Menus, Menu Items, and Assigning Values to Menu Items Many of the calculator's functions are located within menus. A menu is a catalog which permits you to select an item from a list of options. To access a menu, press the key, or secondary-function, key combination for the menu in which you wish to work. To exit a menu, press O. For example, to access the Bond menu, press B. Once opened, you can scroll through the items in the menu by pressing < or > repeatedly. When you arrive at the last item in a menu, pressing < returns you to the first item. Similarly, pressing > once on the first menu item scrolls to the last item in the menu. Some menus have sub-menus. If an item represents a sub-menu, pressing I with that menu item displayed opens the sub-menu. Most menu items consist of two parts: a name and an associated number. For example, the Fixed item in the Break-even menu is displayed in Figure 3. Figure 3 The large (=) annunciator shows that the value assigned to Fixed is 120,000. If you perform a calculation with this item displayed by pressing 1+2= for example, Fixed is still selected as the current item, but the large (=) annunciator is now turned off, indicating the 3 is not the value assigned to Fixed.
