Ctrl-C is the shortcut commonly used by Windows, X-Windows, and Mac OS (and likely other Operating Systems) to "copy" data (files, folders, text, images, etc) to a temporary holding place known as the "clipboard." In console-based Operating Systems, Ctrl-C was commonly designated as a key to cancel the current program abruptly. To use Ctrl-C, one must first press and hold Ctrl, and with another finger, press the "c" key. When using a virtual keyboard or "Sticky Keys", one may press Ctrl, release it, then press the "c" key.
