+<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>
