Not sure if anyone has answered you or not. I have found that f6 on the keyboard brings up the FF RW triangle square thingy. With which moving your mouse left and right on the square moves it to the bottom of the screen and from there the "location" bar with the FF and RW speeds controlled by how far you move the mouse to the left and right respectively in the "location" bar thingy. I believe also in the triangle square thingy that Up and down with the mouse controls the audio up and down.
Hope this helps.
