                (push sym internals))))
  (insert (format "%S\n" internals)))

I've not found any predicate to distinguish between built-in functions
and special forms.

Wow,That works wonderful.
Thank you,
Using your method, I found 974 entries:
             which includes built-in functions and special forms

C-h f TAB gives me 7129 entries.

Applying the educational approach,
 I like to find out what I can do with my progressive learning.

 To achieve that,
 I like to find lisp functions (example:defined with defun)  which
uses  the set of internals or functions that I learned so far. I can
further restrict it by specific set of files.

Thanks,
Artist.
