Key combination to force CLEAN shutdown/restart ?

I don't think there's any key combination to force a CLEAN shutdown or restart without any questions asked.

CTRL-CMD-EJECT does a restart with no questions.

Add OPT to that for a shutdown (CTRL-OPT-CMD-EJECT)

To reset SMC for Macs that do NOT have a removable battery:

Hold down control-option-shift & power keys simultanelously, all at once. Release all keys. Press power button to restart.
