Codex and Claude open their model catalogs directly, without provider or recents tabs. `↑/↓` select a model, `←/→` adjust its effort, `Enter` applies the model and any explicit effort draft, and `Esc` cancels.

 Short terminals keep the focused model and select/cancel actions visible, hiding descriptions and neighboring models first, then the effort row when only two rows remain.
 Shortcuts sit below the title and effort levels have their own section; DSH, Claude, and Codex use the terminal background while covering the text underneath.
