Keyframes box not showing up to zoom in on image

[miafaulkner]

I am trying to zoom in on an image on Premiere using keyframes. However, the pink box that shows up next to the effect controls that allows you to add keyframes isn't appearing. This is probably very easy to fix but I'm relatively new, hope this makes sense!
