-;; Has been tested on Emacs 19.34 and XEmacs 19.14. I think it needs
-;; at least Emacs 19.29 to run.
-
-;;; Commentary:
;; As you type in a substring, the list of buffers currently matching
;; the substring are displayed as you type. The list is ordered so
;; common to all of the matching buffers as you type.
;; This code is similar to a couple of other packages. Michael R Cook
-;; <mcook@cognex.com wrote a similar buffer switching package, but
+;; <mcook@cognex.com> wrote a similar buffer switching package, but
;; does exact matching rather than substring matching on buffer names.
;; I also modified a couple of functions from icomplete.el to provide
;; the completion feedback in the minibuffer.
;;If I have two buffers called "123456" and "123", with "123456" the
;;most recent, when I use iswitchb, I first of all get presented with
-;;the default buffer (xxx) to switch to:
+;;the list of all the buffers
;;
-;; iswitch {default xxx}
+;; iswitch {123456,123}
;;
;; If I then press 2:
;; iswitch 2[3]{123456,123}
;; Of course, where this function comes in really useful is when you
;; can specify the buffer using only a few keystrokes. In the above
;; example, the quickest way to get to the "123456" buffer would be
-;; just to type 4 and then RET (assuming there isnt any newer buffer
+;; just to type 4 and then RET (assuming there isn't any newer buffer
;; with 4 in its name).
;; To see a full list of all matching buffers in a separate buffer,
;; hit ? or press TAB when there are no further completions to the
-;; substring.
+;; substring. Repeated TAB presses will scroll you through this
+;; separate buffer.
+
+;; The buffer at the head of the list can be killed by pressing C-k.
+;; If the buffer needs saving, you will be queried before the buffer
+;; is killed.
+
+;; If you find that the file you are after is not in a buffer, you can
+;; press C-x C-f to immediately drop into find-file.
;;

+;; functionality of the program. These are accessible using the
+;; custom package.
;; To modify the keybindings, use the hook provided. For example:
;;(add-hook 'iswitchb-define-mode-map-hook
;; 'iswitchb-my-keys)
;;
;;(defun iswitchb-my-keys ()
-;; "Add my keybings for iswitchb."
+;; "Add my keybindings for iswitchb."
;; (define-key iswitchb-mode-map " " 'iswitchb-next-match)

-;; Seeing all the matching buffers.
+;; Seeing all the matching buffers
+;;
;; If you have many matching buffers, they may not all fit onto one
;; line of the minibuffer. In this case, you should use rsz-mini
;; (resize-minibuffer-mode). You can also limit iswitchb so that it
;; only shows a certain number of lines -- see the documentation for
;; `iswitchb-minibuffer-setup-hook'.

+;; Changing the list of buffers
;; By default, the list of current buffers is most recent first,
;; oldest last, with the exception that the buffers visible in the
;; this is too harsh, let me know. Colouring of the matching buffer
;; name was suggested by Carsten Dominik (dominik@strw.leidenuniv.nl)
-;;; Comparison with iswitch-buffer
-
-;; This package is a rewrite of iswitch-buffer, using the minibuffer
-;; rather than the echo area. The advantages of using the minibuffer
-;; are several:
-;; o minibuffer has more powerful editing facilities
-;; o doesnt interfere with other packages that use the echo area
-;; o *Messages* buffer doesnt get filled up with all of the messages that
-;; go to the modeline
-;; o cursor is in the minibuffer, which somehow looks right.
-;; o minibuffer can be resized dynamically to show all the possible matching
-;; buffers rather than just the first line's worth (using rsz-mini).
-;;
-;; Disadvantages:
-;; o cant change the prompt to indicate status of searching (eg whether
-;; regexp searching is currently on).
+;; Replacement for read-buffer
+;; iswitchb-read-buffer has been written to be a drop in replacement
+;; for the normal buffer selection routine `read-buffer'. To use
+;; iswitch for all buffer selections in Emacs, add:
+;; (setq read-buffer-function 'iswitchb-read-buffer)
+;; (This variable should be present in Emacs 20.3+)
+;; XEmacs users can get the same behaviour by doing:
+;; (defalias 'read-buffer 'iswitchb-read-buffer)
+;; since `read-buffer' is defined in lisp.
+
+;; Regexp matching
+
+;; There is limited provision for regexp matching within iswitchb,
+;; enabled through `iswitchb-regexp'. This allows you to type `c$'
+;; for example and see all buffer names ending in `c'. This facility
+;; is quite limited though in two respects. First, you can't
+;; currently type in expressions like `[0-9]' directly -- you have to
+;; type them in when iswitchb-regexp is nil and then toggle on the
+;; regexp functionality. Likewise, don't enter an expression
+;; containing `\' in regexp mode. If you try, iswitchb gets confused,
+;; so just hit C-g and try again. Secondly, no completion mechanism
+;; is currently offered when regexp searching.

-;;; THINGS TO DO / BUGS
-
-;; In Xemacs, the default buffer is not shown the first time you enter
-; the minibuffer, but if you type a char and then delete a char, the
-; default appears. The first time we enter the minibuffer in XEmacs,
-; the default msg is not displayed, presumably because the hook is not
-; being called. I have put in a temporary hack therefore at the
-; bottom of this file.
-;
-; There is also a problem with the backspace key in XEmacs, so I have
-; bound it to the normal backward-delete-char.
