Interesting...but I pressed <Ctrl-Space>... :)
Mismapped key? Do I have to fix it via Xmodmap?
Keep hacking!

Ctrl-Space is not a portably mappable key. Portably mappable keys are those
which are reliably detected on all platforms. Ctrl + printable keys are
defined as follows (on ASCII systems; I don't know about EBCDIC):
Ctrl-@ 0x00
Ctrl-a 0x01
...other alphabet keys in ascending sequence...
Ctrl-z 0x1A
Ctrl-[ 0x1B
Ctrl-\ 0x1C
Ctrl-] 0x1D
Ctrl-^ 0x1E
Ctrl-_ 0x1F
Ctrl-? 0x7F
In Vim, Ctrl-J also returns a null byte because of the way line breaks are
handled.
On "national" keyboards, Ctrl + nonalphabetic printable keys may be hard to
find on your keyboard (e.g., Ctrl-_ may be on the key which gives _ on a US
QWERTY keyboard, which can be different from the key which gives _ on your own
keyboard). If you don't find them, you can always remap them, e.g. ":map <F10>
<C-_>".
Ctrl + non-printable keys (like Ctrl-Up or Ctrl-F1) is mappable too unless
your OS snatches them before they get to Vim (my window manager snatches
Ctrl-F1 to Ctrl-F12 so I never see them in gvim or in vim-in-konsole); but
Ctrl + other printable keys is not defined; Vim may see it or not, or see it
as the same as something else, depending on your system and on its keyboard
driver. On my system gvim sees Ctrl-space as just a plain space.
