I like "Evaluate In Place," because it hides code and works well. However, I can't figure out how to return to the original code when I want to modify it. I'm sure there is an easy way, but I can't find it in the documentation. Here is the code. FileNames["Index.xls"] is in the PopupMenuBox function.
If I select the popup box and Ctrl-Shft-E I can see evaluated code with inside of Cell[long expression,"Input"], I cant really untangle it.
