How to exactly unbind key mapping

[urayoru113]

In my .vimrc and lua setting

I've mapped nnoremap <tab> gt in .vimrc , then I configure lua setting as below

mappings = {
  list = {
      { key = "<tab>", action = "" }
  },
}

When the cursor in tab NvimTree_{i}, key tab will be hijacked, so I couldn't press tab to go to the next tab page.

How can I solve this problem?

"<tab" is missing the closing >

Sorry, I've edit it.
This is not the reason why <tab> key no function

You will need to use a capital T. See my config that also unbinds tab: nvim-tree.lua

This will be fixed via #1579 however I might put a quick fix in now. Thanks for letting me know!

Thanks. That works for me.

I didn't notice that because when I binded <tab> to other function such as { key = "<tab>", action = "tabnew" } in lowercase t, it will work with no problem.
