Maybe I'm blind, but I've looked at the Minify settings tab over and over, high and low, and CANNOT find a "Help" button that does this.
The only "Help" button I see is the one in the top right corner with questions and answers.
How do I find the JS and CSS to optimize (minify) them with this plugin?
Use the "Help" button available on the Minify settings tab. Once open, the tool will look for and populate the CSS and JS files used in each template of the site for the active theme."
