Chaps!
I think this question is refering to what is know as a "leg aid". It's not so much a kick as leg pressure to direct the horse to what the rider wants him to do. Well trained horses should always understand leg pressure which can be heels, calves, thighs or butt (seat in horse talk).
You must always get on and off from the left side. Why? Hundreds of year ago horses were used during wars. And in those wars sword was the main weapon. A man's sword hung down his left leg, making it easier for him to pull it out quickly with his right hand. Because the sword's position was on the left, it was easier for the rider to throw his right leg across the horse's back. This prevented the sword from interfering with the rider's leg as he mounted on the horse. And so the riders started riding a horse from the left side. Even though horse riders today donot have swords, the custom has lasted through the years. And when horses are trained, they are trained to accept riders mounting from the left. So, today a rider mounting from the right could startle the horse.
the main one is that the riders back is parallel with the horse neck. the lower leg should stay beside the girth.
It means that, when it comes time to mount, riders will place their left foot in the left stirrup of the saddle and swing their right leg over the horse to place it in the right stirrup.
When you are riding a horse at a trot you can either sit the trot (something that require a lot of practice to be able to do well), or do a rising trot where you post (go up and down in the saddle) in time with the horse's outside leg.
The sole purpose of spurs is to act as a leg aid. For riders that have weak legs or horses that tend to be 'dead sided', spurs are a great way to communicate to your horse. Spurs in the wrong hands, however, can do great damage to the horse. Sharp edged spurs should never be used. Small, smooth spurs are all that is needed as an extension of the riders legs and heels.
The term to command a horse to turn right is Gee. To turn left it is Haw.
Typically, riders mount and dismount horses from the left side. This tradition dates back to when knights carried weapons on their left side, making it easier to swing their right leg over the horse. However, some riders may also mount from the right side for various reasons.

If a horse has hurt his/her leg the horse will be called lame till the leg has healed . If the horses leg is very badly hurt it may have to be put down (die) . But if it is just a minor injury you should keep the horse in his/her stable he/she stops limping.
