Huh?  I added a new user account to my debian/testing system with
no further customization whatsoever and renamed xorg.conf and
/etc/default/keyboard.  Then I started X as this new user, opened
a xterm and a rxtv-unicode, started emacs -Q -nw, did C-h k
(describe key) and hit C-: which is Shift-Control-. on a german
qwertz keyboard.

It says

: runs the command self-insert-command, which is an interactive
built-in function in `C source code'.

I never used a terminal emulator which would let me use
Shift-Control key combos.  Actually I would be very interested in
working Shift-Ctrl key combos.

ATM I can't test with different (left, right) control keys since
I'm at a MacBook, there sadly is only one control key.

You are able to type C-: in an emacs running in a terminal emulator?
