The molecules can be rotated by holding down the left mouse button while moving the mouse. The right mouse button can be used to move the view.
Zooming can be done with the scroll-wheel or by holding down both left and right buttons while moving the mouse up and down.
All molecules in the Molecule Project are listed in categories in the Project Tree. The individual molecules or whole categories can be hidden from the view by un-cheking the boxes next to them.
It is possible to bring a particular molecule or a category of molecules into focus by selecting the molecule or category of interest in the Project Tree view and double-click on the molecule or category of interest. Another option is to use the zoom-to-fit button () at the bottom of the Project Tree view.
