in thread what does goto ""; mean?

Well, in GNU sed, for example, you can jump to an empty label:

For example, echo bungee | sed ':;s/\(.\)\(.*\)e/\2\1/;t;' prints ngub.

UPDATE: I didn't give an answer to your question, so here it is. I saw that you can create an empty label (you can't), and wondered how to jump there. A simple goto; is not enough. So I tried goto "";.
