Confused about nested bullets

Hi there. Is there a way to create nested bullets in Stickies? I can't figure them out for the life of me. Usually, in text editors you can press Tab to nest a bullet, but in Stickies that just inserts a tab character after the bullet. I've tried all manners of hotkeys involving the Tab and Right Arrow keys and none of them worked. I can't find the relevant info in the manual, either.

You can take a look here :

Thank you so much!
