Merging animation tracks is a matter of finding a particular controller, making sure that controller is pinned or in the same desired area in both clips being merged, and using match options to combine the pieces into one continuous track.
Within this tool, one can also loop and scale animations in order to further edit data to extend cycles or manipulate timing. In the upper left of the story tool tab in the navigator, one can toggle between the looping and scaling options. When loop is selected, a track can simply be dragged by one end and extended into multiple. Depending on whether or not the track is a seamless cycle, the track can be cut into separate pieces through use of the razor tool, and additional merging can be done as necessary. In addition, with this option selected, an animation clip can also be reduced to a certain key frame, where timing will not be affected, and the animation will stop wherever the end of the clip is moved.
With the scaling option selected, an animation's length can be altered without losing any data. When the ends of the clips are moved, the animation's timing is altered to fit the new specified length. As previously stated, this is extremely useful for altering the timing of movements executed, to either make them faster or slower as per needed.
