51 <p>The emacs keybindings are enabled by | |
52 including <a href="../keymap/emacs.js">keymap/emacs.js</a> and setting | |
53 the <code>keyMap</code> option to <code>"emacs"</code>. Because | |
54 CodeMirror's internal API is quite different from Emacs, they are only | |
55 a loose approximation of actual emacs bindings, though.</p> | |
56 | |
57 <p>Also note that a lot of browsers disallow certain keys from being | |
58 captured. For example, Chrome blocks both Ctrl-W and Ctrl-N, with the | |
59 result that idiomatic use of Emacs keys will constantly close your tab | |
60 or open a new window.</p> | |
