  <p>The emacs keybindings are enabled by
  including <a href="../keymap/emacs.js">keymap/emacs.js</a> and setting
  the <code>keyMap</code> option to <code>"emacs"</code>. Because
  CodeMirror's internal API is quite different from Emacs, they are only
  a loose approximation of actual emacs bindings, though.</p>
  
  <p>Also note that a lot of browsers disallow certain keys from being
  captured. For example, Chrome blocks both Ctrl-W and Ctrl-N, with the
  result that idiomatic use of Emacs keys will constantly close your tab
  or open a new window.</p>
