It is important to understand that menu selections are set in a loop (Fig.44
).
This means
that pressing the Scroll Down key cycles down through all the available options within a
given category, then returns to the first option. The Scroll Up key 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 five times or the Scroll Up key once.
The screen in
Fig. 44a displays two lines of information. The top line shows the cur-
rent menu, "Select Item." The second line displays an option within that menu,
"Object."
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. The
example in
Fig. 44a shows the Select Item menu with the Object option displayed on
the second line.
When the desired option (Object) is displayed on the second line, press the ENTER
k
e
y to choose that option and move down one menu level.In the example, press Enter
and the displa
y no
w reads "Object: Solar System." You have moved down to the
Object menu level. See
Fig. 44b. You can now use the up and down keys to scroll
through the other options available for the Objects menu: Constellations, Deep Sky,
etc.
Press the MODE key to leave a menu level;
e.g., the wrong menu option is chosen.
Impor
tant Note:
No matter ho
w man
y levels into Autostar II are traveled,
each press of the MODE key moves up a level, until the top level, "Select
Item," is reached. Once in the Select Item level, press MODE to return to
the topmost level, "Select Item: Object."
