Me too! I always use it around the barn, with in-hand work, longeing and under saddle work. I think giving treats from the saddle while at the same time encouraging a correct neck flexion is invaluable, as well as doing it that way on the ground.
I also use it when I'm grooming them, or asking for a pelvic tuck, or a back raise, so that they know that I'm not just doing those things to annoy them! Bridling, haltering, backing up when I go in to feed, moving away from me if I'm leading them, staying back, whatever. I don't use it all the time, just as reinforcement after I've taught the new behavior to them.
When longeing, I click when I get the right posture, regardless of gait. It's lovely to see them come to a screeching halt when they hear the click! I'll give a second click if they drop their pelvis to do so!
I use it when the vet, bodyworker, farrier, etc., are working on them and they do what we ask. I find it especially useful when they relax, lick and chew when working through a tension problem, either physical or mental. VERY useful!
