Don't use this long obsolete form. Use the keyword arguments, instead:
(define-minor-mode rich-minor-mode
"Brief description"
:lighter "")

I don't know what you mean with "then changed" nor where the above code
is intended to be placed (inside the `define-minor-mode`? In some
other function?).
Stefan
Have been trying to pass the parameters with names that mean something, rather
than
using
(define-minor-mode rich-minor-mode "Brief description" nil "" nil
so I would have
(define-minor-mode rich-minor-mode "Brief description" initval mdline-indic
other
Where can I find some information on using the keyword arguments? I only know
about the
long obsolete form.
