Emacs: Xah Fly Keys, Frequently Asked Questions
How does it compare to ergoemacs-mode?
ergoemacs-mode remaps the most frequently used emacs commands to use Alt+key, with key choice based on frequency of command call.
ergoemacs-mode is part of FSF GNU Emacs, in ELPA repository. (but you should probably download the version from MELPA, because it's usually more up-to-date.)
If you don't like modal ways, I recommend ergoemacs-mode.
