These are related to the favor tool, which you can find in the graph by clicking the heart button. The favor tool is also known as "tween machine" and other names. It is convenient for a number of tasks, but specifically for creating in-between poses. Eg, you say you have two poses and you want to create a new pose between them. The favor tool can easily create a new pose which is closer to the previous or next pose. We'll have a video explaining how to use it soon!
