I've just read Enable kill X.org with ctrl+alt+backspace and am really happy, that control-alt-backspace no longer kills my X-Server. However, I'd like to have a way to kill it; it just should be something more complicated than what I type by accident ten times a day.
Is there a way to define an own binding for the kill?
I'd like to use control-alt-meta-shift-backspace or alike and from the line
Option "XkbOptions" "terminate:ctrl_alt_bksp"
it's not obvious how to do it (unless it is "terminate:ctrl_alt_meta_shift_bksp" which doesn't seem to work).
