Help >> term_group >> How to change the value

I’m using (read: testing out) the plugin: http://blog.efrees.com/alpha-s-categories-widget-for-wordpress.html

It allows for sorting category via the term_group. Sounds like a great way to have some custom control of the sort order. (Btw, anyone have any experience with this PI and 2.9.x?)

I’ve read: http://codex.wordpress.org/WordPress_Taxonomy

Now, I’ve been known to be a bit slow at times but it’s still not clear to me how I can edit the terms group. Can I edit the terms group? How do I access it? I think you get the point – term_group looks like it;’ll help but I have no idea how to best take advantage of it.
