It might be either a key on its own or printed on the side of PrtScr.

You almost always want to end this with 'b' (reboot) rather than 'o' (off).
The 'r' is pointless here (as you're not going to use the system anymore),
'e' and 'i' are unlikely to help.

For stuck X/Weyland/SVGAlib/etc you want 'r'+'k' rather than nuking the
system.
