The function find-emacs-tag, which you mentioned, is not in versions 18.50 or 18.52, so you might not want to use it in examples. Carl Witty cwitty@csli.Stanford.EDU I knew this, but forgot to mention it in my posting. find-emacs-tags is about the most useful of the various bits and pieces I have snarfed from the net. It is short, so I just appended it to this message. And it oughtter be in the distribution (added to tags.el)! Suggested filename: emacs-tags.el. Suggested binding (in your .emacs): (autoload 'find-emacs-tag "emacs-tags" "Package for finding tags in emacs sources themselves.") (global-set-key "." 'find-emacs-tag) Thanks, Carl! /jr jr@bbn.com or bbn!jr -------- ;;; Little function to enable finding tags in the emacs tags file itself. ;;; Credit Bob Webber, Wayne Mesard, Ashwin Ram ;;; Build the tags file with: ;;; % cd /usr/local/emacs/lisp ;;; % ../etc/etags *.el ../src/*.[ch] (defvar last-emacs-tag nil "Tag found by the last find-emacs-tag.") (autoload 'find-tag-tag "tags" "This hack is here because there's no provide in tags.el!") (defun find-emacs-tag (emacs-tagname &optional next other-window) "Invoke find-tag on EMACS-TAGNAME using the Emacs tag table. The state of the tags variables (tags-file-name and last-tag) are preserved so that a user can interleave calls to find-tag and find-emacs-tag.
