Features

  • Map keys to perform configurable multi-step actions: if condition for step one is true - execute step one action, else check step two, and so on until falling back to executing original keys. This is usually referred to as “smart” keys (like “smart tab”). See :h MiniKeymap.map_multistep().

    There are many built-in steps targeted for Insert mode mappings of special keys like <Tab>, <S-Tab>, <CR>, and <BS>:

    • Navigate and accept built-in Insert mode completion. Useful for mini.completion.
    • Navigate and expand mini.snippets.
    • Execute <CR> and <BS> respecting mini.pairs.
    • Jump before/after current tree-sitter node.
    • Jump before opening and after closing characters (brackets and quotes).
    • Increase/decrease indent when cursor is inside of it.
    • Delete all whitespace to the left (“hungry backspace”).
    • Navigate built-in snippet engine (:h vim.snippet).
    • Navigate and accept in hrsh7th/nvim-cmp completion.
    • Navigate and accept in Saghen/blink.cmp completion.
    • Navigate and expand L3MON4D3/LuaSnip snippets.
    • Execute <CR> and <BS> respecting windwp/nvim-autopairs.

  • Map keys as “combo”: each key acts immediately plus execute extra action if all are typed within configurable delay between each other. See :h MiniKeymap.map_combo().

    Some of the common use cases include:

    • Map insertable keys (like “jk”, “kj”) in Insert and Command-line mode to exit into Normal mode.
    • Fight against bad habits of pressing the same navigation key by showing a notification if there are too many of them pressed in a row.

Quickstart

Multi-step

Setup that works well with ‘mini.completion’ and ‘mini.pairs’:

local map_multistep = require('mini.keymap').map_multistep

map_multistep('i', '<Tab>',   { 'pmenu_next' })
map_multistep('i', '<S-Tab>', { 'pmenu_prev' })
map_multistep('i', '<CR>',    { 'pmenu_accept', 'minipairs_cr' })
map_multistep('i', '<BS>',    { 'minipairs_bs' })

Combos

“Better escape” to Normal mode without having to reach for <Esc> key:

local map_combo = require('mini.keymap').map_combo

-- Support most common modes. This can also contain 't', but would
-- only mean to press `<Esc>` inside terminal.
local mode = { 'i', 'c', 'x', 's' }
map_combo(mode, 'jk', '<BS><BS><Esc>')

-- To not have to worry about the order of keys, also map "kj"
map_combo(mode, 'kj', '<BS><BS><Esc>')

-- Escape into Normal mode from Terminal mode
map_combo('t', 'jk', '<BS><BS><C-\\><C-n>')
map_combo('t', 'kj', '<BS><BS><C-\\><C-n>')

Show notification if there is too much movement by repeating same key:

local notify_many_keys = function(key)
  local lhs = string.rep(key, 5)
  local action = function() vim.notify('Too many ' .. key) end
  require('mini.keymap').map_combo({ 'n', 'x' }, lhs, action)
end
notify_many_keys('h')
notify_many_keys('j')
notify_many_keys('k')
notify_many_keys('l')

Installation

This plugin can be installed as part of ‘mini.nvim’ library (recommended) or as a standalone Git repository.

There are two branches to install from:

  • main (default, recommended) will have latest development version of plugin. All changes since last stable release should be perceived as being in beta testing phase (meaning they already passed alpha-testing and are moderately settled).
  • stable will be updated only upon releases with code tested during public beta-testing phase in main branch.

Here are code snippets for some common installation methods (use only one):

With mini.deps

  • ‘mini.nvim’ library:

    Branch Code snippet
    Main Follow recommended ‘mini.deps’ installation
    Stable Follow recommended ‘mini.deps’ installation

  • Standalone plugin:

    Branch Code snippet
    Main add(‘nvim-mini/mini.keymap’)
    Stable add({ source = ‘nvim-mini/mini.keymap’, checkout = ‘stable’ })
With folke/lazy.nvim

  • ‘mini.nvim’ library:

    Branch Code snippet
    Main { 'nvim-mini/mini.nvim', version = false },
    Stable { 'nvim-mini/mini.nvim', version = '*' },

  • Standalone plugin:

    Branch Code snippet
    Main { 'nvim-mini/mini.keymap', version = false },
    Stable { 'nvim-mini/mini.keymap', version = '*' },
With junegunn/vim-plug

  • ‘mini.nvim’ library:

    Branch Code snippet
    Main Plug 'nvim-mini/mini.nvim'
    Stable Plug 'nvim-mini/mini.nvim', { 'branch': 'stable' }

  • Standalone plugin:

    Branch Code snippet
    Main Plug 'nvim-mini/mini.keymap'
    Stable Plug 'nvim-mini/mini.keymap', { 'branch': 'stable' }

Important: no need to call require('mini.keymap').setup(), but it can be done to improve usability.

Note: if you are on Windows, there might be problems with too long file paths (like error: unable to create file <some file name>: Filename too long). Try doing one of the following:

  • Enable corresponding git global config value: git config --system core.longpaths true. Then try to reinstall.
  • Install plugin in other place with shorter path.

Default config

-- No need to copy this inside `setup()`. Will be used automatically.
