Hello, Thanks for your great Supertone Shift! I really enjoy it with only a single paid voice. I'd love to purchase and use more voices. I'm blind and use screen readers on Windows 11 like JAWS, NVDA, and Windows Narrator. Unfortunately, the GUI of Supertone Shift is not accessible and I've been having difficulty changing its settings. How can I switch to another voice with just a keyboard, without using a mouse? Can I tune settings like volume and pitch with a keyboard? I'd also appreciate it if Shift allowed me to configure using a text editor or Windows registry. I found the following file that seems like a configuration file, but it's in binary format. %APPDATA%\Supertone Shift\VoiceResource\.user_info
