26 ;;; Commentary:
28 ;; The ideas for this package were derived from the C code in
29 ;; src/keymap.c and elsewhere. The functions in this file should
30 ;; always be byte-compiled for speed. Someone should rewrite this in
31 ;; C (as part of src/keymap.c) for speed.
33 ;; The idea for super-apropos is based on the original implementation
34 ;; by Lynn Slater <lrs@esl.com>.
36 ;; History:
37 ;; Fixed bug, current-local-map can return nil.
38 ;; Change, doesn't calculate key-bindings unless needed.
39 ;; Added super-apropos capability, changed print functions.
40 ;;; Made fast-apropos and super-apropos share code.
41 ;;; Sped up fast-apropos again.
42 ;; Added apropos-do-all option.
43 ;;; Added fast-command-apropos.
44 ;; Changed doc strings to comments for helping functions.
45 ;;; Made doc file buffer read-only, buried it.
46 ;; Only call substitute-command-keys if do-all set.
48 ;; Optionally use configurable faces to make the output more legible.
49 ;; Differentiate between command, function and macro.
50 ;; Apropos-command (ex command-apropos) does cmd and optionally user var.
51 ;; Apropos shows all 3 aspects of symbols (fn, var and plist)
52 ;; Apropos-documentation (ex super-apropos) now finds all it should.
53 ;; New apropos-value snoops through all values and optionally plists.
54 ;; Reading DOC file doesn't load nroff.
55 ;; Added hypertext following of documentation, mouse-2 on variable gives value
56 ;; from buffer in active window.
