Arcing Jump ALA Street Fighter Alex

I would recommend taking a look at "how I learned to stop worrying and love the expression editor" on the clickstore. It's got good, easy to follow, practical examples of this sort of thing: Please login to see this link..

Between the on-screen tutorial and the commented code, it seems relatively well explained to me.

I would break the movement down into its constituent parts. Ignore the arms and legs, as their animation is secondary, and look just at the torso.

On the X axis, the movement seems to be a simple ease-out movement (starts fast, ends slow). The Y axis movement can be split into two halves: (A) up to the apex, and (B) back down to the ground. (A) is an ease-out movement, while (B) is an ease-in movement (slow to start, fast to end). The Easings section should contain everything you need to recreate these components. Find equations that move appropriately (eg. Cubic In and Cubic Out) and apply the equations to your character as he has applied them to the orange ball in the demo.

There are some additional aspects to the animation in the GIF, like a little bit of anticipation at the start, and some rotation and cushioning at the end, but these would have been achieved within the drawings of the animation itself, not with how the object is moved by the engine.
