In Insert and command-line mode using CTRL-K <hit-the-Key> mostly works.
You could make something that enters the key on the command line and
use getcmdline() to get the key name.
This mostly works, but breaks certain contexts (i.e. in the middle of
echo'ing a sequence of stuff):
function! s:special_key_name( key )
exe "normal :let special_key_name='" . "\<c-k>" . a:key . "'\<CR>"
return special_key_name
endfunction

Why do you need a function to get the key name from a key code? What
are you going to use that name for? Why didn't you have the name
already?
When I receive a special key string from getchar(), I often store it,
and want to display it later in recognizable format. There are also
cases when I store the input'd key string into a configuration file,
in which case the "\<keyname>" would be the most portable way to do
this.
In general, it seemed like strtrans() should be the function handling this.
