`a` opens aesel pro here and `ar` opens the history, the way c and cr do for Claude and co and cor for Codex. `ac history` lists the sessions this machine has had — when, mode, model, directory, subject — and a number (or --last) reopens one: same directory, same engine, the old thread. On the status line the model is the one fact that is a control: it underlines under the mouse and a click opens the settings drawer, wherever the layout has put the line.
