Any way to alphabetize my Categories list on right-hand side?

Cool – thanks – I’m not an expert, so if you don’t mind me asking, where do I put that code, in the Sidebar.php section? Thanks again!

OK – cool – I hate to bother, but if you could indulge me on this one….I am working with an already existing theme with this code for showing the categories on the side:

<?php include (TEMPLATEPATH . '/options/options.php'); ?><div id="sidebar"><?php include (TEMPLATEPATH . '/domtab.php'); ?> <?php if (function_exists('fc_feedcount')): ?><div id="rss-feeds"><div id="rss-block"><a href="#">&nbsp;</a></div><div id="rs-count"><?php fc_feedcount(); ?></div></div><?php endif; ?><?php include (TEMPLATEPATH . '/advertisment.php'); ?><?php if($tn_mz_aside_post_status==yes): ?><div id="more-headline"><?php $my_query = new WP_Query('category_name='. $tn_mz_aside_post_cat . '&' . 'showposts='. $tn_mz_aside_post_sum);while ($my_query->have_posts()) : $my_query->the_post();$do_not_duplicate = $post->ID; ?><div class="side-feat"><?php $values = get_post_custom_values("featured-images");if ( is_array($values)) : ?><div class="span-img"><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><img src="<?php echo "$values[0]"; ?>" alt="<?php the_title(); ?>" /></a></div><?php endif; ?><h1><?php the_title(); ?></h1><?php the_excerpt_aside(); ?></div><?php endwhile;?></div><?php endif; ?><?php if($tn_mz_side_thumbnail_status==yes): ?><div id="my-wp-theme"><div id="theme-slot"><ul><?php $my_query = new WP_Query('category_name='. $tn_mz_side_thumbnail_cat . '&' . 'showposts='. $tn_mz_side_thumbnail_sum);while ($my_query->have_posts()) : $my_query->the_post();$do_not_duplicate = $post->ID; ?><?php $values = get_post_custom_values("themes-images");if ( is_array($values)) : ?><li><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><img src="<?php echo "$values[0]"; ?>" alt="<?php the_title(); ?>" /></a></li><?php else : ?><li><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><img src="<?php bloginfo('template_directory'); ?>/images/no-image.gif" alt="<?php the_title(); ?>" /></a></li><?php endif; ?><?php endwhile;?></ul></div></div><?php endif; ?><div id="widget-sidebar"><!--[if !IE]>SIDEBAR WIDGET<![endif]--><div class="bar"><?php if ( !function_exists('dynamic_sidebar')|| !dynamic_sidebar(1) ) : ?><?php if(function_exists("wp_theme_switcher")) : ?><h3><?php _e('Themes'); ?></h3><?php wp_theme_switcher('dropdown'); ?><?php endif; ?><h3><?php _e('Categories'); ?></h3><ul class="list"><?php wp_list_categories('orderby=id&show_count=0&use_desc_for_title=0&title_li='); ?></ul><?php endif; ?></div><!--[if !IE]>SIDEBAR WIDGET 2<![endif]--><div class="bar"><?php if ( !function_exists('dynamic_sidebar')|| !dynamic_sidebar(2) ) : ?><!--[if !IE]>sample no list sidebar list<h3><?php _e('Archives'); ?></h3><ul class="nolist"><?php wp_get_archives('type=monthly&limit=12&show_post_count=0'); ?></ul><![endif]--><h3><?php _e('Archives'); ?></h3><ul class="list"><?php wp_get_archives('type=monthly&limit=12&show_post_count=0'); ?></ul><?php endif; ?></div></div></div>

Can I just place the code you showed me somewhere in there, in the appropriate place?

THANKS AGAIN!!
