The trouble with changing the global WORDCHARS is that it then affects
every widget. I like `/' included for things like copy-prev-word but not
for word deletion so I use this:

tcsh-backward-delete-word() {
  local WORDCHARS="${WORDCHARS:s@/@}"
  zle backward-delete-word
}
zle -N tcsh-backward-delete-word

Zsh allows you to define your own widgets with shell functions like this
so you may be able to translate other things you're used to from tcsh.

Those two widgets annoyingly don't allow you to navigate up and down in
multiple line commands so you may prefer to try `up-line-or-search' and
`down-line-or-search' which are similar. They also have their faults
though because they only use the first word on the current line in their
search. Ideally, these will be replaced with more primitive widgets
(e.g. just up-line) so that I can write one which works exactly as I
like in a shell function.
