[BobLewiston]

The documentation I've found is a little hazy on this subject, so it's time to fire off yet another no-doubt ignorant question:

Is "throw" intended exclusively for the following scenario: Control is transferred out of a try block via a method call, and code in the called method then detects an exception, so the called method uses "throw" to transfer control back to the appropriate catch block associated with the original try block?

The 'throw' keyword is for the programmer to specify that execution should no longer continue in the current method because of some error (null variable, non-existant file, etc.). When an exception is thrown, the CLR walks the callstack until an exception handler (catch block) is found. If one is not found, the program crashes and terminates.
