If MINimum was specified, the minimum possible key number is

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
