Jump is one of the basic moves used in all Tekken games.
It can be acomplished by jabing the anolog stick in the up-left, up or up-right position. In the original Tekken and Tekken 2, characters could jump unrealistically high. As of Tekken 3, jumping was made more realistic.
There are also moves that require jumping. It can also be used to dodge certain moves, if timed right.
