To be honest I'm having trouble figuring it out but I'm still chewing on 
it.  Learning curve here is vertical.

That's where I want to be but I have no idea how to get into the 
widget.  Never been near a widget yet.

Well, writing it to history is no problem, the thing is to be able to 
insert the unexpanded tail into it at the appropriate place.  No idea 
what being in the widget means.  This is absolutely new to me.

Ok, I can copy that and give it a go.  Probably still want _execute cuz 
it does some other stuff too, and it's no problem, so long as I have 
that tail.  Will chew on that tomorrow. Tx.
How do we access the users archives?  I should know that.  Any chance of 
doing this kind of thing in preexec()?  So it's always available? Most 
of my functions go thru the same trouble, so having general access to 
that BUFFER would be ideal.
