Thanks, I'll install that.

I wouldn't know you were new to zsh if you didn't say so; the code looks
as good as anyone's. The one thing I would suggest is to use the
${BUFFER[(i)$char]} syntax in the 'for' loop, which should translate to
a strchr() or strstr() call at the C level. (There's also the
${(ps:$char:)BUFFER} syntax, but I'm not sure it gains you anything.)
Also, three minor points:
- With recent zsh, WARN_CREATE_GLOBAL complains:
(anon):1: scalar parameter ZSH_JUMP_TARGET_CHOICES created globally in function (anon)
(anon):2: scalar parameter ZSH_JUMP_TARGET_STYLE created globally in function (anon)
The fix is to declare these parameters either global ('typeset -g') or 'local'.
- You could use 'region_highlight+=("foo bar baz")' to append to the array.
- You might use an 'always' block to restore $orig_region_highlight.
Thanks again!
Daniel
P.S. Perhaps you could throw a LICENSE file into that repository?
