Add the content of the keymap.cson file (or store the file) in ~/.atom to get Emacs key bindings in
Atom editor (http://atom.io).
Note: If you want a emacs-like file finder (when using 'ctrl-x ctrl-f') then install the Advanced-open-file package. Then change the 'ctrl-x ctrl-f' command in keymap.cson to 'advanced-open-file:toggle'
