Emacs bindings demo

The emacs keybindings are enabled by including keymap/emacs.js and setting the keyMap option to "emacs". Because CodeMirror's internal API is quite different from Emacs, they are only a loose approximation of actual emacs bindings, though.

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.
