Is your feature request related to a problem? Please describe.

I want to rebind Select (split) and Select (vsplit).

Describe the solution you'd like

require("oil").setup({
  ...,
  keymaps = {
    ["g?"] = "actions.show_help",
    ["<CR>"] = "actions.select",
    ["<C-s>"] = { "actions.select", opts = { vertical = true }, desc = "..." },
    ...
  },
  ...
})

Something similar to oil.nvim.

Describe alternatives you've considered

None.
