34 ;;====================================================================
|
|
|
35 ;; Instructions
|
|
|
36
|
|
|
37 ;; Searching with isearch-mode.el should work just like isearch.el,
|
|
|
38 ;; except it is done in a temporary minor mode that terminates when
|
|
|
39 ;; you finish searching.
|
|
|
40
|
|
|
41 ;; Semi-modal searching is supported, using a recursive edit. If
|
|
|
42 ;; isearching is started non-interactively by calling one of the
|
|
|
43 ;; isearch commands (e.g. (isearch-forward), but not like gnus does
|
|
|
44 ;; it: (call-interactively 'isearch-forward)), isearch-mode does not
|
|
|
45 ;; return until the search is completed. You should still be able
|
|
|
46 ;; switch buffers, so be careful not to get things confused.
|
|
|
47
|
|
|
48 ;; The key bindings active within isearch-mode are defined below in
|
|
|
49 ;; `isearch-mode-map' which is given bindings close to the default
|
|
|
50 ;; characters of isearch.el for version 19. With `isearch-mode',
|
|
|
51 ;; however, you can bind multi-character keys and it should be easier
|
|
|
52 ;; to add new commands. One bug though: keys with meta-prefix cannot
|
|
|
53 ;; be longer than two chars. Also see minibuffer-local-isearch-map
|
|
|
54 ;; for bindings active during `isearch-edit-string'.
|
|
|
55
|
|
|
56 ;; The search ring and completion commands automatically put you in
|
|
|
57 ;; the minibuffer to edit the string. This gives you a chance to
|
|
|
58 ;; modify the search string before executing the search. There are
|
|
|
59 ;; three commands to terminate the editing: C-s and C-r exit the
|
|
|
60 ;; minibuffer and search forward and reverse respectively, while C-m
|
|
|
61 ;; exits and does a nonincremental search.
|
|
|
62
|
|
|
63 ;; Exiting immediately from isearch uses isearch-edit-string instead
|
|
|
64 ;; of nonincremental-search, if search-nonincremental-instead is non-nil.
|
|
|
65 ;; The name of this option should probably be changed if we decide to
|
|
|
66 ;; keep the behavior. One difference is that isearch-edit-string does
|
|
|
67 ;; not support word search yet; perhaps isearch-mode should support it
|
|
|
68 ;; even for incremental searches, but how?
