Control Key and ASCII Codes
While the primary function of the control key is to act in conjunction with other keys to execute various commands, it also plays a role in entering control codes. Control A, for example, has an ASCII code of 1, and Control Z has an ASCII code of 26. However, the actual responses from programs to these control codes vary and depend on the specific programs and operating systems in use. In Windows, ^A is typically used to select all, ^C for copy, ^X for cut, ^V for paste, and ^Z for undo.
This shows that the control key is the oldest and most universally accepted method for sending control codes, whereas other keys such as Alt and function keys are more specific to certain systems and applications. They do not have standard ASCII codes like the control key does.
