Thanks Mike, this works wonderfully.

To have an "object", like in my case an [include] of different style search
engines that persist and are switchable even on flypage, you do the
following...

NOTE: WRT searchset and smode, these are unique to my implementation, you
may need to change accordingly.

1. One line global usertag foo.tag:
       UserTag flycode Routine sub { return $Vend::Flypart }


2. Put this [set] and [calc] on every page you need it on.
   It should work in the template, in a page, and in my
   case an [include] in the top template.

    # sets the mv_click action
    [set searchset]
     [seti smode][cgi smode][/seti]
    [/set]

    # this will insure the flypage item gets translated into the mix
    [calc]
	$Scratch->{page_arg} = $Tag->flycode();
	unless ($Scratch->{page_arg}) {
 	$Scratch->{page_arg} = $Tag->var('MV_PAGE', 1);
	}
	return;
    [/calc]


3. The buttons that controls this "switching":

   	<A HREF="[area
			href="[scratch page_arg]"
	            form="
		    	mv_click=searchset
			mv_action=return
                  smode=             # take note smode
			"
	  ]">switch to simle mode</a>



      <A HREF="[area
			href="[scratch page_arg]"
	        	form="
			mv_click=searchset
			mv_action=return
                  smode=adv          # take note smode
			"
	  ]">switch to advanced mode</a>

4. Then, obviously these controls need to control something. In my case
   I have in my top template;


   [if scratch smode eq adv]
     [include templates/components/imode2.txt]
     [else]
     [include templates/components/imode1.txt]
     [/else]
   [/if]


NOTE: (optional)
   With an addition of other scratch criteria, you can really get fancy.
   I have an advanced mode, as well as a simple mode, for each: images,
   audio and video. "smode" (simple or advanced) persists across all pages
   until changed. The "type" of engine (image,audio,video) is controlled
   by a scratch in the meta head, which by the way is a very cool way to
   control appearance. In your template, where it says Page settings add:

   searchtype:
	description: search type change to
	options:

      note: where searchtype is foo. Now nest your [if] statements
            accordingly.

----------------------
These can also be included in account.html or similar to have registered
user "settings" that will activate upon login.
