So whoever wrote those tools confused a configurable keybinding with a

I don't believe that the Zap function is a configurable keybinding.  It
can only be triggered by Ctrl+Alt+Backspace.


You believe wrongly. It's the Terminate_Server symbol, and you can bind 
it to whatever you want with XKB.

Now, arguably, a better approach would have been to leave DontZap as the 
default but remove the Terminate_Server entry from the default XKB maps. 
That would let clients rebind it if they want to, which can be done 
without requiring administrative privileges.

I also made a suggestion upstream that to protect Emacs users, the default Ctrl-Alt-Backspace could be left enabled but that it would have to be pressed TWICE in order to kill the X server. This way tools that embed the Ctrl-Alt-Backspace keysequence such as virtualization tools would still work. The user would just have to select it twice from the menu. And this would be a lot more acceptable than just disabling the Ctrl-Alt-Backspace default. Regards, Gerry
