Would that work?
maybe. You'd need to look at XKB's compat capabilities there. Anyway - that's taking the hard way out. your claim was that CAB is too easy to hit. So disable it - it could be easily done at runtime through xkb options. Or put it on ctrl-alt-shift-F12 or something. Alternatively, have a client listen to CAB, load the normal xkb behaviour, pop up a dialog "if you want to kill the server, hit CAB now".

Ha, serves them octopodiformes right for having 2 fingers less than us! There is a thing such as cost/effort. stop your pet sitting on the keyboard, or disable zap. > 3. are kbd and evdev each able to detect such a key combination? both are designed to handle key events - yes. > 4.

Do most users know how to press multi-letter key combinations? Depends on your definition of "most" and of "users". I know a fair few that would go looking for a post box when you start talking about multi-letter combinations.
