Thanks for the summary; as I said I handn't looked closely. I was thinking

this can leave your computer open to the world. Ideally, it

Hmm; so the trick here is that if you start recursive-edit, then when
the zle -F handler executes the special parameters from the surrounding
(original) ZLE context are still defined in the handler?
I'm pretty sure this is an unintentional side-effect of recursive-edit,
and now that you've pointed it out we need to decide whether there is
(a) any reason this shouldn't continue to work, or (b) whether it ought
to be necessary, i.e., why the handlers can't always have ZLE context.

If deactivation is accomplished by changing a key binding, then this will
"just happen" for e.g. vi mode when the vicmd keymap replaces the one
used by recursive-edit. If it's deactivated another way, keymap+widget
won't help, but won't hurt either.

Only with "print -z" which still requires "zle get-line" at some point

I don't think so, but PWS may know better.
} - Can the keymap+widget feature be used outside recursive-edit?
Yes, as long as you created the keymap with "bindkey -N newkeymap main"
after initializing keymap+widget, switching to that keymap will invoke
the widgets whose names are prefixed with the keymap name. (It won't
work for other keymaps like vicmd without extra effort, nor for any of
the "special" keymaps like menuselect.)
recursive-edit is just a convenient way to semi-automaticall push/pop
} ... if thats the case I can simply switch
} keymaps with 'zle -K [keymap]' whenever I need a set of widget hooks to be

} - Whats the best way to modify RBUFFER before a completion widget is

(comppostfuncs would modify the buffer after the completion widget was
It might depend on what you're doing to RBUFFER but the only general
way I can think of is to start off with a normal widget and then call
the desired widget from inside it with "zle completion-widget-name".
If you start out in a widget defined with "zle -C" all of the normal
widget variables are already read-only and you can only affect RBUFFER
by changing what gets passed to compadd.
