Macro Keyframe Editing

I've created a macro for a glitch effect using Prism Blur, Displace, Camera Shake and Duplicate. I don't want to keep dragging in .settings files and trying to search for the parts to edit and would prefer to be able to just use a macro. However when I created a macro (and recreated several times), I couldn't find a place to edit the keyframe timing. Maybe I'm just blind. I would appreciate any suggestions.
