How do I know "which" SEO operation I want to remove?

I've got this mesh.
A while ago, I subtracted with upward extrusion the footing you see in the picture.
I want to "undo" (X) out that operation from the list. How can I find out "which" was that exact operation so I don't undo or "X" out another SEO operation I don't want undone....

Scroll thru the list, stopping long enough for the operator to be highlighted.
It may be easier to see in the 3D window (do a marque or cutting plane thru your section).

You can also do it the other way - select the Operator and see the list of elements it is operating on. It may be a shorter list (or at least have less meshes operated upon).

Also, if you have a unique ID for the footing, the ID should appear in the list of operations making it easier to pick out.
