|
| <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> |
