I tried using MS-IME first and the recommended keystroke shortcuts (between Direct Input – katakana – hiragana – romaji) didn't work. ChatGPT recommended Google Input Editor so I'm trying that but have run into the same trouble. Further queried ChatGPT and it apparently is not up to speed with Microsoft's verbiage in Windows 10 Pro. I've played with what is offered to the point of frustration. Solutions other than using the mouse to toggle are most welcome!
