Hello,
I'm trying to map C-1 to some command (:tabn 1cr) and
unfortunately it's not working :( I'm trying on linux (where this
mapping for mrxvt works) and windows...
Have you any clue why it's not working?
With regards,

It's not working because it's not defined.
The following Ctrl + printable key combinations are defined, and since they
date back to a time when keyboards had neither F keys nor arrow keys, nor even
Tab or Backspace, sometimes not even an Enter key, they are portable across
all ASCII-based hardware and software flavours AFAIK:
Ctrl-? 0x7F
Ctrl-@ 0x00
Ctrl-A 0x01
Ctrl-B 0x02
...
Ctrl)Y 0x19
Ctrl-Z 0x1A
Ctrl-[ 0x1B
Ctrl-\ 0x1C
Ctrl-] 0x1D
Ctrl-^ 0x1E
Ctrl-_ 0x1F
Ctrl-a to Ctrl-z : same as Ctrl-A to Ctrl-Z
A Ctrl function is also defined for most of the non-printable keys, but the
keycodes are implementation-dependent (they vary from one console terminal to
the other).
Ctrl + other printable keys is not defined. (Programs reading their keyboard
in raw mode may sometimes nevertheless identify them, but Vim uses cooked
mode.)
OTOH, Alt + printable key is usually defined, but in most cases it collides
with symbols or letters-with-diacritics in the range 0xA0-0xFF.
If you want to define portable key mappings, I recommend choosing among F2 to
F9, F11, F12, and Shift-F1 to Shift-F12. If you need more, try multikey
mappings and/or Ctrl-Alt-a to Ctrl-Alt-Z. Some of the latter, however, might
be pre-empted by your OS and never make it to Vim.
Best regards,
Tony.
