<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>
