<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>
