Re: Emacs completion matches selection UI

João, Thanks for the detailed reply.  Our replies to Stefan crossed each other.

Anyway, the other 30% are probably legitimate cases where the user that
activated both yas-minor-mode and auto-complete-mode in a buffer
probably wants something like the following to happen:

   1. Press TAB

   2. If theres an active snippet key preceding point, expand it and
      leave

   3. Else attempt autocompletion at point, bring up a menu, whatever it
      does

   4. Else do whatever TAB is bound to

I wrote "probably" because I don't think I ever got a precise
description that clarified the desired interaction. That is, maybe some
users want 2 and 3 reversed.

Yes, that (yasnippet ahead of autocomplete) is what I have attempted to configure for myself.  To ensure 3 remains accessible I try to give my snippets names with low likelihoods for collision.

Again, thanks for the long authoritative reply.  My take away is that configuring multiple packages to trigger in some meaningful, predictable manner from a single event is currently part of the "dark arts", not something newbies should attempt.  It would be wonderful if some structure and formalism could be brought to this area.
