Is it possible to create nested lists in the WYSIWYG editor?

Question

I'm looking to set up WP for a user that does not know or care about HTML, so I need everything to work in the WYSIWYG editor.

She'll be working on posts that have lots of nested bullet lists, but I can't seem to figure out how to make it work. Any thoughts?

Tabbing didn't work, clicking the buttons didn't work. Hitting 'indent' could be hacked into a solution, but it's certainly not ideal and I don't know how consistent it'll be. I know I can fiddle with the HTML, but like I said, I don't want to get into that. I can copy/paste from Word, but that's a terrible solution.

I'm open to a plugin or alternate editor, though that's not ideal either.
