xah-fly-keys is a efficient keybinding for emacs. (more efficient than vim)

It is a modal mode like vi, but key choices are based on statistics of command call frequency.

--------------------------------------------------
MANUAL INSTALL

put the file xah-fly-keys.el in ~/.emacs.d/lisp/
create the dir if doesn't exist.

put the following in your emacs init file:

(add-to-list 'load-path "~/.emacs.d/lisp/")
(require 'xah-fly-keys)
(xah-fly-keys-set-layout "qwerty") ; required

possible layout values:

adnw

HOW TO USE

M-x xah-fly-keys to toggle the mode on/off.

Important command/insert mode switch keys:

xah-fly-command-mode-activate (press 【<home>】 or 【F8】 or 【Alt+Space】 or 【menu】)

xah-fly-insert-mode-activate  (when in command mode, press qwerty letter key f. (Dvorak key u))

When in command mode:
【f】 (or Dvorak 【u】) activates insertion mode.
【Space】 is a leader key. For example, 【SPACE r】 (Dvorak 【SPACE p】) calls query-replace. Press 【SPACE C-h】 to see the full list.
【Space Space】 also activates insertion mode.
【Space Enter】 calls execute-extended-command or alternative.
【a】 calls execute-extended-command or alternative.

The leader key sequence basically replace ALL emacs commands that starts with C-x key.

When using xah-fly-keys, you don't need to press Control or Meta, with the following exceptions:

C-c for major mode commands.
C-g for cancel.
C-q for quoted-insert.
C-h for getting a list of keys following a prefix/leader key.

Leader key

You NEVER need to press Ctrl+x

Any emacs command that has a keybinding starting with C-x, has also a key sequence binding in xah-fly-keys. For example,
【C-x b】 switch-to-buffer is 【SPACE f】 (Dvorak 【SPACE u】)
【C-x C-f】 find-file is 【SPACE i e】 (Dvorak 【SPACE c .】)
【C-x n n】 narrow-to-region is 【SPACE l l】 (Dvorak 【SPACE n n】)
The first key we call it leader key. In the above examples, the SPACE is the leader key.

When in command mode, the 【SPACE】 is a leader key.

the following standard keys with Control are supported:

 ;; 【Ctrl+tab】 'xah-next-user-buffer
 ;; 【Ctrl+shift+tab】 'xah-previous-user-buffer
 ;; 【Ctrl+v】 paste
 ;; 【Ctrl+w】 close
 ;; 【Ctrl+z】 undo
 ;; 【Ctrl+n】 new
 ;; 【Ctrl+o】 open
 ;; 【Ctrl+s】 save
 ;; 【Ctrl+shift+s】 save as
 ;; 【Ctrl+shift+t】 open last closed
 ;; 【Ctrl++】 'text-scale-increase
 ;; 【Ctrl+-】 'text-scale-decrease

To disable both Control and Meta shortcut keys, add the following lines to you init.el before (require 'xah-fly-keys):
(setq xah-fly-use-control-key nil)
(setq xah-fly-use-meta-key nil)

I highly recommend setting 【capslock】 to send 【Home】. So that it acts as `xah-fly-command-mode-activate'.
