title: Karabiner-Elements how to map pc style home-end keys
body: <p>recently I'v updated to macOS sierra and found that Karabiner is not supported.
  Developers have released Karabiner-Elements but it seem in a "pre-user friendly" state. I cant understand how to map home and end keys in a pc style, as in the original Karabiner. 
  A user guide will be appreciated. </p>
