Is there something here documenting the prompting language, i.e. parentheses, brackets, etc?

It looks like (this works:1.2) for emphasis, just like SD15, but does everything else from SD15 carry over? For example can I do something like [cat|dog] to get somethinig that vaguely looks like a catdog? And are there any additional features not in SD15?
