How to autocomplete from dictionary while typing?

Question

I've set a dictionary with the command:

set dictionary+=~/Dictionary.txt

And add the following command to make more quickly to access it:

set complete+=k

But I still have to press <CTRL-N> to access it.

Is there a way to get the completions as I'm typing? I mean, without having to press any keys to access it. I would like to have it the same way the autocompletion works for words that are in the buffer, they appear in the autocompletion box as I type, without having to press any keys to invoke it.

Answer 1

I would suggest starting by defining an autocommand. One of these events seem promising to trigger what you need

InsertCharPre   when a character was typed in Insert mode, before inserting it
TextChangedI    after a change was made to the text in Insert mode when popup menu is not visible

An autocommand trigged by this event can be a function that triggers auto-completion. It's likely that you want this function to return early unless a minimum number of characters have been typed.
