You can map joystick command buttons to start selected Smart Review commands. By default, in relative mode, the first 3 buttons (1, 2, 3) are assigned the following commands:
Button 1 - Forward/Back, Left/Right
Button 2 - Rotate
Button 3 - Pan
You must assign the remainder of the buttons available for your particular joystick before you can start any of the other available commands from the joystick.
You can assign any or all of these buttons to a different command. You can arrange them in any order that you choose. Smart Review saves any change in the button mapping to the registry.
Entries in the button list that contain the letters POV are associated with the point of view switch (POV switch) on a joystick. Typically, a joystick provides eight available locations on the POV switch to which you can assign a command. POV 1 refers to the 12 o'clock position on the switch and the numbers are incremental for each additional 45 degrees moving around the switch clockwise.
