On WPN, all of SAT hotkeys require a fast mousemove, click and mousemove back to where it was. This is the most reliable for that site.
So you should be seeing the cursor move to the Fold button, click the Fold button, and then move back.
If this isn't working, then other things could be going wrong. I'd first suggest you try setting up a Fold hotkey with a keyboard letter, and see if that works. And also confirm that SAT is correctly detecting when Action is Required by using the menu item for Help -> Show Testing Info. It should change from NO to YES when its your turn
