I can't tab if in insert mode and on a new blank line

See gif. When I enter insert mode on a new blank line at column 0 it won't let me tab. I have the

Here's what my completor section looks like in my vimrc.

That's because you mapped <Tab> to <C-R>=completor#do('complete')<CR> when the popup menu is not open.

So a better way to reserve the default action of <Tab> is to use another mapping for triggering completion:

inoremap <expr> <c-n> pumvisible() ? "<C-N>" : "<C-R>=completor#do('complete')<CR>"

Firstly, thanks for your response.

@maralla I ended up modifying a script I was previously using that I stole somewhere online (don't recall).

This does exactly what I want and behaves the same way that many other editors do now with auto completion.

" Use TAB to complete when typing words, else inserts TABs as usual.  Uses
" dictionary, source files, and completor to find matching words to complete.

" Note: usual completion is on <C-n> but more trouble to press all the time.
" Never type the same word twice and maybe learn a new spellings!
" Use the Linux dictionary when spelling is in doubt.
function! Tab_Or_Complete() abort
  " If completor is already open the `tab` cycles through suggested completions.
  if pumvisible()
    return "\<C-N>"
  " If completor is not open and we are in the middle of typing a word then
  " `tab` opens completor menu.
  elseif col('.')>1 && strpart( getline('.'), col('.')-2, 3 ) =~ '^\w'
    return "\<C-R>=completor#do('complete')\<CR>"
  else
    " If we aren't typing a word and we press `tab` simply do the normal `tab`
    " action.
    return "\<Tab>"
  endif
endfunction

" Use `tab` key to select completions.  Default is arrow keys.
inoremap <expr> <Tab> pumvisible() ? "\<C-n>" : "\<Tab>"
inoremap <expr> <S-Tab> pumvisible() ? "\<C-p>" : "\<S-Tab>"

" Use tab to trigger auto completion.  Default suggests completions as you type.
let g:completor_auto_trigger = 0
inoremap <expr> <Tab> Tab_Or_Complete()

@maralla what do you think of adding the above to the README? Seems more intuitive behavior.
