will be automatically named When you have finished noting the name you can modify the molecule.   This page is just a quick way for me to get my project online for the first time.
