Re: It is prompting me for a filename. I would like to fill in the current filename.

[Jeff Dwork]

I wrote this many years ago.  It never made it into the elisp
archives, but it is in Google's gnu.emacs.sources archive as
"mini-ibfn.el".  I just tested it on emacs 21.1 and it still works.

It's short, so I'll include it here:

;;; mini-ibfn.el --- insert buffer-file-name (with or without directory) into 
minibuffer.

;;; Commentary:

;; Purpose:
;;
;; To provide a quick way to insert the current buffer-file-name into
;; the minibuffer.  If the current buffer is a dired buffer, inserts
;; the filename point is on.
;;
;; Very useful for finding related files, doing copies or renames, etc.
;;

;; Installation:
;; 
;; Put this file somewhere where Emacs can find it (i.e., in one of the paths
;; in your `load-path'), `byte-compile-file' it, and put something like this
;; in your ~/.emacs:
;;
;;   (load "mini-ibfn" nil t)
;;   (define-key minibuffer-local-map "\C-c\C-f" 
'minibuffer-ins-buffer-file-name)
;;   (define-key minibuffer-local-ns-map "\C-c\C-f" 
'minibuffer-ins-buffer-file-name)
;;   (define-key minibuffer-local-completion-map "\C-c\C-f" 
'minibuffer-ins-buffer-file-name)
;;   (define-key minibuffer-local-must-match-map "\C-c\C-f" 
'minibuffer-ins-buffer-file-name)
;;
;; minibuffer-ins-buffer-file-name has been tested on FSF Emacs 18.59 and 19.28.
;;

;; Feedback:
;;
;; Please send me bug reports, bug fixes, and extensions, so that I can
;; merge them into the master source.

              (insert b-f-name)
