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

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