I thought that the manual suggests that there is an icon on the object in the time line that reveals the curve and allows one to edit it. I don't see that "icon" to edit the curve.

Okay, what I'd like to do it be able to zoom on a portion of a jpg/image but I want to pause at the beginning for a second or so at the actual size, then zoom and then hold the full zoom at the end for another second or so. I believe that I accomplished it and may have even saved it. BUT it clearly saved the zoom position on that particular image. So, applied to another image, it zooms the "wrong" area. Fine - I was then hoping to edit or move the "zoom" position on this second image. I thought that I could then edit the curve and move that position. Or do I have to play with keyframe markers for each image separately. Or if anyone understands what I'm trying to accomplish - a suggestion of another way is fine.
