It is important to understand that menu selections are set in a loop (Fig. 20

This means that

pressing the Scroll Down key (7, Fig. 2) cycles down through all the available options within a

given category, then returns to the first option. The Scroll Up key (

6, Fig. 2) cycles up through the

options in the opposite order. Note that this capability is a quick way to get to an option that is

near the bottom of the list. The following example demonstrates this capability.

Example:

To navigate to the “Select Item: Setup” menu option when the “Select Item: Object” menu is

displayed:

1. Press the Scroll Down key four times or the Scroll Up key once.

Autostar displays two lines of information. The top line shows the current menu level. The sec-

ond line displays an option which may be selected within that menu level. Some options are

choices that select the next menu level down. The Scroll keys move up and down within the list

of available options, showing one option at a time.

When the desired option is displayed on the second line, press the ENTER key to choose that

option and mo
