Interactive Recognition Patterns

[John M Church]

Hi,
I'm interested in providing users a way to open a data file and 
highlight items that are of interest to them that they can change while 
the file's open without having to know how to navigate-to and modify the 
recognition pattern.  Ideally I'd provide them a Tk-based GUI they could 
call via the nedit's shell menu that would change the pattern for them 
and have it take effect immediately.  Is this possible?

I've found one clunky way that requires modifying the nedit.rc file 
after the data file is open.  I run a shell menu command to re-call 
nedit with the -import arg specifying a file containing a changed 
highlightPattern.  Now I have a second nedit window with the new regex 
in-place so when they open the datafile from here the new items are 
highlighted.  This has several cons that I'll explain further if 
anyone's interested.

Anyone have an idea better than mine?  My apologies if I've missed the 
way to do this in the documentation and mailing list archives.
