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.

Operating user-defined keys

To operate this user-defined key, enter „Ì before pressing the C key.

Notice that after pressing „Ì the screen shows the specification 1USR
