## Silicon Graphics Buttons

Figure (fig-sgi-buttons): Silicon Graphics Button Assignments

The button box layout for the SGI Iris is given in Figure (fig-sgi-buttons) . Note that the ``right'' button shows you the right side of the model, as if you were looking in from the left. To achieve the customary draftsman views, this function goes on the left.

The upper left button is the help key. If this button is held down, and any other button (or knob) is activated, a descriptive string is displayed in the eight character LED display on the button box. The upper right button is used to reset all the knobs to zero. This is useful to halt a runaway rotation or zoom operation.
