Mouse's buttons use
As well as selecting the functions to be used, the left mouse button is used to select entities, either individually or picking several within a given area (see Entity selection), and to enter points in the plane z=0 (see Point definition).
The middle mouse button is equivalent to escape (see Escape).
The right mouse button opens an on-screen menu with some visualization options. To select one of them, use the left or right mouse button; to quit, left-click anywhere outside the menu.
The first option in this menu is called Contextual. You can select from different options relevant to the function currently being used.
Zoom: Lets user choose different options like: zoom in, out frame, dynamic...
Rotate: Lets user choose different rotation modes, like trackball, screen axes, object axes...
Pan: Lets user choose different traslation modes, by two points or dynamic.
Redraw: Redraws the model.
Render: Lets user change the render: Normal, Flat, or Smooth; change the light direction or create a reflection.

Layer: Lets user create a new Layer, turn on/off the current layer...
Full screen: Switch between fullscreen mode and normal mode.

When the mouse is moved to different windows, depending on the situations, different cursor shapes and colors will appear on the screen.
In some windows a help option will appear when you click the middle or right mouse buttons over an icon.
