If you type things in Japanese, you have quite likely come across the problem of switching between Hiragana (ひらがな) and Katakana (カタカナ).
You can switch between Hiragana and Katakana by holding down Shift while typing.
As an example, typing in わたしはヘススです。requires Hiragana, Katakana, and Hiragana again. The quickest way to write this sentence starting from the US English Keyboard would be as follows (assuming you enabled the Command-Space Bar switching method:
- Press Command-Space Bar.
- Type the following keys: “watashiha “.
- Hold down the Shift key to switch to Katakana, then type “HESUSU “.
- Let go of Shift to switch back to Hiragana, and type “desu.”
