The vim keybindings are enabled by including keymap/vim.js and setting the keyMap option to vim.

Features

• All common motions and operators, including text objects
• Operator motion orthogonality
• Visual mode - characterwise, linewise, blockwise
• Full macro support (q, @)
• Incremental highlighted search (/, ?, #, *, g#, g*)
• Search/replace with confirm (:substitute, :%s)
• Search history
• Jump lists (Ctrl-o, Ctrl-i)
• Key/command mapping with API (:map, :nmap, :vmap)
• Sort (:sort)
• Marks (`, ')
• :global
• Insert mode behaves identical to base CodeMirror
• Cross-buffer yank/paste

For the full list of key mappings and Ex commands, refer to the defaultKeymap and defaultExCommandMap at the top of keymap/vim.js.

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
