For the shortcut keys of the input method, another alternative is to
disable the fcitx input method, and use emaca oriented/tailed internal
input method, say, this one,
<https://github.com/DogLooksGood/emacs-rime>, when working within
emacs>. But I don't know to disable/overwrite the external application
invocation with the one defined by Emacs itself, when click on the
corresponding key sequence from within Emacs.
