    There is also
    URL: http://www.emacswiki.org/cgi-bin/wiki/icicles-mode.el
    seems still more elaborated.

(Thanks for the plug.) There are many ways to switch among buffers,
including different ways to cycle among them or match their names. Different
users like different approaches, whether due to the different ways they use
Emacs or just to personal preference.

Here is "Switch-Buffers Central":

The OP said he couldn't find anything on this by searching. Always remember
that you can search not only the Emacs manual but also the Emacs Wiki:
http://www.emacswiki.org/cgi-bin/wiki/SiteMap. The Wiki includes libraries
that are not included within Emacs itself, and it also often includes
discussion and advice about different approaches, including vanilla Emacs
features.
