I upgraded to 21.04, then a message appear to set shortcut for changing languages (RO - EN). For some reason I set Left Shift + Left Ctrl.
Now I realized I can't open a new tab in terminal anymore (with Ctrl + Shift + T) because the language is changing instead.
I opened the Region & Language settings, then Input Sources: Keyboard Shortcuts. Here the message is: These keyboard shortcuts can be changed in the keyboard settings.
Ok, I opened the Keyboard Shortcuts and I have Typing: Switch to next input source: Super + Space.
But I can't see the Ctrl + Shift shortcut I want to remove. So, where can I fix this?
