Query form: SYSTem:KEY? [MINimum MAXimum]

Response: <NR1>

<NR1>	Reference number of the last key for which pressing
	was simulated.

If MINimum was specified, the minimum possible key number is returned.

If MAXimum was specified, the maximum possible key number is returned.

Description:

The SYSTem:KEY command simulates the action of pressing a front panel key, specified by the rounded integer value of the key number.

The SYSTem:KEY? query returns the key number corresponding to the last key that was pressed. A value of -1 indicates that no key was pressed since power on or after a *RST command. If the URQ (user request) bit in the standard Event Status Register (ESR) is set, a key on the front panel has been pressed. This URQ bit can be used to signal the event of pressing a key on the front panel to the controller.

Note: With this command the pressing of one key at the same time is simulated. A combination, e.g., STATUS + TEXT OFF at the same time, cannot be simulated. The command execution is finished directly. However, the actions that take place in the instrument as a result of a SYSTem:KEY command, can last longer. A SYSTem:KEY command cannot be synchronized by sending a *WAI or *OPC? immediately thereafter.

Example: SYSTem:KEY 101;*WAI continues program execution immediately (*WAI ignored), although the AUTOSET (= key 101) still continues for a few seconds.
