On Windows's Japanese IME, when typing Hiragana, I can change the conversion mode to "No conversion", and then the romaji I type are entered as hiragana without having to press space or enter. Is there any way to do this on macOS (particularly High Sierra)?
For example, on Windows (with this setting), I can type "ひらが" into my search engine of choice and press enter to get the search. But on macOS, I have to press enter twice (once to accept the hiragana without conversion, and once to search).
Some kind of work-around would also be of interest. I type a lot of pure-hiragana when studying.
