I've run in Japanese input mode for 6 years now. I generally had no issues. Now with OS X 10.10 (Yosemite) I can no longer type a backslash. This means in order to use the Terminal I have to completely get out of Japanese input and switch it US input where as before Yosemite if I was in Romanji mode things just worked.
How can I either (a) get it to work like it did before or (b) how do I type a backslash while in Japanese Input mode?
Note: Backslash is used in the Terminal and when programming very often. I can't imagine there isn't some way to fix this otherwise Japanese programmers would be up in arms.
