I'm familiar with frame by frame animation, and the basic concepts of the frame editor. My question is specifically aimed towards the 'Advanced Frame Editor'. Animation in the regular frame editor is pretty straight forward. Specifically, how does the 'animation' button work in the advanced frame editor. you click on the animation icon and then highlight some points and it starts to 'shimmer'. Obviously, there is some function for this, but I can't seem to figure it out. There's no documenatation on this feature, yet I'm sure there are some 'advanced' techniques that can be useful to me.
