The functions available are:
ASN: Assigns an object to a key specified by XY.Z
STOKEYS: Stores user-defined key list
RCLKEYS: Returns current user-defined key list
DELKEYS: Un-assigns one or more keys in the current user-defined key list, the
arguments are either 0, to un-assign all user-defined keys, or XY.Z,
to un-assign key XY.Z.
Recall current user-defined key list
Use command RCLKEYS to see the current user-defined key list. Before any
user-defined key assignments, the result should be a list containing the letter S,
i.e., {S}.
Assign an object to a user-defined key
Suppose that you want to have access to the old-fashioned PLOT command first
introduced with the HP 48G series calculator, but currently not directly available
from the keyboard. The menu number for this menu is 81.01. You can see this
menu active by using
ALG mode: MENU(81.01)
RPN mode: 81.01 ` MENU `
If you want to have a quick way to activate this menu from the keyboard, you
could assign this menu to the GRAPH key (C) whose reference number is
13.0, i.e., first row, third column, main function. To assign an object to a key
use function ASN, as follows:
ALG mode: ASN(<<MENU(81.01)>>,13.0)
RPN mode: << 18.01 MENU >> ` 13.0 ` ASN
Another useful menu is the original SOLVE menu (described at the end of
Chapter 6 in this Guide), which can be activated by using ‚(hold) 7.
