The hard buttons are Info and Return, known as PS_BACK and PS_EXIT in ProntoScript Dev Guide Appendix. Back and Exit from PEP1 Hard Button Links in Editor.

There are only 5 buttons beneath screen. I suspect they did this to avoid having to change graphics between 9600 and 9800.

The jog wheel is also metal one like on the 9400.

And... There's a switch on the back of docking station to turn off LED.

All this info is gleaned from experience and pics posted on www.OnlyOneRemote.com
