Recently Adobe released the essential graphics panel. In the demo they have sliders that can cycle through background options or different text layouts. I assume that it is some sort of expression that changes the Main Comps focus of a pre-comp as a background, but I am not sure how to write that expression. I have searched to no avail.
Does anyone know how to set this kind of slider control up?
This is perfect! Great explanation and does what I need. Thank you!
