```
tmux.Session.PreviousWindow(ctx: context.Context) -> (Window, error)
```

PreviousWindow makes the previous winlink current in the receiver session and returns that freshly materialized session-specific [Window]. The selection is session-scoped; it does not promise focus for clients attached to other sessions. A transport or context error can be delivery-ambiguous and no rollback is attempted. Command or refresh failure returns a zero Window.
