In org-mode refresh the numbers in a numbered list

Question

I am in Org Mode and I have a numbered list.

1. Hello
2. World
3. How
4. Ya
5. Doing?

I remove the first entry to get the following.

2. World
3. How
4. Ya
5. Doing?

Is there a shortcut to refresh the numbering, and to end up with the following?

1. World
2. How
3. Ya
4. Doing?

Answer 1

With point anywhere in the list, press C-cC-c.

It runs org-ctrl-c-ctrl-c which does many things depending on the context, see its documentation.
