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

"See help completion for source,
"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.
"Window users can copy the file to their machine.
function! Tab_Or_Complete()
  if col('.')>1 && strpart( getline('.'), col('.')-2, 3 ) =~ '^\w'
    return "\<C-N>"
    return "\<Tab>"
:inoremap <Tab> <C-R>=Tab_Or_Complete()<CR>
:set dictionary="/usr/dict/words"



Even easier than <Tab> is to have words completed automatically. There are some drawbacks to this, but the word_complete.vim plugin works pretty well.

To use the dictionary, add 'k' to your ':set complete'. For language keywords (tags), also add ']'. See :help 'complete'.
