This is a quick one. When you have a 4 page script like the one I'm working on right now, you need a way to quickly see if you've referenced a variable or not.
The reason I needed this is that I discovered I was using $_JobID and $_Job_ID in different places in my large script. I went around and standardized on $_Job_ID and wanted to delete my set variable for $_JobID. That's when I needed the find in script feature to make sure I had eliminated all references to $_JobID first.
Here's how:
Print your script except don't print just save it as a PDF. Now search inside your PDF to your heart's content!
