[ and ] needed a reach/shift on most layouts and felt awkward next to the otherwise all-unshifted control scheme (hjkl, space, digits). , and . are adjacent, unshifted, easy to hit without looking away from the canvas -- a natural prev/next pair. Old bindings kept as a fallback rather than removed. Verified both in isolation (Update() with a KeyMsg) and live over a real SSH session -- the status-line ink swatch visibly cycles from █ to ▓ on a fresh connection. An initial live test after the rebind appeared to fail, but that traced to a stale session left over from the server restart, not an actual bug -- confirmed working correctly on a fresh connection.
