My question is how do I get the page down and page up button to work on the left hand side of the screen. I have looked at the wizard implementation with the page up and page down command but when I have two pages on say my TV and I have done the two pages using the tab one of two and two of two from the graphic gallery the page up and down no longer work unless I assign in the activities that the page up button is actually a page jump and the same for the page up is assigned a page jump. The tabs also don't work unless I assign it a page jump instead of the normal page down and page up.

Hope this is not too confusing.
Can someone please enlighten me on this?
I actually want to understand how it works and not just cut and paste please.

Thanks
