Key activation can be transmitted to the user program and evaluated there.
Thus, an action such as switching on a motor can be initiated.

Transmission of the keyboard image is filtered depending on the state of the
C7-613. Keyboard operations that trigger internal responses (for example,
completing an input with ENTER or changing between standard/special screens)
are not relayed.
