UKUI - can't find applications screen

I was told I could get to the Applications Screen with the Superkey, but nothing happens. I was getting the long list of applications from the Menu key, but went looking for a hotkey to get to Applications... and whatever I pushed looking for it, I think I turned off the Menus.

I'm using UKUI on ArcoLinux on a T540p Lenovo Thinkpad. I downloaded the Nvidia version due to the dual Intel/Nvidia nature of this machine.

I tried to get into the ArcoLinux forum off their website, but they have a Captcha that either I can't read very well, or at least they didn't like my responses.
