I am failing to map Command+T, Command+[ and Command+] keys in Neovim under macOS / Alacritty.

I've reduced my Alacritty to be minimal:

  TERM: xterm-256color
  size: 16
  - {key: T,        mods: Command, chars: "\×80\xfc\x80t"}
  - {key: LBracket, mods: Command, chars: "\×80\xfc\×80["}
  - {key: Bracket,  mods: Command, chars: "\×80\xfc\×80]"}

And also Neovim's:

vim.kevmap.set('n', '<D-t>', vim.cmd.tabnew)
vim.keymap.set('n', '<D-[>', vim.cmd.tabprevious)
vim.keymap.set('n', '<D-]>', vim.cmd.tabnext)
  1. I went to nvim,

  2. entered the following command,

    echo "\<D-t>"
  3. got an output:

  4. used the output to add a binding in Alacritty:

    - { key: T, mods: Command, chars: "\x80\xfc\x80t" }

What am I doing wrong?

  • Does mapping ×80\xfc\x80t work? You can try using <C-v><C-t> to insert that direct sequence, but you can probably also use some escape sequence (I'm not that familiar with Neovim's lua stuff). Commented Jun 23, 2023 at 17:11

What I ended up doing was going to Neovim opening a new file and going into insert mode.

Then typing the key combo I was hoping to bind.

In this case Command + Shift + {. When I did this I was able to see what key Alacritty was sending to Neovim.


Then I was able to use this keybinding in my config.

vim.keymap.set("n", "<S-D-{>", "<cmd>bp<CR>", { silent = true })
vim.keymap.set("n", "<S-D-}>", "<cmd>bn<CR>", { silent = true })

I hope that helps!
