FakeVim Modes and Commands

In the FakeVim mode, most keystrokes in the main editor are intercepted and interpreted in a way that resembles Vim. Most of the supported commands can be followed by a motion command or executed in visual mode, or they work with registers, or can be prefixed with a number of repetitions.

The following sections describe the commands emulated in the supported modes and how they diverge from Vim in functionality:

• Normal
• Visual
• Command line (:)
• Insert and replace

For more information about using Vim, see Documentation on the Vim web site.

Normal and Visual Modes

• Basic movement, such as h/j/k/l, <C-U>, <C-D>, <C-F>, <C-B>, gg, G, 0, ^, $
• Word movement, such as w, e, b
• Inner/a movement, such as ciw, 3daw, ya{
• f and t movement
• [ and \c ] movement
• { and } paragraph movement
• Delete/change/yank/paste with register
• Undo and redo
• <C-A> and <C-X> increase or decrease a number in decimal, octal, or hexadecimal format (for example 128<C-A> on or before "0x0ff" changes it to "0x17f")
• . repeats the last change
• /search, ?search, *, #, n, N - most of regular expression syntax is used in Vim except that \< and \> are the same as \b in QRegExp
• @ and q (macro recording and execution) special keys are saved as <S-Left>
• Marks
• gv goes to last visual selection; can differ if text is edited around it
• Indentation using =, <<, >>, with movement, count, and in visual mode
• to upper/lower, such as ~, gU, gu
• i, a, o, I, A, and O enter insert mode
• Scroll window, such as zt, zb, zz
• Wrap line movement, such as gj, gk, g0, g^, g$

Command-Line Mode

• :map, :unmap, :inoremap, and so on
• :source sources vimrc files line-by-line
• :substitute substitutes an expression in a range
• :'<,'>!cmd filters through an external command (for example, sorts the lines in a file with :%!sort)
• :<range>sor[t][!]
• :.!cmd inserts the standard output of an external command
• :read
• :yank, :delete, :change
• :move, :join
• :20 goes to an address
• :history
• :registers, :display
• :nohlsearch
• :undo, :redo
• :normal
• :<, :>
• set formatoptions=, see :h fo-table in the Vim documentation. Currently supported letters: fo-j

Insert Mode

• <C-O> executes a single command and returns to insert mode
• <C-V> inserts a raw character
• <insert> toggles replace mode
