tmux command: [`rename-window`](/en/tmux/latest/manual/rename-window/)

```
LibTmux.Window.RenameAsync(name: string, cancellationToken: CancellationToken) -> Task<Window>
```

Renames this window.

tmux expands the name as a format, so a <c>#</c> in it does not survive
verbatim.

## Parameters

- `name` (`string`): The new name.
- `cancellationToken` (`CancellationToken`): Cancels the tmux command.

## Returns

A replacement handle carrying the new name.
