When you press "left Ctr + Left Shift" when typing, you will be swithed to Iran input. And there is no way to diable it!
I went to Preference > Keyboard > Layout, diabled Iran Keyboard layout, and went to "Layout Option" to disable the shortkey for switching Layouts, but I can't diable it!! After I diable it, it will be toggled back.
Because I need to use Emacs, and there are a lot of command that will conflict this "Ctr + Shift", it's really annoying!
Please help me to diable this Iran input and this shortkey for switching input.
