@b0rk thanks for working on this, it's great to see work on improving docs for such a well used tool.

I saw your email thread viewer used jwzthreading, and just in case it comes in handy - long ago I also wrote something using that, and there is a bug in that library that loops forever with some threads that end up having cycles. The original repo never got the fix, but I see there's a version at https://github.com/FreeDiscovery/jwzthreading that handles the case I found correctly.

@b0rk this is really good. I didn't know about `which -a` - there's always something still to learn.

I don't know if it's worth adding zsh-specific things, but when I was using zsh I really liked the interactive editing of variables like path via e.g. `vared path`, or append to it with just `path+=newdir`

Being able to just edit the variable and not have to remember to include its previous value, etc. was nice.
