HP 49g Graphing Calculator - Manual (Page 34)

Menu
A menu is displayed across the bottom of most screens. Each item on the
menu is one of the following:
® a command
® the name of another menu
® a variable
* a subdirectory.
The menu changes according to tire key, command, or sub-menu you
select. For example, if you press @D, the menu displays the variables and
directories you can access from your current path. (Variables are the
named objects that you have created aird saved, and subdirectories are
areas of memory you have set aside and named, usually to help you better
manage the storage of saved objects. Variables and directories are
explained in detail in chapter 7, “Storing objects”.)
Wlren you press certain other keys, the menu changes to show commands
or other menus. Wlien chosen, a command enables you to perform some
operation on data, such as a mathematical operation, a storage operation,
a imit conversion operation, and so on).
Many of the more commonly used commands have a key of their own. For
example, you can store an object by pressing (STO^. or find the sine of an
angle by pressing (siD. Other commands need to be selected from menus.
Selecting a menu item
A menu item that is displayed at the bottom
of tire screen can be selected by pressing the
fimction key—that is, one of the keys
labelled (Tj) to (£6)—directly below the item.
In the example on the right, to select
EDIT
from the menu, you would press (H), since
(£1)
is directly below
edit
.
While function key menus are widely
available, most HP 49G commands are more
easily accessible from choose list menus.
This type of menu—in the form of a scrolling
list—displays
similar groups of commands
(such as calculus commands, trigonometry
commands, and so on). To see an example of such a menu, press
