How do I change OCR data scraping parameters after I set up the wizard?

I eventually found 2 forum posts that covered changing the OCR engine. The jist of it is that it’s a GUI drag and drop replacement kind of thing. Still haven’t figured out how to change other parameters yet though. For example, the 1-digit value that I think controls sensitivity or whatever it’s called. Defaults to 3 IIRC.

Search engines and other forum posts keep pointing me to this page, Studio - Installing OCR Languages which is completely unrelated. I’m not sure why this keeps popping up.

I did grab a screenshot from that page though. The poorly circled settings are what I’d like to be able to change. I can’t get back to this GUI though. UIExplorer just shows some HTML tags.
