Hi Rustom,

Please report Icicles bugs (or questions) using `M-x icicle-send-bug-report'.
Use the latest Icicles files, and specify your Emacs version in the report.
Preferably, send a recipe to reproduce the problem, starting with `emacs -Q'.

Wrt your question -

I'm not sure just what you tried. I think you're referring to the tip on this
page about using `\W$' in an input regexp, to match only directories:
http://www.emacswiki.org/emacs/Icicles_-_Special_Characters_in_Input_Patterns

Keep in mind that this is relevant only for regexp completion (aka apropos
completion, aka `S-TAB'). (And only in Icicle mode, obviously.)

Example:

Suppose that the pattern `foo' has several apropos completions, including some
ordinary-file names and some directory names (subdirectories of the current
directory).

Then this will match all of those files and directories:

C-x C-f foo S-TAB

But this will match only the (sub)directory names:

C-x C-f foo\W$ S-TAB

And this will match all of the (sub)directories (and only directories) in the
current directory (`default-directory'):

C-x C-f \W$ S-TAB

If that is not what you see, or if you need further clarification, you can email
me off list.
