^^ correct, and a parent's key can also change the child's owner key (not yet, but eventually)
Wow
So I have a new question.
the vote belong to the account name, or owner key, or active key?
Votes belong to deposits (shares), not accounts.
Sorry I am not write it clearly.
I mean, when I vote 10000 shares for toast(with owner key Key1, and active key Key2)
these votes belong to name toast, or Key1, or Key2?
