In order to type upper case in terminal, I have to hold caps_lock+shift together which is very upset. I have tried to change the keyboard layout in settings > region&language>input source,but it seems no one is suitable.
Well, I find...
The first time I log into the terminal(reload computer rather than close the terminal and open again), I can type lower case, if I hold the Shift key, then the case will turn upper.
If I press the CapsLock key, then the situation will turn around which means that I will type upper case without holding any keys and have to hold the Shift key in order to type lower case
There ever exited a situation that if i pressed Win+CapsLock, I could change the situation, but only one times.
