How to disable picker's default keymap?

[ZhiyuanLck]

I want to use <C-U> to clear the input line in insert mode, but currently it has been mapped to list_scroll_up.

I tried to override the mapping with the following code, aiming to restore the original behavior. However, it seems to result in infinite recursion:

local function recover_keys(keys, mode)
    return function()
        vim.fn.feedkeys(vim.api.nvim_replace_termcodes(keys, true, false, true), mode)
    end
end

["<c-u>"] = {
    recover_keys("<c-u>", "i"),
    desc = "recover <C-U>",
    remap = false,
    mode = { "i" }
}

You can either disable the buffer-local keymap for both modes, which results in the default behavior:

picker = {
  win = {
    input = {
      keys = {
        ['<C-u>'] = false,

Or create an action to map different actions to each mode:

-- nvim -u repro.lua repro.lua
-- :lua Snacks.picker.files()
-- Type '12345'
-- <C-u>

-- repro.lua

vim.env.LAZY_STDPATH = '.repro'
load(vim.fn.system 'curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua')()

require('lazy.minit').repro {
  spec = {
    {
      'folke/snacks.nvim',
      opts = {
        picker = {
          actions = {
            smart_ctrl_u = function(picker)
              local mode = vim.fn.mode()
              if mode == 'i' then
                local key = vim.api.nvim_replace_termcodes('<C-u>', true, false, true)
                vim.api.nvim_feedkeys(key, 'n', false)
              end
              if mode == 'n' then
                picker:action 'list_scroll_up'
              end
            end,
          },
          win = {
            input = {
              keys = {
                ['<C-u>'] = { 'smart_ctrl_u', mode = { 'i', 'n' } },
              },
            },
          },
        },
      },
    },
  },
}

Actually, I realized that the real issue was passing the wrong mode to nvim_feedkeys, which led to the mapping being recursively triggered. Thanks for your answer!
