<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>
<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>Insert mode behaves identical to base CodeMirror</li>
<li>Cross-buffer yank/paste</li>
<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>
