ls g^h

ls g^h

[zzapper]

Hi
When I mistyped a
^g^h   type substitute 
with
g^h

I was surprised to find that it matched 
a directory "growth"
eg
ls g^h   would list the directory

what functionality/fng is that? (hope it's not me being dumb)

In zshguide.pdf (around page 227) there is some discussion on  
EXTENDED_GLOB: it's part of that.
g^h is the pattern  "everything starting with g but not matching "h"  
exactly ". You happened to have exactly
one file starting in 'g',  I suppose (the final h seemingly matching  
is coincidental).
E.g. if I have 2 files "good" and "growth" then g^h matches them both,  
with EXTENDED_GLOB set.
In short: it becomes a globbing pattern by virtue of the presence of ^

The conventional zsh way would be?
ls *.*~*.txt
rm -rf Pictures_of_*~*beautiful_flowers

There is a small difference between ^ and ~ in this context. ~ matches
the whole globbed string while ^ only matches a single element, IIRC
at least. So you can do a/^foo/blue which is not the same as
a/*/blue~foo/blue but rather a/(*~foo)/blue, again IIRC.
