(with delimiters), or the name of an equation,
expression, or program.
Specifies the menu keys—each entry defines one
key. Each entry can be either a variable name

Example:
The equation I = ppva/^ calculates the intensity of a
sound wave. Suppose you always calculate the value of p
and store it in the corresponding variable prior to using
this equation, and so would like to suppress p from the
SOLVR menu. Furthermore, suppose you want the IP
command available in the SOLVR menu so that you can
store integer values in the variables in the SOLVR menu.
The following solver-list list includes two additional keys:
a blank key and a key that executes IP (integer part) and
suppresses p.

The list, wdren stored in EQ, creates this menu of variables and
functions:
