simhub vocore controls are not working?

Hello,

today my new Vocore dislpay arrived and is working well.

Now I tried to use in the Dash Studio under Vocore the points:

Vocore controls:

Cycle next dash template

Show next screen 

...

But there ist no possibility to define a keyboard key like "a" oder "shift-a" as an action.

So it would be possible to go quickly through the screens.

There is only a dropdown menu, where I can change the dropdown, but can not define a required action like a keyboard input.

Please help.

Thanks a lot.
