When the keyboard input status is ‘Korean’, there is a problem that the “cmd+shift+c” shortcut (url copy) is recognized as “shift+c”. In addition, it was confirmed that “cmd+shift+u” is also not properly recognized when the keyboard input status is ‘Korean’. Not all shortcuts are like that, but these two are for sure.
I attached the video, so please refer to it and revise it quickly.
