[imp] Show locale text on a custom made link on top manu!

[Stefanos I. Dimitriou]

Dear all

I just added a custom link on top menu linking to the filter.php page.
It works fine but I Don't Know how to show the locale message (Filters) 
for the link. 
I have used the following in IMP/config/menu.php
   $_menu[] = array(
       'url' =>        './filters.php',
       'text' =>       'Filters',
       'icon' =>       'filters.gif',
       'icon_path' =>  '/horde/imp/graphics',
       'target' =>     '_top',
       'onclick' =>    ''
   );
Anything I have used so far for the text just flashes the message on the screen
i.e 'text' =>       '_(Filters)', or
     'text' =>       '_("Filters")',
Can I do anything to show the locale message?

Thanks
