TIM (Long May He Connect) has blessed us with an online searchable index for the entire Help Facility. It's easy to use, though it requires some client or other that can handle forms; recent versions of Mosaic come to mind.
Composing searches for the Help Facility Index takes a little practice and luckily for you, there's an information file on how to compose them.
There's even an overview of how the Help Facility is arranged.
And, of course, you could always connect to TIM directly and just type HELP once you've logged on. By the way, the entire Help Facility is in a constant state of flux, with new Help Files being added or edited every week. Be sure to check the menus every once in a while to see if anything new has come you way.
Mail regarding the Help Facility should be set to email@example.com RE: HEY DOCUMENT COW.
