Something like this? Have a look at Format > Bullets and Numbering....
Thanks Jossi, I thought it would be easy, but I couldn't figure out how to do it.
I did read the "help" for bulleted and numbered lists before I posted here, but that didn't explain it well enough for me to understand how to do what I wanted.
As a further question, the help text "Numbered lists" ends with the comment "For details on creating numbered lists, see the next pages." but I couldn't see links to any "next pages" - perhaps this is where the explanation I was seeking exists . . .
Thanks for your help!

PS: Even with your example, which is exactly what I wanted, it took me a while to figure out that the secret is the "Additional indent" setting. Obvious it is not . . .
