question about keybinding

[Andy Spiegl <zsh.Andy@xxxxxxxxx>]

Hi,

I'm basically using the emacs-keybinding and have my wordchars set to:
 WORDCHARS='*?_-.[]~=/&;!%^(){}<>+'

But sometimes I'd like to behave emacs-(back|fore)ward-word differently
so that it doesn't jump over dots.  Let's say when I additionally press
SHIFT together with meta-b.  I've been pondering but I can't think
of a simple way to set it up so that the WORDCHARS setting changes
depending on which key I press.

Does any of you gurus have an idea?
Thanks so much,
 Andy.
