Picker custom function on keymap

[kocv59]

When I have selected something in the picker how can I set another keymap like C-w to do a custom function with the selection? Instead of the confirm action when I type Enter.

Tip

To apply win styles to all pickers use opts.picker.win.

opts = {
  picker = {
    sources = {
      files = { -- NOTE: `files` picker
        actions = {
          print_selected = function(picker, item)
            local multi_selection = picker:selected { fallback = true }
            vim.print { item, multi_selection }
          end,
        },
        win = {
          -- NOTE: Using the `input` keymap with `mode = { 'i', 'n' }` will cover almost all cases,
          -- so you can skip creating `list` and `preview` keymaps
          input = {
            keys = {
              ['<CR>'] = { 'print_selected', mode = { 'i', 'n' } },
              -- Or
              ['<CR>'] = { { 'print_selected', 'confirm' }, mode = { 'i', 'n' } },
            },
          },
          -- NOTE: `explorer` picker is focused on the list by default
          list = {
            keys = {
            },
          },
          preview = {
            keys = {

Variant 2

Note

Jump is the default action but some pickers may override it. See sources.lua.

opts = {
  picker = {
    sources = {
      files = { -- NOTE: `files` picker
        confirm = function(picker, item, action) -- [[Override]]
          local multi_selection = picker:selected { fallback = true }
          vim.print { item, multi_selection }
          Snacks.picker.actions.jump(picker, item, action)
        end,

Or you can just configure it as a source:

{
  'folke/snacks.nvim',
  priority = 1000,
  lazy = false,
  ---@module 'snacks'
  ---@type snacks.Config
  opts = {
    picker = {
      sources = {
        <source> = { -- Can be a custom name
          -- finder = ...,
          -- format = ...,
          -- preview = ...,
          win = {

I tried this but nothing happens can you see a problem?

Snacks.picker.pick({
  finder = finder,
  format = format,
  actions = {
    print_selected = function(picker, item)
      print("example")
    end
  },
  win = {
    input = {
      keys = {
        ["C-w"] = { "print_selected", mode = { "i", "n" } }
      }
    }
  }
})

["<C-w>"] instead of ["C-w"].

Thank you it's fixed. Can I put the function directly under keys or has to be a string that points to actions?

[drowning-cat]

It must be an action.
