moving backwards and forwards in Itunes windows

Other Apple Chat

I have started listening to audiobooks on Itunes recently, however whilst its good at keeping its place when I click on the book, sometimes it doesnt for some reason.

My question is how do I revind and forward while listening to the book?
Using latest version of Itunes on windows with jaws.
FS page on ITunes says to use the windows alt ctrl left and right arrows, however that just flips the orientation of my screen and doesnt move the book forwards or backwards.
