Ctrl+C is a leftover from Baldur's Gate II: Throne of Bhaal that seems to have stayed with the engine. It should show the character write-ups for the end-game that would normally roll after you completed Throne of Bhaal (though it never worked properly), but no such write-ups exist in the first game.
Does pressing the button combination actually break anything (quest/script wise)? Or are you just saying not to press the button because it is pointless?

Just don't press that combination.
