Using Command Line Shortcut Keys
System-defined shortcut keys cannot be defined by users and have fixed functions. Table 1 lists the system-defined shortcut keys.
The terminal in use may affect the functions of the shortcut keys because the shortcut keys entered by the user are captured by the terminal program. For example, if the shortcut keys defined by the terminal conflict with those defined in the system, the commands corresponding to the shortcut keys are not executed.
