32 <h2>Vim bindings demo</h2>
33
34 <p><strong style="color: #c33; text-decoration: none">Note:</strong>
35 The CodeMirror vim bindings are maintained in
36 the <a href="https://github.com/replit/codemirror-vim">codemirror-vim</a>
37 repository, not this project. The file is still included in the
38 distribution for backwards compatibility.</p>

57
58 <p>The vim keybindings are enabled by including <code><a
59 href="../keymap/vim.js">keymap/vim.js</a></code> and setting the
60 <code>keyMap</code> option to <code>vim</code>.</p>
61
62 <p><strong>Features</strong></p>
63
64 <ul>
65 <li>All common motions and operators, including text objects</li>
66 <li>Operator motion orthogonality</li>
67 <li>Visual mode - characterwise, linewise, blockwise</li>
68 <li>Full macro support (q, @)</li>
69 <li>Incremental highlighted search (/, ?, #, *, g#, g*)</li>
70 <li>Search/replace with confirm (:substitute, :%s)</li>
71 <li>Search history</li>
72 <li>Jump lists (Ctrl-o, Ctrl-i)</li>
73 <li>Key/command mapping with API (:map, :nmap, :vmap)</li>
74 <li>Sort (:sort)</li>
75 <li>Marks (`, ')</li>
76 <li>:global</li>
77 <li>Insert mode behaves identical to base CodeMirror</li>
78 <li>Cross-buffer yank/paste</li>
79 </ul>
80
81 <p>For the full list of key mappings and Ex commands, refer to the
82 <code>defaultKeymap</code> and <code>defaultExCommandMap</code> at the
83 top of <code><a href="../keymap/vim.js">keymap/vim.js</a></code>.
84
85 <p>Note that while the vim mode tries to emulate the most useful
86 features of vim as faithfully as possible, it does not strive to
87 become a complete vim implementation</p>
