<p>The vim keybindings are enabled by
including <a href="../keymap/vim.js">keymap/vim.js</a> and setting
the <code>vimMode</code> option to <code>true</code>. This will also
automatically change 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, partial support for 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>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>
