## Rex

Run the public and management servers:

```console
uv run rex server
```

Open the terminal management interface in another shell:

```console
uv run rex manage
```

The manager connects to `http://127.0.0.1:8001` by default. Use
`uv run rex manage --url http://host:port` to connect elsewhere. The footer
shows all controls: `H/L` switch tabs, `h/j/k/l` move, `y` copies the selected
value, `n` creates a key or device, `a` adds an action, `d` deletes the
selection, `r` refreshes, and `q` quits.
