As title. Given that I'm already in insert mode and there is some insert mode function. Inside the function, I want to insert a space by command, how?

  • if you are inside an insert mode function just returning ' ' does not work (e.g. returning a space)? May 18, 2022 at 11:22

something like the following snippet works while in Insert Mode and typing <C-o>:call Testing()

function! Testing()
  echom 'testing...'
  exec 'normal! i '
  echom 'done.'

(added it to my .vimrc for testing)
