How can I type in half-width number in Japanese Kana keyboard? I want to type in numbers on Japanese Kana input keyboard, but it needs alt key to type in numbers. For example, to type in 3, you must type in Alt + 3.

However, this 3 is full-width, and it even does not go into the conversion list mode. So I found that it is not possible to type in the numbers in half-width.

Is this possible in Japanese Kana keyboard?
This Apple doc says you should uncheck the box for Full Width numbers in the Japanese keyboard Preferences.



However this does not seem to work with Kana input (presumably a bug).  As a workaround, you can use the Convert Text to Half Width service (turned on in system preferences/keyboard/shortcuts/services).
