<p>The emacs keybindings are enabled byincluding <a href="../keymap/emacs.js">keymap/emacs.js</a> and settingthe <code>keyMap</code> option to <code>"emacs"</code>. BecauseCodeMirror's internal API is quite different from Emacs, they are onlya loose approximation of actual emacs bindings, though.</p>
<p>Also note that a lot of browsers disallow certain keys from beingcaptured. For example, Chrome blocks both Ctrl-W and Ctrl-N, with theresult that idiomatic use of Emacs keys will constantly close your tabor open a new window.</p>
<script> CodeMirror.commands.save = function() { var elt = editor.getWrapperElement(); elt.style.background = "#def"; setTimeout(function() { elt.style.background = ""; }, 300); }; var editor = CodeMirror.fromTextArea(document.getElementById("code"), { lineNumbers: true, mode: "text/x-csrc", matchBrackets: true, keyMap: "emacs" }); </script>
