```
io.github.libtmux.Window.Window.rename(name: String) -> Window
```

Renames this window and returns a handle on it as it is now.

<p>A {@code :} or {@code .} is kept as written on every supported release but 3.7, which
refuses the name. A kept delimiter cannot then address the window, since a target splits on
both. Unlike a session name, a window name is never rewritten.
