emacs mode inside ipython(jupyter) notebook

Here's a github gist that you'll need to paste into

custom.js

which is located in

~/.ipython/profile_default/static/custom/custom.js

	// register a callback when the IPython.notebook instance is created.
	$([IPython.events]).on('app_initialized.NotebookApp', function(){
	function to(mode) {
	// this can be either 'vim' or 'emacs'
	var mode = mode || 'emacs';
	// first let's apply mode to all current cells
	function to_mode(c) { return c.code_mirror.setOption('keyMap', mode);};
	var cells = IPython.notebook.get_cells();
	if (cells != null) {
	cells.map(to_mode);
	}
	// apply the mode to future cells created
	IPython.Cell.options_default.cm_config.keyMap = mode;
	};
	require(["codemirror/keymap/emacs"],
	function (_) {
	if (IPython.notebook != undefined) {
	to('emacs');
	};
	});
	});
