The problem with X is that there are so many ways and places to do it
and higher-level programs can hide the lower-level settings.

X has a "xkb" system (see xkbcomp manpage and elsewhere) that lets you
mess with low level stuff, which can be handy to enable special buttons
on fancy keyboards.

Many X programs (eg, Xemacs) can be configured with custom keys and
key combinations.

The window manager fvwm2 seems fairly easy. This allows
ctrl-alt-delete to do something (defined in the config file)

      Key Delete A CM something
                 ^ ^^- Alt
                 | +-- Ctrl
                 +---- Any context
