Formatting Marks (editing symbols)

OK, this is probably a really dumb question. I keep my view in Word to show formatting marks. Does anyone know where I can get a list of what each formatting (editing) symbol means? I know what many of them mean, but there’s some I’m not sure andit would be really helpful to have a reference. I’ve tried the help files and various searches on MS but not luck. I think I might not be using an accurate enough search criteria. Thanks!
