In an earlier posting, it was noted that the keyboard shortcut Ctrl-Shift-V was needed to paste text into a terminal window rather than the simpler Ctrl-V. It didn’t occur to me at the time that there might be a similar shortcut for copying text from a terminal window. However, I came across a recent posting indicating that such an action may be conducted by using – you guessed it – Ctrl-Shift-C.
The same posting indicates the reason why the keyboard shortcut Ctrl-C cannot be used for this purpose – “Ctrl + C is already assigned to another command, which is the one that interrupts the program that is running in the terminal.”
