Yes !!!
That's it !
But know, how can I include reverse ;-) ?
I've tryed :
<a href="<dtml-var URL1>?skey=titre&rev=">Title</a>
<a href="<dtml-var URL1>?skey=author&rev=">Author</a>
<a href="<dtml-var URL1>?skey=bobobase_modification_time&rev= reverse">Last 
modification</a>

<dtml-if "REQUEST.has_key('skey')">
<dtml-else>
<dtml-call "REQUEST.set('skey', 'bobobase_modification_time')">
<dtml-call "REQUEST.set('rev', ' reverse')">
</dtml-if>

<dtml-in "objectValues(['article'])" size=3 sort_expr="skey+rev" 
start=query_start>

But it just work with title and author (rev=none) but not with modif_time 
(rev=' reverse').

Can you help me ?
