What about special key sequences like Ctrl+Alt+Delete on Windows, or Ctrl+Alt+F-key on most Linux distros?

Or even more crazy special commands like Alt+PrintScreen+REISUB?

Alt+Ctrl+Delete was special-cased as an unforgeable sequence to access the security screen in Win NT, with special provisions down to BIOS level IIRC. (Else credentials stealing becomes too easy.)

REISUB is for truly exceptional circumstances; I used it 2-3 times in 20 years of using Linux on desktop.
