CMPLX menu in keyboard
A second CMPLX menu is accessible by using the right-shift option associated
with the 1 key, i.e., ‚ß. With system flag 117 set to CHOOSE

The resulting menu include some of the functions already introduced in the
previous section, namely, ARG, ABS, CONJ, IM, NEG, RE, and SIGN. It also
includes function i which serves the same purpose as the keystroke
combination „¥, i.e., to enter the unit imaginary number i in an
expression.
The keyboard-base CMPLX menu is an alternative to the MTH-based CMPLX
menu containing the basic complex number functions. Try the examples
shown earlier using the keyboard-based CMPLX menu for practice.
