Hmhm.

With the same tag (or without using group-names) they'd be in the same 
group.  But of course we can also make the other things take
precedence or give them all the same precedence so that users who use
more than one mechanism see all of them at the same time.  And of
course we can use different tags leaving it to the user's tag-order
setting.

I have sometimes, too.  I need to remember it more often...

The problem I have with the current way to specify URLs is not the
repeated tabs, it's that it much more complicated to set up then
needed (for some, like the original poster).

But anyway, this is a good idea.  I know I thought about this some
time ago and thought I mentioned it here (but I'm not sure).

The problem is to find out when to stop.  And that the only way to
implement it I can currently see is some kind of wrapper around
_main_complete.  Although that could be just another widget, that
might be bound to TAB.

Hm.  Something as simple as:

    zle -N frob

    frob() {
      zle complete-word
      while [[ $_lastcomp[nmatches] -eq 1 && $RBUFFER[-1] != [[:blank:]] ]]; do
        zle complete-word
      done
    }

already does part of it, though not nicely.

Bye
 Sven
