Confusion about listing all entries of a category on a post page

Hello.

I’m currently migrating my Movable Type blog onto WP 2.5.1 and everything is going smoothly except for one issue that I’m unable to find a solution for. I’m guessing the answer is so simple that I’m missing it completely. (I’m confused if it is a get_posts or a wp_get_archives issue, so any help is very much appreciated, especially if I overlooked a previous entry on this.)

One an individual blog page, I’m trying to show the individual blog entry (no problem there) but also all the other entries in that category, by title, such as:

“You are in the single_cat_title section. Here are all the other entries in that category:
name of entry
name of entry
name of entry”

Thanks in advance.
