Turn off nav with arrow keys?

[Magnus von Brömsen]

Hi

I want to turn of the possibilities to navigate from card-to-card with 
the arrow keys (in a stand-alone app).

Is this the right way to go:

on openCard
     set the navigationsArrow to false
end openCard

The app is made of 3 stack-files, so I put this script i each 
main-stack. Or...?

Thanks.
