|
|
|
37 repository, not this project. The file is still included in the

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>

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>
