Select Hero_SkeletonData in the inspector. You will see Mix table.
Ex:
[Walk] [Jump] 0.2
When transition from "Walk" to "Jump" it will take 0.2 seconds. This is "Crossfading"
To play multiple animations ( or Mix them ) you can use skeletonAnimation.state.SetAnimation( trackNumber*, trackName, loop )
Track number is the important part.
Ex:
If Walk is playing in Track 0, you can play Shoot in Track 1 without interrupting Walk. Make sure that Shoot only animates the Arm and Gun; do not make keyframes for legs.
Finally (and most advanced / confusing for most) is the skeleton.Mix function which lets you blend (per frame) to another animation. This enables you to do whatever you want in terms of blending animations (like Blend Trees in Mecanim)
