;;; elisp-slime-nav.el --- Make M-. and M-, work in elisp like they do in slime

;; Author: Steve Purcell <steve@sanityinc.com>

;; Keywords: navigation slime elisp emacs-lisp

;; Version: 0.3

|
;;; Commentary
|
|
;;
|
|
;; This package provides Slime's convenient "M-." and "M-," navigation
|
|
;; in `emacs-lisp-mode'.
|
|
;;
|
|
;; Additionally, C-u M-. will prompt for the symbol to which to jump.
|
|
;;
|
|
;; Usage:
|
|
;;
|
|
;; (require 'elisp-slime-nav)
|
|
;; (add-hook 'emacs-lisp-mode-hook (lambda () (elisp-slime-nav-mode t)))
|
|
;;
|
|
;; Known issues:
|
|
;;
|
|
;; When navigating into Emacs' C source, "M-," will not be bound to
|
|
;; the same command, but "M-*" will typically do the trick.
