There was some side discussion about prompt themes being unmaintained
and therefore unsuitable for this.  My take is that we should find a
way to put some effort into maintaining it.  We did just have a few
patches for it, so I personally would be fine with this going into a
theme.

Also, won't this by default print everything that's already in $key if
by some magic (/etc/zsh* or ~/.zshenv ?) it does already exist?

There was a side discussion about this, too.  The default WORDCHARS
acts like the stty driver, emptying it works more like emacs.

I don't recall what difference being in the menuselect keymap makes here.

Yeurgh.  Agree, avoid bindkey -s.

Again, previously discussed ... the man page recommends specifying
both halves because of the -U option.

I tend to agree.
