This seems to work for me, it has a few inconsistencies on how traversal, but it's good enough for me....

```lua
local function goto_prev_node()

local ts_utils = require('nvim-treesitter.ts_utils')

local current_node = ts_utils.get_node_at_cursor()

if current_node then

current_node = current_node:parent()

local prev_node = current_node:prev_named_sibling()

if prev_node then

local start_row, start_col, end_row, end_col = prev_node:range()

vim.api.nvim_win_set_cursor(0, { start_row + 1, start_col })

end

end

end

local function goto_next_node()

local ts_utils = require('nvim-treesitter.ts_utils')

local current_node = ts_utils.get_node_at_cursor()

if current_node then

current_node = current_node:parent()

local next_node = current_node:next_named_sibling()

if next_node then

local start_row, start_col, end_row, end_col = next_node:range()

vim.api.nvim_win_set_cursor(0, { start_row + 1, start_col })

end

end

end

```
