Confirmed since Anthropic's documentation has since written up effortSlider:thisSessionOnly, on Customize keyboard shortcuts. | `effortSlider:thisSessionOnly` | s | Apply the focused [effort level](/docs/en/model-config#adjust-effort-level) to this session only. Requires v2.1.257 or later | keybindings see the edit
