No problem! If you can afford it, a paper copy of the Pickaxe book is IMO
well worth buying, simply because you can thumb through to the class
reference section and in a couple of pages you have a neat summary of all
the instance methods of Array (or whatever class you're interested in)

I still find it useful - there are occasions when I *know* there's a method
in Hash which does exactly what I want, but I can't remember what it is :-)
