+<p><strong style="color: #c33; text-decoration: none">Note:</strong> The CodeMirror vim bindings do not have an
+active maintainer. That means that if you report bugs in it, they are
+likely to go unanswered. It also means that if you want to help, you
+are very welcome to look
+at <a href="https://github.com/codemirror/codemirror/issues?q=is%3Aissue+is%3Aopen+label%3Avim">the
+open issues</a> and see which ones you can solve.</p>

+int getchar(void)
+{
+  static char buf[BUFSIZ];
+  static char *bufp = buf;
+  static int n = 0;
+  if (n == 0) {  /* buffer is empty */
+    n = read(0, buf, sizeof buf);

+
+<p>The vim keybindings are enabled by including <code><a
+href="../keymap/vim.js">keymap/vim.js</a></code> and setting the
+<code>keyMap</code> option to <code>vim</code>.</p>
+
+<p><strong>Features</strong></p>
+
+<ul>
+  <li>All common motions and operators, including text objects</li>
+  <li>Operator motion orthogonality</li>
+  <li>Visual mode - characterwise, linewise, blockwise</li>
+  <li>Full macro support (q, @)</li>
+  <li>Incremental highlighted search (/, ?, #, *, g#, g*)</li>
+  <li>Search/replace with confirm (:substitute, :%s)</li>
+  <li>Search history</li>
+  <li>Jump lists (Ctrl-o, Ctrl-i)</li>
+  <li>Key/command mapping with API (:map, :nmap, :vmap)</li>
+  <li>Sort (:sort)</li>
+  <li>Marks (`, ')</li>
+  <li>:global</li>
+  <li>Insert mode behaves identical to base CodeMirror</li>
+  <li>Cross-buffer yank/paste</li>
+</ul>
+
+<p>For the full list of key mappings and Ex commands, refer to the
+<code>defaultKeymap</code> and <code>defaultExCommandMap</code> at the
+top of <code><a href="../keymap/vim.js">keymap/vim.js</a></code>.
+
+<p>Note that while the vim mode tries to emulate the most useful
+features of vim as faithfully as possible, it does not strive to
+become a complete vim implementation</p>
