32 ;;; Commentary:
34 ;; The speedbar provides a frame in which files, and locations in
35 ;; files are displayed. These items can be clicked on with mouse-2 in
36 ;; to display that file location.
38 ;;; Customizing and Developing for speedbar
40 ;; Please see the speedbar manual for informaion.
42 ;;; Notes:
44 ;; Users of really old emacsen without the need timer functions
45 ;; will not have speedbar updating automatically. Use "g" to refresh
46 ;; the display after changing directories. Remember, do not interrupt
47 ;; the stealthy updates or your display may not be completely
48 ;; refreshed.
50 ;; AUC-TEX users: The imenu tags for AUC-TEX mode don't work very
51 ;; well. Use the imenu keywords from tex-mode.el for better results.
53 ;; This file requires the library package assoc (association lists)
54 ;; assoc should be available in all modern versions of Emacs.
55 ;; The custom package is optional (for easy configuration of speedbar)
56 ;; http://www.dina.kvl.dk/~abraham/custom/

1041 Files with a `#' or `!' character after them are source files that
