ctrl-alt-end zum herunterfahren

In /etc/console-tools/default.kmap.gz:

keycode 110 = Insert
altgr control keycode 110 = KeyboardSignal?
control alt keycode 110 = KeyboardSignal?

and in /etc/inittab:

# What to do when CTRL-ALT-DEL is pressed.
ca:12345:ctrlaltdel:/sbin/shutdown -t1 -a -r now
# Action on special keypress (CTRL-ALT-INS).
kb:12345:kbrequest:/sbin/shutdown -t1 -a -h now

Although, for „-End“ you need „keycode 107 = Select“
