"Is the milk hot?"
Depends on your platform. If you are using a Mac or PC, you should be able to add a Hebrew keyboard in the settings. Mac offers a keyboard called "Hebrew - QWERTY" which maps the keys phonetically to match a regular QWERTY keyboard. If you are using iPhone, you should be able to add a Hebrew keyboard in the keyboard settings. On Android I would recommend downloading Google Keyboard. You should be able to select Hebrew in the app settings.
Your comment has been of great service to me. I can't thank you enough. My Samsung Galaxy was replaced to a Samsung J3 Prime. It was not supporting fully the Hebrew Alphabet but with your suggestion. It can support for me 4 languages easily! Now, just by touching the icon of the world, I can switch so easily between English, German, Spanish and Hebrew. I suspect I could even add more. But this is sufficient and brillant! A lingot is coming your way from me. Thank you so much!
