Remove buttons for sorting

Hello,
I dont need this "name-price-popularity-date" buttons.
Can I hide them?

For others in your position. Would you mind posting the solution rather than just closing the thread?
I erased these lines:

 'sort_alternatives' => array(
'relevance' => language::translate('title_relevance','Relevance'),
'name' =>language::translate('title_name', 'Name'),
'price' => language::translate('title_price','Price'),
'popularity' =>language::translate('title_popularity', 'Popularity'),
'date' => language::translate('title_date','Date'),

in: pages/category.inc;php
     pages/manufacturer.inc.php
     pages/search.inc.php
     vqmod/vqcache/vq2_pages_category.inc.php

This works for me, but I do not guarantee anything for another installation:
save before your files.

Or you could just delete them straight in the view e.g. includes/templates/default.catalog/pages/category.inc.php which would not tamper with the core.
