Sorry for answering so late.

In Insert/Replace or Command-line mode, Ctrl-K is a prefix key, used to
usher either a digraph (when followed by two printable keys) or the <>
notation for one non-printable key. The first of these two functions can
also be used for the argument of some Normal-mode commands such as r F f T t

See
:help i_CTRL-K
:help c_CTRL-K
:help 24.9
:help digraph.txt

If 'showcmd' is on (which is the default on Windows but not on Unix),
hitting Ctrl-K should display ^K near bottom right of the screen,
telling you that something more is expected.

AFAIK, this key is not remappable. Don't know if it's intended or an
oversight, but the help says that its operands are not considered for
mapping.

Best regards,
Tony.
