iswitchb-buffer is an interactive compiled Lisp function in `iswitchb'.
 (iswitchb-buffer)
 
 Switch to another buffer.
 
 The buffer name is selected interactively by typing a substring.  The
 buffer is displayed according to `iswitchb-default-method' -- the
 default is to show it in the same window, unless it is already visible
 in another frame.
 For details of keybindings, do `C-h f iswitchb'.

An emacs command for incrementally switching buffers as you type in a substring of the buffer name. To make this work:

 (require 'iswitchb)
 (add-hook 'minibuffer-setup-hook 'iswitchb-minibuffer-setup)
