I just changed

#RET##RET##RET##RET##RET##RET##RET##RET##RET##RET##RET##RET#

to

|RET||RET||RET||RET||RET||RET||RET||RET||RET||RET||RET||RET|

My settings were

FInd: #RET#
Replace: |RET|

Search Syntax: Simple Matching

Checked Options: Ignore Case, Wrap Search

Everything else unchecked.



I was going to attach an image of the panes, but thought better of 
that. =:O


All the documentation appears to be in Japanese, seriously.

I used to use grep and Perl regex a bit -- as built into Nisus, BBedit 
and some other editor for OS 9 -- but am certainly no expert in it. But 
I am working on help text for the various switches for TeXShop.


 From here down or more than you asked for:

For limited help with the Perl OS X syntax go to the terminal and enter:

man perlrequick
     for Perl regular expressions quick start

man perlretut
     for Perl regular expressions tutorial

man  perlre
     for Perl regular expressions, the rest of the story

These are as useful/unuseful as most man pages, being a little cryptic.


Also this is a pretty good site for learning regex:
http://www.regular-expressions.info/


Also the book *Mastering Regular Expressions* by Jeffrey E. F. Friedl 
(O'Reilly) is very good, but way overkill for my needs.
