;; 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
+;; <cook@sightpath.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.
;; See the doc string of iswitchb for full keybindings and features.
;; (describe-function 'iswitchb)
+;; Case matching: The case of strings when matching can be ignored or
+;; used depending on the value of iswitchb-case (default is the same
+;; as case-fold-search, normally t). Imagine you have the following
+;; buffers:
+;;
+;; INBOX *info* *scratch*
+;;
+;; Then these will be the matching buffers, depending on how you type
+;; the two letters `in' and the value of iswitchb-case:
+;;
+;; iswitchb-case user input | matching buffers
+;; ----------------------------------------------
+;; nil in | *info*
+;; t in | INBOX, *info*
+;; t IN | INBOX
+;; t In | [No match]
