Re: I'd emulate Ctrl-Space keypress and CLI with Esc using map

Sorry, I may confuse you.
Fedora 28 vim is 8.0.1704 which is built by distribution not mine.
vim-minimal does not send Ctrl-\ and Ctrl-G but vim-enhanced can send them.
I didn't notice vim-minimal does not support .vimrc fully.
Now I use vim-enhanced and that problem is fixed.

vim-minimal is built with:
%configure --prefix=%{_prefix} --with-features=small --with-x=no \
--enable-multibyte \
--disable-netbeans \
%if %{WITH_SELINUX}
--enable-selinux \
%else
--disable-selinux \
%endif
--disable-pythoninterp --disable-perlinterp --disable-tclinterp \
--with-tlib=ncurses --enable-gui=no --disable-gpm --exec-prefix=/ \
--with-compiledby="<bugzilla@redhat.com>" \
--with-modified-by="<bugzilla@redhat.com>"

vim-enhanced is built with:
configure --with-features=huge \
--enable-pythoninterp=dynamic \
--enable-python3interp=dynamic \
--enable-perlinterp=dynamic \
--disable-tclinterp --with-x=yes \
--enable-xim --enable-multibyte \
--with-tlib=ncurses \
--disable-gtk3-check \
--enable-gtk3-check --enable-gui=gtk3 \
--with-compiledby="<bugzilla@redhat.com>" --enable-cscope \
--with-modified-by="<bugzilla@redhat.com>" \
%if "%{withnetbeans}" == "1"
--enable-netbeans \
%else
--disable-netbeans \
%endif
%if %{WITH_SELINUX}
--enable-selinux \
%else
--disable-selinux \
%endif
%if "%{withruby}" == "1"
--enable-rubyinterp=dynamic \
%else
--disable-rubyinterp \
%endif
%if "%{withlua}" == "1"
--enable-luainterp=dynamic \
%else
--disable-luainterp \
%endif
--enable-termtruecolor

Now my another problem is that I cannot send Ctrl-Space key to xterm or gnome-terminal but not vim.
I tried:

nmap <F4> <C-Space>

and

nmap <F4> :call feedkeys("\<C-Space>")<CR>

but gnome-terminal receives F4 key only with either nmap when I debugged gnome-terminal.

I tried 8.0.1704 of Fedora 28 and 8.0.1766 of Fedora 29 but vim, vimx, gvim failed to receive the key events.
I thought I might mistake the syntax.
Or do you mean the syntax is correct and you can send Ctrl-Space key with the above nmap?

Thanks
