my setting

function! s:check_back_space() abort "{{{
  let col = col('.') - 1
  return !col || getline('.')[col - 1]  =~ '\s'
endfunction"}}}
inoremap <silent><expr> <TAB>
      \ pumvisible() ? "\<C-n>" :
      \ <SID>check_back_space() ? "\<TAB>" :
      \ deoplete#manual_complete()

It should be a simple option...

Some plugin defines the mapping. But the auto completion plugin should not define it.
Because, the best mapping depends on users configuration.

And deoplete is not plugin for beginners.

Thanks for the snippets. I have tried both and both work but only after re-sourceing my .vimrc. I'm not sure why this is necessary. I do not map Tab for insert mode anywhere else in my settings.
