Left/Right now adjust the highlighted value one step along the
OFF ← DEFAULT → ON scale, clamped at the ends (no wrap), complementing
Space which cycles through all states and wraps. Right steps toward ON,
Left toward OFF.
Extract the set/erase side-effect into __config_toggle_apply so Space,
Left, and Right share one implementation of the scope-aware
set -U/-g/-Ue/-eg logic. Update the in-panel keybind hint (now
width-padded via string pad so the border stays aligned) and the help
text and offline docs to cover the new keys.
