To create sparse trees and special lists with selection based on properties,
the same commands are used as for tag searches (@pxref{Tag searches}), and
the same logic applies. For example, here is a search string:
@example

+work-boss+PRIORITY="A"+Coffee="unlimited"+Effort<2+With=@{Sarah\|Denny@}
@end example

finds entries tagged @samp{:work:} but not @samp{:boss:}, which
also have a priority value @samp{A}, a @samp{:Coffee:} property with the
value @samp{unlimited}, an @samp{Effort} property that is undefined or
empty, and a @samp{:With:} property that is matched by
the regular expression @samp{Sarah\|Denny}.
If the comparison value is a plain number, a numerical comparison is done,
and the allowed operators are @samp{<}, @samp{=}, @samp{>}, @samp{<=},
@samp{>=}, and @samp{<>}. If the comparison value is enclosed in double
quotes, a string comparison is done, and the same operators are allowed. If
the comparison value is enclosed in curly braces, a regexp match is
performed. So the search string in the example finds entries tagged
@samp{:work:} but not @samp{:boss:}, which also have a priority value
@samp{A}, a @samp{:Coffee:} property with the value @samp{unlimited}, an
@samp{Effort} property that is numerically smaller than 2, and a
@samp{:With:} property that is matched by the regular expression
@samp{Sarah\|Denny}.

@item @file{org-publish.el} by David O'Toole
This package provides facilities for publishing related sets of Org
files together with linked files like images as web pages. It is
highly configurable and can be used for other publishing purposes as
well. As of Org version 4.30, @file{org-publish.el} is part of the
Org distribution. It is not yet part of Emacs, however, a delay
caused by the preparations for the 22.1 release. In the mean time,
@file{org-publish.el} can be downloaded from David's site:

@cindex @file{org-mouse.el}
@item @file{org-mouse.el} by Piotr Zielinski
This package implements extended mouse functionality for Org. It
allows you to cycle visibility and to edit the document structure with
the mouse. Best of all, it provides a context-sensitive menu on
@key{mouse-3} that changes depending on the context of a mouse-click.
As of Org version 4.53, @file{org-mouse.el} is part of the

them have either been integrated into Org by now, or they can be found in the
Org distribution, in the @file{contrib} directory. The list has gotten too
