I used all Components like PosterGrid, ZoomRowList, and TimeGrid. But, every Component Automatic Scroll using FF/RW key. I need to Stop Scrolling with that Component. I found a specific Field at Rowlist which is fadeFocusFeedbackWhenAutoScrolling. There is a specific field for other components? I also applied the below code :

if key = "fastforward" or key = "rewind" then //also I tried with "and" keyword
return 
end if

But no luck. Does anyone know How can I stop Scrolling keys inside a List and Grid Nodes?
