Arrow keys for jogging

The GMOCCAPY documentation indicates that the arrow-keys, pg-up, pg-down are enabled by default, however, they are not responding on my installation from the main screen. I've looked for a configuration parameter to enable them, but the only key I found disables all hot keys, not just the jog keys. Am I doing something wrong or did I miss something in the documentation?

So sorry, I miss read the documentation, it says that the keyboard arrow keys are DISabled by default and to enable them just check the box. Where is the box? I don't see one on the screen, the settings page or anywhere else that enables the arrow keys. Can someone shed some light on where or how to enable the arrow keys?

Kind regards,
