With touch screen E Ink Kindle devices, is there some way to trigger the back button / action without having to tap twice (i.e. once to trigger the top menu and then again to press the back button)? I'm not referring to flipping back a page but rather the back button itself which is useful when jumping back to where you were before pressing a link. I'm using the Voyage but I think if there is an answer it may apply to Paperwhite and the regular Kindle touch too.
No. I have found no way of doing this with my Paperwhite (and I have tried quite a few things). This would be very useful to have; perhaps if we suggest it to Amazon, it may become a feature?
