capture fast forward remote click in roTextScreen

I am trying to capture the fast forward remote click on roTextScreen. I am using roTextScreenEvent but this doesnt have isRemoteKeyPressed. I am able to use the remote on this page, fast forward and ok remote button both 'do things' on my screen I just cant get hold of the event/action.

I need to continue to use roTextScreen due to the amount of text (this is a EULA page).

I am doing a pretty standard event loop

    while true
        msg = wait(0, screen.getMessagePort())
        if type(msg) = "roTextScreenEvent"
            print "type: " type(msg)
            print "message: " msg
            if msg.isButtonPressed()
                idx = msg.getIndex()
                if valid(opts.buttons) and valid(opts.buttons[idx]) then
                    res = opts.buttons[idx].action(screen)
                end if
            else if msg.isRemoteKeyPressed() 'this doesnt work
                'print "remote index: " ; msg.getIndex()
            else if msg.isScreenClosed()
                exit while
            end if 
        
        endif
    end while
