HP 49g Graphing Calculator - Manual (Page 35)

Most menus can be displayed as a fimction key menu
and
as a choose list
menu. Where this is the case, the default is to display the menu as a
choose list. If you prefer all menus to be displayed as function key menus,
clear flag -117.
Multi-screen menus
There may be more fimction-key menu items than cair be displayed on the
one screen. In this case, press (NXT)—or 0 (FE/)—to display further pages
of the menu.
Wliere there are more items on a choose list menu than can be displayed
on the one screen, press ® or ® to display fiuther items. You can also
jump directly to a choose list menu item by entering the first character of
the item (or, in the case of numbered menus, the number of the item).
Using the command line
The conuuand line is the area of the display where you can enter and edit
objects. It is always at the bottom of the display, immediately above the
menu. (See figure 2.1 on page 2-3.)
You do not have to first select the command line before entering a new
object. As soon as you start entering text—numbers or characters—the
conuuand line becomes active. For example, to multiply 5 by 6, enter 5
and note that the digit appears on the bottom line of your display. This is
the command line. A flashing arrow to the right of the 5 indicates that you
are in data entry mode. You then enter the rest of the object (by pressing
® and 6 in the example).
When you have finished entering your object, press (ENTER). If you entered a
calculation, the result of your calculation is displayed on the screen, on
the line below the calculation. Your calculation is retained so that you can
see how you derived the answer. (See page 2-21 for an example.)
You cancel a command line entiy by pressing (CMCEp. You will be asked to
confinu your intention if your entiy exceeds the width of the screen.
