PRS-T1 How to get Kindle-for-Android turn pages using hardward buttons?

On my rooted PRS-T1, I have installed Kindle-for-Android to read my Amazon ebooks. But I have to use left/right swipes on the touch screen to turn to previous/next pages.

Is there a way to use the hardware buttons on the PRS-T1 to turn pages when reading by Kindle-for-Android?

Thanks!
