the German keyboard layout uses Strg as required by the German standard DIN 2137:2012-06. Abbreviations in the language of the keyboard layout also are in use. On keyboards that use English abbreviations for key labeling, it is usually labeled Ctrl (rarely, Control or Ctl is seen). The Control key is located on or near the bottom left side of most keyboards (in accordance with the international standard ISO/IEC 9995-2), with many featuring an additional one at the bottom right. In computing, a Control key Ctrl is a modifier key which, when pressed in conjunction with another key, performs a special operation (for example, Ctrl+ C) similar to the Shift key, the Control key rarely performs any function when pressed by itself.
