As I said before, there are only what... a few hundred trigger listings? Combine, compare, use... and you get everything.
Also, if ur looking for a map where a unit jumps, you should search the forums, or the trigger repository (that's how you spell it right?). I remember downloading a jumptest map there but I'm too lazy to post it (if you want it just say so).
You'll have to do a little more work than that; if you set the unit to be flying, they'll "fly" over units no matter what their animation height is. Meaning that jumping will be irrelevant; you can just gracelessly plow through ground targets.
Consider a morph ability, like the Druid of the Talon, and a few seconds after your unit transforms, order them to transform back.
