Use your chest and one of your legs whenever you feel a good tricking jump is coming. (360 spin flip)
Always communicate with your hands, but most of the time, LEGS.
Start with a run of realism, keep running until your momentum is out, then try to find a way to find a trick that is stored with more momentum in that run to repeat it again and again.
Remember that it's ok to do spar starters, those count as tricking too !
