Power shifting is another term for it. Quick throttle control and timing are needed to get it right. It's easy once you get used to it and, if done properly, will not harm the tranny. This is exactly how air-shifters works, the only difference is that the ignition is 'killed' in between shifts to control the engine-to-gears timing.
I do it all the time. You should use no force at all to change gears, upshifting or downshifting.
Yep. It's just a quick twist, closing the throttle, shifting and twisting the throttle back into position. Wait a split second too long on closing, though and gear lever won't move. What kills the tranny is not getting the timing right and trying to force it into gear.
Practice at low speeds before you start trying it under heavier acceleration.
