From 4414069939e7fa8c7b53ad1eee24d350f4b1fe0a Mon Sep 17 00:00:00 2001 From: Bill Wohler Date: Fri, 13 Jan 2006 06:40:14 +0000 Subject: [PATCH] * mh-search.el: New file containing contents of mh-index.el and mh-pick.el. C-c C-c launches your mh-index-program; C-c C-p runs pick. Pick no longer sets the "search" sequence. Instead, it brings up a folder view that we're accustomed to. (closes SF #829207). (mh-index-search): Rename to mh-search. (mh-pick-menu): Rename menu from Pick to Search. Rename Execute the Search to Perform Search and call mh-do-search. Add Search with Pick menu item. (mh-do-search): Delete. (mh-search-mode): Rename from mh-pick-mode. (MH-Search): Rename mode from MH-Pick. (mh-search-mode-map): Rename from mh-pick-mode-map. (mh-search-mode-help-messages): Rename from mh-pick-mode-help-messages. (mh-index-choose): Don't reuse the last value of mh-indexer; when mh-pick-do-search sets it to 'pick, we don't necessarily want to stay with that choice! * mh-index.el: mh-pick.el: Merge into mh-search.el and delete. * mh-customize.el (mh-index-program): Change mh-index-search to mh-search in docstring. (mh-tool-bar-search-function): Change default from mh-search-folder to mh-search. Remove mh-search-folder as choice and rename mh-index-search choice to mh-search. Fix docstring. (mh-pick-mode-hook): Rename to mh-search-mode-hook and change mh-search-folder to mh-search in docstring. * mh-e.el (mh-folder-folder-menu): Delete Search a Folder. Change Indexed Search to Search. Use mh-search instead of mh-index-search. (mh-folder-map): Delete i (mh-index-search) keybinding. Change s from mh-show-search-folder to mh-search. * mh-seq.el (mh-put-msg-in-seq): Fix docstring now that mh-search-folder no longer creates the search sequence. * mh-utils.el (mh-show-search-folder): Delete. (mh-show-folder-map): Delete i (mh-index-search) keybinding. Change s from mh-show-search-folder to mh-search. (mh-show-folder-menu): Delete Search a Folder. Change Indexed Search to Search.
