You can set your own shortcuts in Edit/Keyboard Shortcuts. Set Product Area to Type Menu and look for the Change Case commands or set Product Area to Panel Menus and look for Character: All Caps.

I have a similar issue: The EIP panel cannot be resized at all. So previewing small buttons and such is nearly impossible!
Im using CC 2018 (Swedish version) on Windows 10.
