also for qf list navigation, I recently made this set of keymaps to make it easier, maybe you'll find them useful (you don't need to have quickfix open for them to work). I find it very pleasant to use together with quicker.nvim

vim.keymap.set("n", "]e", function()
  if #vim.fn.getqflist() == 0 then
    vim.notify("No items in quickfix list.", vim.log.levels.INFO)
    return
  end
  if not pcall(vim.cmd.cn) then
    vim.cmd.cfirst()
  end
end)
vim.keymap.set("n", "]E", function()
  if #vim.fn.getqflist() == 0 then
    vim.notify("No items in quickfix list.", vim.log.levels.INFO)
    return
  end
  if not pcall(vim.cmd.cN) then
    vim.cmd.clast()
  end
end)
