Air Display - Scrolling control

[golftuck4]

I'm using Air Display to make an ipad into an extended screen. On the iPad side of the screen, there is a word document that receives text from a document on the mac side via a VBA macro. The person using the iPad needs to be able to scroll through the document, but I need that to happen without it moving the curser to the ipad side of the screen because the person on the mac side needs a cursor to be able to send the text to the iPad document and scroll in their own document. Is there any way to make this work in Air Display or is there another application that will provide this capability in some way? Thanks!
