I want to remap
<C-x> in insert mode (I do not use the completion commands via this key). This is what I tried:
inoremap <C-x> <Esc> :x <Enter>
inoremap <C-x> <C-o> :x
Both variants are accepted by vim, but have no effect. When I execute
:imap <C-x> I get:
<C-X> * <C-R>=<SNR>27_ManualCompletionEnter()<CR>.
I also tried to remove the default mapping:
E474: Invalid argument.
So it seems that
<C-x> is kind-of hard wired into vim and cannot be remapped. Is this correct or is there a way to achieve this?
