Appendix A: Key Functions
The function of each of the five RayData keys depends on:
• The circumstances in which it is pressed: that is, the information that
is currently displayed on the screen
• The way in which it is pressed: that is, whether you press the key
momentarily or press and hold it
• Whether it is pressed in combination with other keys
The following table reviews the functions of all the RayData key
presses, including combination key presses, depending on how they
are pressed and in what circumstances.
