This looks interesting. I wanted to try it, however I couldn't find out
how to invoke it. I downloaded the *.el files mentioned, put them into
~/.elisp/load, and added the following lines to my ~/.emacs:

(add-to-list 'load-path (expand-file-name "~/.elisp/load"))
(load-library "icicles.el")

I start emacs, M-x shell RET, and get the shell prompt. I've read some
of the wiki pages, but it isn't clear for me how I can use Icicles. The
page about history doesn't mention shell at all, only minibuffer
completions. Any idea?

In bash, you can press C-r, and type, e.g., "dpkg". As you type each
character, bash shows the most recent command that matches the
expression you've typed up to that moment.

In emacs, I press M-r, it asks for a regexp, I type "dpkg". Nothing is
updated as I type, emacs waits for me to press RET to start searching. I
press RET, it finds the last dpkg command, which happens to be the 29th.
I see it isn't what I was looking for, and want to repeat the search. I
have to press M-r dpkg RET again (this is the "next run" I'd mentioned
in the first posting; "modifying" it is about the case you are not
satisfied with your initial regexp and want to enter a more specific one
instead of the one you typed at first). Or, I can press M-r M-r RET RET,
and emacs will search again. But only 32 commands back?!

So, what I'm looking for is more or less exactly bash's C-r
functionality. Can I perhaps just unbind emacs's C-r for shell buffers,
so that the character is passed to bash?


With kind regards,
Baurzhan.
