Commenting Out Archive

On the side-bar I want to delete the “Archive” text/link but I don’t like to delete actual code. Is there a way I can just comment that part out so I can get it back in tht future? I assume this is what I need to comment:

<?php } ?>

<?php wp_list_pages(‘title_li=<h2>Navigation</h2>’ ); ?>

• <h2>Archives</h2>

<?php wp_get_archives(‘type=monthly’); ?>

But I don’t know where to put the /* */
