I am failing to map <kbd>Command+t</kbd>, <kbd>Command+[</kbd> and <kbd>Command+]</kbd> keys in neovim under macOS / Alacritty.

I've reduced my neovim/Alacritty to be minimal. Both configs in their entirety can be seen on the screenshot:

My thinking process for assigning the `chars` in alacrity was this:

1. I went to `nvim`,
2. entered the following command,

    ```
    echo "\<D-t>"
    ```

3. got an output:

    ```
    <80><fc><80>t
    ```

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

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

What am I doing wrong?
