My Arch Linux machine has KDE Plasma desktop installed and I’m using Konsole as a terminal. In Konsole, when I highlight text and press Ctrl+Shift+C on my keyboard to copy it, I get this popup message.
The key sequence 'Ctrl+Shift+C' is ambiguous. Use 'Configure Shortcuts' from the 'Settings' menu to solve the ambiguity. No action will be triggered.
The Konsole version is v20.08.0-1.
UPDATE: This only occurs in a a terminal I open in a Dolphin folder. When I open a Konsole terminal alone, Ctrl+Shift+C copies correctly.
