Textmate has a very nice file-opening and switching command mapped to
Apple-T which allows a "fuzzy" string to be entered to so the user can
switch to a file which may or may not have been opened yet. For example,
type "elp" and files in the "project" such as "elephant" and "elope" will
both show up as possible matches. Is there something similar for emacs? I
looked into Icicles which has a fuzzy matching mode, but emacswiki says it
does NOT do filename completion.
