See also Graphics Window Menu Bar for all the menu commands available.
See the separate topics Dialog Bar - Left, Dialog Bar - Right and Dialog Bar - Epitaxial for help on the controls on the left and right-hand sides of the Graphics window. This window shows the structure drawing. The drawing may be rotated with the mouse or with controls in the Dialog Bar - Left and rescaled with those in the Dialog Bar - Right. Other types of rotation, rescaling, etc. are available with commands in the menus, especially Input2 and Display.
To switch to other windows (see Types of Windows), click on the other window if it is visible, or use the Window menu or an option in the Display menu.
