For the Chinese input method, the input state(English or Chinese) can be
switched by the ‘shift' key on keyboard by pressing it and then releasing it
quickly(about in 200ms). It works well in all applications I tested
except Emacs.
In Emacs, if I press shift+Enter and then release it quickly(about
200ms), the state of the input method switches. This happens for the
following keys:
shift+Enter
shift+tab
shift+Backspace
shift+F[1~12]
And it doesn’t happen for ascii chars like a, b, c, d …
I talked to an author of an input method. And he guesses that Emacs
maybe processes some keyboard events and leave the keyup event of shift
to the input method. So it switches the state. This does’t happen for
other applications.
It’s on macOS 10.13.6.
In emacs with Chinese input method active,
