How do you unbind a key?

[unrealapex]

I am trying to bind - to toggle NvimTree but it does not work as - is binded to go up a directory. How can I unbind this? I have tried this but it does not work:

require("nvim-tree").setup({
  sort_by = "case_sensitive",
  view = {
    adaptive_size = true,
    mappings = {
      list = {
        { key = "u", action = "dir_up" },
-- unbind -
        { key = "-", action = "" },
      },
    },
  },
  renderer = {
    group_empty = true,
  },
  filters = {
    dotfiles = true,
  },
})

Try setting it to nil.

Unfortunately that did not work.

That exact unmap is working for me. We even have the same u binding...

Perhaps there is an issue around configuration setup.

Please:

• try my config
• enable diagnostic logging for config: :help nvim-tree.log

    log = {
      enable = true,
      truncate = true,
      types = {
        config = true,

I realized what I did wrong. I tried binding - before I unset it from NvimTree.
code before:

local bufopts = { noremap=true, silent=true, buffer=bufnr }
-- trying to set the keymap before preventing NvimTree from overriding
vim.keymap.set('n', '-', ':NvimTreeToggle<CR>', bufopts)

        { key = "-", action = nil },

after:

        { key = "-", action = nil },

local bufopts = { noremap=true, silent=true, buffer=bufnr }
-- setting the keymap after preventing NvimTree from overriding it
vim.keymap.set('n', '-', ':NvimTreeToggle<CR>', bufopts)
