Ctrl+C interrupts the currently running program in a UNIX terminal, usually resulting in the program dying. That's probably what the commenter was referring to.
except usually the interrupt has visible feedback, namely returning user back to prompt or a notice that the program has caught the intercept, or if the terminal/program is hanging, ^c
I thought they were referring to copy and pasting. There's been many times in the past I've gone to paste something and it wasn't the thing I though I just copied half a second ago. It has resulted in me abusing control + c.
