```
unbind(Server, Key0, Options)
-spec unbind(tmux_server:t(),
             key(),
             #{table => binary()}) ->
                {ok, tmux_operation:completed()} |
                {error, tmux_operation:failure()}.
```

Remove one key from the explicit table, defaulting to prefix. Only table is accepted in the options map. A missing key in an existing table is a native no-op; a missing explicit table remains an error. Removing the final custom binding can remove its table, so a repeated call can then report that missing table. Invalid native key names are never quietly suppressed.

Performs I/O. Effects already queued by a client are unaffected. Use
`clear_table/2` to remove an entire explicitly named table.

## Parameters

- `Server` (`tmux_server:t()`)
