The author, JohnPalmieri, says:
- Lightning completion is an improvement on whatever completion emacs does already;
- it incorporates dynamic completion: completion without having to hit the TAB key
- or anything else. This is very useful when added to commands like find-file or
- switch-to-buffer or describe-lisp-function.
Lightning completion is available from http://www.math.washington.edu/~palmieri/Emacs/light.html.
It has not been updated recently (30 September 2005).
