Yes it does, but keep in mind it returns a collection of elements, not
a single one. Even when your selector only matches a single element
(like $$('html body')).

Yes, but on individual items in the returned collection, not the
entire collection itself.
// hide every div with a class of "custom-class"
$$('div.custom-class').invoke('hide')
// iterate over the same collection, updating the *first* paragraph
with new text
$$('div.custom-class').each( function( element ){
element.down('p').update('I was here');
});
