Here's one sequence that you can enter in the Mac's ROM minidebugger
window that can be quite useful:

	SM 0 A9F4
	G 0

This stores an _ExitToShell trap into location 0 and branches to it;
it'll usually get you out of a hung application and back to the Finder.

If there's a chance that the hung application left files open, you should
then perform a Restart, to give the system a chance to close the open
files.  Doing the Restart from the Finder is often preferable to
simply rebooting, as the Restart process unmounts all of your disk volumes,
and saves you the long "check the disk and make sure it's OK" wait
during the smiling-Mac phase of the reboot.
