About <C-Tab>: most terminals send <Tab> when you enter <C-Tab>, so vim cannot
distinguish it.
About <C-FN>: though my terminal sends different key sequences for <FN> and
<C-FN>, vim is not able to recognize it as <C-FN> and has no option like
set <F1>=^[OP
for <C-FN>. I do not know, why vim has
set <M-a>
and does not have
set <C-F1>
, but you may still map <C-F1> by yourself:

let s:TermKeys={}
if !has("gui_running")
if $TERM==#"xterm"
let s:TermKeys["<C-F1>"]="\e[11;5~"
let s:TermKeys["<C-F2>"]="\e[12;5~"
<...>
let s:TermKeys["<C-F12>"]="\e[24;5~"
endif
endif
function s:GetTermKey(key)
return get(s:TermKeys, a:key, a:key)
endfunction
function MapTerm(mapcmd, flags, lhs, rhs)
execute a:mapcmd." ".a:flags." ".
\substitute(a:lhs." ".a:rhs, '<[^>]*>',
\'\=s:GetTermKey(submatch(0))', 'g')
endfunction
call MapTerm("noremap", "", "<C-F1>", ":h<CR>")
