I read on the reader screen and work in table of content (TOC) on the tablet screen while listen to the audio.

For this I created playlists that jumb over different chapters in the book. To navigate to the next chapter on the reader I needed to pause the audio and go back to TOC to navigate to the next chapter.

It would be great to have the pause/play function for audio assigned to one of the hardware buttons, that way I could stay on TOC screen all the time, and saving time instead of going in and out.

(BTW: for the ipod it works fine with external controls on the headphone, with volume up/down and pause/play, I prefer to read on the EE :-)
