Assuming I understand your question: On an IBM PC keyboard there is a key labeled Ctrl which stands for Control. For a number of functions they will say Press Ctrl plus some other key. For example, Ctrl+C (sometimes written Ctrl-C) copies just like the copy function in the Edit menu. To copy using Ctrl+C, highlight the area you want to copy, press the Ctrl key and while holding it down, press the C key on the keyboard.
Try pressing <Ctrl> + <Shift> + <Esc> instead.
