There's no need for the $A part of that, $$ returns an array already.

As the docs say, it finds elements according to CSS selectors.
Specifically, $$ supports CSS2 and a fair bit of CSS3, so you type the
same selectors you'd use for CSS. So for instance:
var inputControls = $$('.FokusControls');
Prototype's documentation is a bit messed up right now, but it may be
useful to have a read through the old docs[1] and the new ones[2] (the
old docs still have information that hasn't been migrated to the new
docs yet; people are working on it).
