@Robin — No, ‘Ctrl’ isn’t required.

I’ve used the ‘Alt+SysRq+r e i s u b’ sequence before on a couple of different linux systems. Usually because it wouldn’t respond to other nicer shortcuts like Ctrl+Alt+Backspace (kill X server) or Ctrl+Alt+Delete (restart computer or open shutdown dialoge, depending on your environment).
I have also gotten into Really bad situations where even ‘Alt+SysRq… didn’t work, which is sad because I have to hard-shutdown the computer.

Are you quite sure you don’t need to press ‘Ctrl’, too? All previous explanations of this feature I have seen require ‘Ctrl’ + ‘Alt’ + SysRq’ + additional keys. ‘Alt’ + SysRq’ should, thanks to the function of the Print Screen feature, only lead to a screenshot to be dumped.

In addition, most notebook users will additionally have to press the Fn key to be able to access SysRq. Yes, a third hand comes in handy.
