```
LibTmux.TmuxKeys.UnbindAsync(request: UnbindKeyRequest, cancellationToken: CancellationToken) -> Task
```

Removes a binding, or every binding in a table.

Removing a binding nobody made is not an error: tmux treats the
absence as the state that was asked for.

## Parameters

- `request` (UnbindKeyRequest): Which key, or every key in a table.
- `cancellationToken` (CancellationToken): Cancels the tmux command.

## Returns

A task that completes once the binding is gone.

## Raises

- `ArgumentNullException`: <paramref name="request" /> is null.
- `ArgumentException`: The request names no key and does not ask for all.
