HP HP-28S - Finding a Command; Checking Command Use

Finding a Command
You can use the keys on the left-hand keyboard to move the catalog
to a specific character.
• Pressing a
letter key on the left-hand keyboard moves the catalog
to
the first command that starts with that letter. If there are no
commands starting with that letter, the catalog moves to the last
command starting with the previous letter.
• Pressing a
non-letter character key (such as .[]]) moves the cata-
log to
the first command that starts with that character. If there are
no commands starting with that character, the catalog moves to +,
the first command that starts with a non-letter character.
• Pressing
.1 MENUS 1 moves the catalog to -STR, the last entry in the
catalog.
Checking Command Usage
You can check the correct stack argument types for the command cur-
rently
displayed by the catalog. Pressing USE activates a second
level of the catalog, called the USAGE menu, that shows all combina-
tions of arguments for the command. If the command accepts more
than one combination of arguments, the following menu keys appear.
(If the command accepts only one combination of arguments, the la-
bels
NEXT and PREV don't appear.)
