Key Usage Because UNIX terminals vary widely, the keys documented in the books may not be available on your keyboard. Also, most UNIX terminals do not send a sequence when the Alt or Ctrl key is pressed, so the COBOL system cannot detect these keys. The appendix UNIX Key Usage Chart in your COBOL System Reference lists alternatives for keys that may be undetectable on your specific UNIX terminal, and shows which keys you may be able to configure. The appendix also tells you how to select soft or hard operation for the Alt and Ctrl keys. With soft operation, the Alt or Ctrl key is automatically turned off after the next keystroke. This means that whenever you want a function from the Alt menu you must hold down Alt again to get theAlt menu displayed; and similarly with Ctrl. With hard operation, the Alt and Ctrl keys work in a similar way to the Caps Lock key, in that having been pressed they remain in effect until pressed again. For information on configuring your keyboard, see the chapter Keyboard Configuration Utility in your COBOL System Reference.
