funny, I don’t think you can do that in vim - I tried 50 times or so haha, in nvim you can actually rebind the mapping :map <C-c> :echo “hello”<CR>

or perhaps more usefully :map <C-c> <esc>

having said that though I was impressed by the default actions for <C-c> in nvim for example autoindenting on leaving insert mode in vim would stop the operation whilst nvim does not

basically in nvim it seems to behave exactly like <esc>
