	dashed bond: by default the bond does not count in the calculation of free valences. This can be change by right-clicking on a existing dashed bond and enabling the attribute “bond count” in the bond attribute popover (see How to edit bonds). wavy bond delocalized bond by clicking on a existing delocalized bond you can change the orientation of the dashed bondline or hide it (e.g. to symbolzie delocalization by alternating double and single bonds). Delocalized bonds with only one bondline are highlighted with yellow color. dative (corrdination) bond: by default the bond does not count in the calculation of free valences. This can be change by right-clicking on a existing dative bond and enabling the attribute “bond count” in the bond attribute popover (see How to edit bonds).
chain bond tool	add an atom chain. By dragging the further away, the chain gets longer. The orientation of the chain can be changed by holding the shift-key.

Ring system tools

In the ring system tools you will find simple ring systems that you can directly place into your sketch.
