What is "jog-trotted"

Usage examples of "jog-trotted".

We had no trouble in seeing where we were going, no fear of falling into an open lead or of crippling ourselves against some unexpected obstacle, for with our useless goggles removed and powerful flashlight beams dancing erratically ahead of us as we jog-trotted along, visibility was seldom less than five yards, more often nearer ten.
