The mouse is considered to be the primary interface to the 3D window. The details of how to use the mouse to interact with the application are listed here. For those users with a single button mouse, holding down the Ctrl key while clicking or pressing the button will emulate using the Right mouse button on a three button mouse.
For those users not comfortable or familiar with the mouse interactions described below, the application can be made to emulate the mouse behavior of many other applications including: RasMol, Insight, Quanta, Sybyl, O, MOE, and Maestro. However, it is important to note that not all of the functionality described here is present in the emulated modes as the functionality may not have existed in the application being emulated.
