I had been meaning to do this one for a long time, so I put it in
minivend.cfg for the 3.12 demo:

UserTag bar-button Order page current
UserTag bar-button PosNumber 2
UserTag bar-button HasEndTag 1
UserTag bar-button Routine   <<EOR
sub {
	use strict;
	my ($page, $current, $html) = @_;
	$current = $Global::Variable->{MV_PAGE}
		if ! $current;
	$html =~ s:\[selected\]([\000-\377]*?)\[/selected]::ig;
	my $alt = $1;
	return $html if $page ne $current;
	return $alt;
}
EOR

This is called with something like:

			[bar-button srchform]
				<A HREF="[area srchform]">Power Search</A>
			[selected]
				<B>Power Search</B>
			[/selected]
			[/bar-button]<BR>

Perhaps even more interestingly:

			[bar-button page=Renaissance
						current="[value mv_searchspec]"]
    	        <A HREF="[area scan
								di=category
								df=yes
								dl=Renaissance
							]">Renaissance</A>
			[selected]
						<B>Renaissance</B>
			[/selected]
			[/bar-button]

This last one solves the real problem that would be difficult
to solve with static HTML; doing it dynamically based on a search.

It will be in the next beta upload, probably this weekend sometime; but
if you want it sooner it is all right here. Did I ever mention that
I think UserTag is pretty powerful? Thanks to Perl, that is. 8-)
