That's not a library command, that's for sure, but it's easy to write
it.  You can learn how to configure emacs to do this kind of things by
reading:


  An Introduction to Programming in Emacs Lisp
  http://www.gnu.org/software/emacs/emacs-lisp-intro/  or  M-: (info 
"(eintr)Top") RET
  (for non programmers)

  Emacs Lisp Manual
  http://www.gnu.org/software/emacs/manual/elisp.html  or  M-: (info 
"(elisp)Top") RET

  Emacs Manual
  http://www.gnu.org/software/emacs/manual/   or  M-: (info "(emacs)Top") RET


For example, you could write:

(defun capitalize-randomly (start end)
   (interactive "r")
   (goto-char start)
   (while (< (point) end)
     (let ((ch (char-after (point))))
       (delete-region (point) (1+ (point)))
       (insert (format "%c" (if (zerop (random 2))
                               (upcase  ch)
                               (downcase ch)))))))


So  with M-x capitalize-randomly RET you can get something like:
