<C-e>, <C-y> keys for scroll in explorer?

[rudenkornk]

New snacks explorer does not have <C-e> <C-y> one-line scrolling out of the box.
Is it possible to set them up? I searched through the config but did not find keys for one-line scroll.

What do you want to scroll, and why are <C-e> and <C-y> used for that specifically?

opts = {
  picker = {
    sources = {
      explorer = {
        actions = {
          list_scroll_down_1 = function(picker)
            picker.list:scroll(1, false)
          end,
          list_scroll_up_1 = function(picker)
            picker.list:scroll(-1, false)
          end,
        },
        win = {
          input = {
            keys = {
              ['<C-x><C-y>'] = { 'list_scroll_down_1', mode = 'i' },
              ['<C-x><C-e>'] = { 'list_scroll_up_1', mode = 'i' },

Thanks for the snippet!

I want to scroll this area in red box

Your snippet works, but only if I enter the input box above. <C-d> and <C-u> keys work without entering this input box.
Is it possible to achieve same behaviour?

You can define a key for:

• input
• list
• preview

Like this:

win = {
  input = { -- list, preview
    keys = {
      ['<C-e>'] = 'list_scroll_down_1',                          -- normal mode
      ['<C-e>'] = { 'list_scroll_down_1', mode = 'i' },          -- insert mode
      ['<C-e>'] = { 'list_scroll_down_1', mode = { 'i', 'n' } }, -- insert or normal mode

---

opts = {
  picker = {
    sources = {
      explorer = {
        actions = {
          list_scroll_down_1 = function(picker)
            picker.list:scroll(1, false)
          end,
          list_scroll_up_1 = function(picker)
            picker.list:scroll(-1, false)
          end,
        },
        win = {
          input = {
            keys = {
              ['<C-x><C-e>'] = { 'list_scroll_down_1', mode = 'i' },
              ['<C-x><C-y>'] = { 'list_scroll_up_1', mode = 'i' },
              ['<C-e>'] = 'list_scroll_down_1',
              ['<C-y>'] = 'list_scroll_up_1',
            },
          },
          list = {
            keys = {
              ['<C-e>'] = 'list_scroll_down_1',
              ['<C-y>'] = 'list_scroll_up_1',

Thanks, this works!
Though to be aligned with usual vim keys, it should be smth like

    opts = {
      picker = {
        hidden = true,
        ignored = true,
        actions = {
          list_scroll_down_1 = function(picker)
            picker.list:scroll(1, false)
          end,
          list_scroll_up_1 = function(picker)
            picker.list:scroll(-1, false)
          end,
        },
        win = {
          input = {
            keys = {
              ["<C-y>"] = { "list_scroll_up_1", mode = { "n" } },
              ["<C-e>"] = { "list_scroll_down_1", mode = { "n" } },
            },
          },
          list = {
            keys = {
              ["<C-y>"] = { "list_scroll_up_1", mode = { "n" } },
              ["<C-e>"] = { "list_scroll_down_1", mode = { "n" } },
            },
          }
        },
      },
    },

Yep, you're right. I updated the comment.
